A force is a:
A.
State of matter
B.
Energy
C.
Direction
D.
Push or pull
E.
Equal to zero
Correct Answer
D. Push or pull
Explanation A force is a push or pull that can cause an object to accelerate or change its motion. It is a physical interaction between two objects or within an object, and it can be measured and quantified. Forces can be exerted in various directions and magnitudes, and they can be applied to both stationary and moving objects. Therefore, the correct answer is "push or pull."

The three types of force are:
A.
Gravity, friction, balanced
B.
Balanced, unbalanced, gravity
C.
Contact, gravity, balanced
D.
Unbalanced, balanced, friction
E.
Contact, gravity, friction
Correct Answer
E. Contact, gravity, friction
Explanation The correct answer is contact, gravity, friction. Contact force refers to the force exerted when two objects are in physical contact with each other. Gravity is the force that attracts objects towards each other due to their mass. Friction is the force that opposes the motion of objects when they move against each other or against a surface. These three types of forces are fundamental in understanding the interactions between objects in the physical world.

Which one represents a contact force?
A.
The attraction of the moon to the earth
B.
Rubbing your hands together
C.
Steam from a hot beverage
D.
Sean pushing against a wall
E.
Ice melting
Correct Answer
D. Sean pushing against a wall
Explanation Sean pushing against a wall represents a contact force. Contact forces are forces that result from direct physical contact between two objects. In this case, Sean's push is exerted on the wall through direct contact, creating a contact force. The other options mentioned, such as the attraction of the moon to the earth, rubbing hands together, steam from a hot beverage, and ice melting, do not involve direct physical contact and therefore do not represent contact forces.

A box sitting on a table represents.
A.
Only an upward force
B.
A vector
C.
Friction
D.
Motion
E.
A balanced force
Correct Answer
E. A balanced force
Explanation A box sitting on a table represents a balanced force because it is not moving or accelerating in any direction. The force of gravity pulling the box downwards is balanced by the normal force exerted by the table upwards, creating an equilibrium. Since there is no net force acting on the box, it remains stationary.

A car traveling at constant speed represents:
A.
Steam
B.
Static
C.
Contact force
D.
Unbalanced force
E.
Balanced force
Correct Answer
E. Balanced force
Explanation A car traveling at a constant speed represents a balanced force. This means that the forces acting on the car are equal and opposite, resulting in no net force acting on the car. As a result, the car maintains a constant speed without accelerating or decelerating.
Rate this question:
7.
The overall force acting on an object when all the forces are combined is called the _____ force.
Correct Answer net Net
Explanation The overall force acting on an object when all the forces are combined is called the net force. The term "net" is used to describe the combination or sum of all the forces acting on an object. It represents the total or resultant force that determines the object's motion or equilibrium. The word "Net" is simply a variation or alternative spelling of "net" and has the same meaning in this context.
Rate this question:
8.
Does an object always move when a force acts upon it?
A.
Yes
B.
No
Correct Answer
B. No
Explanation An object does not always move when a force acts upon it. According to Newton's first law of motion, an object at rest will remain at rest, and an object in motion will continue moving at a constant velocity, unless acted upon by an external force. Therefore, if the force acting on an object is balanced by other forces or if the object is already in motion and the force is not strong enough to change its velocity, the object may not move.
Rate this question:
9.
A chair at rest is pulled by a student out from under a desk. This pull results in ...
A.
A balanced force.
B.
An unbalanced force.
C.
Extra gravity.
Correct Answer
B. An unbalanced force.
Explanation When a chair at rest is pulled by a student out from under a desk, it experiences an unbalanced force. This is because the student's pull creates a force that is greater than the force of friction between the chair and the floor. As a result, the chair accelerates in the direction of the pull, indicating an unbalanced force acting on it.
Rate this question:
10.
An object at rest remains at _____, an object in motion remains in motion unless acted upon by an outside force.
Correct Answer rest
Explanation Newton's First Law of Motion states that an object will remain at rest or continue moving at a constant velocity unless acted upon by an external force. This principle, known as inertia, describes the tendency of objects to maintain their current state of motion unless influenced by an outside factor.
Rate this question:
11.
Balanced forces cannot change an object's speed or _____.
Correct Answer direction direction. Direction
Explanation Balanced forces cannot change an object's speed or direction. This means that when the forces acting on an object are equal in magnitude and opposite in direction, there is no net force acting on the object. As a result, the object will continue to move at a constant speed in the same direction.
Rate this question:
12.
The resistance of an object to change in speed or direction.
A.
Newton's first law
B.
Newton's second law
C.
Newton's third law
D.
Inertia
E.
Acceleration
Correct Answer
D. Inertia
Explanation Inertia is the correct answer because it refers to the resistance of an object to change in speed or direction. According to Newton's first law of motion, an object at rest will stay at rest and an object in motion will stay in motion with the same speed and direction unless acted upon by an external force. This concept of inertia explains why objects tend to maintain their current state of motion unless acted upon by an external force.
Rate this question:
13.
The force of an object is proportional to the mass and acceleration of that object.
A.
Newton's first law
B.
Newton's second law
C.
Newton's third law
D.
Centripetal force
E.
Inertia
Correct Answer
B. Newton's second law
Explanation Newton's second law states that the force acting on an object is equal to the mass of the object multiplied by its acceleration. This means that the force is directly proportional to both the mass and acceleration of the object. Therefore, the given statement aligns with Newton's second law, making it the correct answer.
Rate this question:
14.
The force that keeps an object traveling in a circular motion.
A.
Newton's first law
B.
Newton's second law
C.
Newton's third law
D.
Inertia
E.
Centripetal
Correct Answer
E. Centripetal
Explanation Centripetal force is the force that keeps an object traveling in a circular motion. It acts towards the center of the circle and is required to counterbalance the object's tendency to move in a straight line. This force is responsible for continuously changing the direction of the object's velocity, allowing it to stay in the circular path. Newton's first law, second law, and third law do not specifically address the concept of centripetal force. Inertia, on the other hand, is the tendency of an object to resist changes in its motion and is not directly related to circular motion.

Two shopping carts are pushed with the same force. One has a lower acceleration than the other. Which is an example that could explain this reaction?
A.
One shopping cart is full, and the other is empty.
B.
The person pushing a cart is larger than the other.
C.
One is pink.
D.
One is at a higher elevation
Correct Answer
A. One shopping cart is full, and the other is empty.
Explanation When one shopping cart is full and the other is empty, the full cart will have a larger mass compared to the empty cart. According to Newton's second law of motion, the acceleration of an object is inversely proportional to its mass when the force applied on it is constant. Therefore, the full cart with a larger mass will have a lower acceleration compared to the empty cart with a smaller mass, even if the same force is applied to both carts.

Using the Formula F=MA (Force + Mass x Acceleration), solve the following problem. What is the force applied to the football when the football has a mass of 6kg, and it travels at an acceleration of 3m/s2
A.
2 N
B.
0.5 N
C.
2 kg /s2
D.
18 kg
E.
18 N
Correct Answer
E. 18 N
Explanation The correct answer is 18 N. According to the formula F = MA, where F is the force, M is the mass, and A is the acceleration, we can plug in the given values. The mass of the football is 6kg and the acceleration is 3m/s2. Therefore, the force applied to the football is 6kg x 3m/s2 = 18 N.

An Elephant is pulled by a group of clowns across a circus. The elephant has a mass of 1000kg and the clowns are pulling with a force of 200N. What is the acceleration of the elephant?
A.
0.2 N
B.
0.2 m/s
C.
0.2 m/s2
D.
0.2 kg
E.
0.2 Nm/s
Correct Answer
C. 0.2 m/s2
Explanation The acceleration of an object is determined by the net force acting on it and its mass, according to Newton's second law of motion (F=ma). In this scenario, the clowns are pulling the elephant with a force of 200N and the elephant has a mass of 1000kg. Therefore, the acceleration of the elephant can be calculated by dividing the force by the mass: 200N / 1000kg = 0.2 m/s2.
Rate this question:
18.
A race car has an acceleration of 4 m/s2 and the force of the engine is 8 N. Assuming the race car is on the earth, what is the weight of the car?
A.
0.5 N m/s2
B.
0.5 kg
C.
2 N m/s2
D.
2 kg
E.
32 kg
Correct Answer
D. 2 kg
Explanation The weight of an object is equal to the force of gravity acting on it. In this case, the weight of the car can be calculated using the formula weight = mass x acceleration due to gravity. Since the acceleration given is the acceleration of the car, not the acceleration due to gravity, we cannot directly calculate the weight of the car. Therefore, the given answer of 2 kg is not a valid explanation.

A.
The batter
B.
The force of friction
C.
The force of gravity
D.
The force of inertia
E.
The contact force
Correct Answer
E. The contact force
Explanation The baseball's change in motion was the direct result of the contact force. When the baseball is hit by the bat, the contact force between the bat and the ball causes the ball to accelerate and change its direction. This force is responsible for propelling the ball out of the pitcher's hand and towards the home run.

Finish this statement. For every action, there is an _____ and opposite reaction.
A.
Obstacle
B.
Aversion
C.
Equal
D.
Opposite
E.
Acceleration
Correct Answer
C. Equal
Explanation For every action, there is an equal and opposite reaction. This means that whenever an object exerts a force on another object, the second object exerts a force of the same magnitude but in the opposite direction on the first object. This principle is known as Newton's third law of motion and is applicable in various scenarios, such as a person pushing against a wall or a rocket propelling itself forward by expelling gasses backward.

What pushes a bird through the air? (use Newton's third law)
A.
It's wings
B.
The air
C.
Sound
D.
Light
E.
Fire
Correct Answer
B. The air
Explanation The correct answer is the air. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. When a bird flaps its wings, it creates a downward force on the air, and in turn, the air exerts an upward force on the bird, pushing it through the air. Therefore, it is the air that pushes the bird through the air, based on Newton's third law.

A.
0 N
B.
5 N
C.
10 N
D.
50 N
E.
250 N
Correct Answer
E. 250 N
Explanation The wall hits the person with a force of 250 N because the force exerted by the person on the wall is equal in magnitude and opposite in direction to the force exerted by the wall on the person, as per Newton's third law of motion. Therefore, the wall exerts a force of 250 N on the person.

A guy pushes on a car causing himself to slide backward away from the car. This is an example of:
A.
Balanced force
B.
Unbalanced force
C.
Newton's first law
D.
Newton's second law
E.
Newton's third law
Correct Answer
E. Newton's third law
Explanation When the guy pushes on the car, according to Newton's third law of motion, the car exerts an equal and opposite force on the guy. This causes the guy to slide backward away from the car. Newton's third law states that for every action, there is an equal and opposite reaction. In this case, the action is the guy pushing on the car, and the reaction is the car pushing back on the guy, causing him to move in the opposite direction.

The momentum of an object is related to its:
A.
Mass and momentum
B.
Mass and speed
C.
Mass and acceleration
D.
Mass and velocity
E.
Mass and force
Correct Answer
D. Mass and velocity
Explanation The momentum of an object is related to its mass and velocity. Momentum is defined as the product of an object's mass and its velocity. The greater the mass of an object and the faster it is moving, the greater its momentum will be. This relationship is described by the equation p = m * v, where p is the momentum, m is the mass, and v is the velocity of the object. Therefore, the correct answer is mass and velocity.

A pool ball slows down after hitting another pool ball that speeds up. This is an example of:
A.
Friction
B.
Conservation of momentum
C.
The force of gravity
D.
Newton's second law of motion
E.
The collision matrix
Correct Answer
B. Conservation of momentum
Explanation When two pool balls collide, the total momentum before the collision is equal to the total momentum after the collision. In this scenario, one pool ball speeds up while the other slows down, but the total momentum remains the same. This is because momentum is conserved in collisions, meaning that the total amount of momentum in a system does not change unless an external force is applied. Therefore, the correct answer is conservation of momentum.

An action force and its reaction force are:
A.
Equal in size and direction
B.
Equal in size and opposite in direction
C.
Different in size but in the same direction
D.
Different in size and in direction
Correct Answer
B. Equal in size and opposite in direction
Explanation An action force and its reaction force are equal in size and opposite in direction. This is known as Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. This means that whenever an object exerts a force on another object, the second object exerts a force of the same magnitude but in the opposite direction on the first object. This principle is fundamental in understanding the interactions between objects and the conservation of momentum in physics.

John pulls a box with a force of 4N, and Jason pulls the box from the opposite side with a force of 3N. Ignore friction. Which of the following statements is true?
A.
The box moves toward John
B.
The box moves toward Jason
C.
The box does not move
D.
There is not enough information to determine if the box moves.
Correct Answer
A. The box moves toward John
Explanation In this scenario, John exerts a force of 4N while Jason exerts a force of 3N in the opposite direction. Since John's force is greater than Jason's force, the net force acting on the box is 4N - 3N = 1N in the direction of John. According to Newton's first law of motion, an object will move in the direction of the net force acting on it. Therefore, the box will move towards John.

Two cars accelerate at a rate of 3 meters per second squared (m/s2). The mass of each car, in kilograms (kg), is shown below.
Car A 1250 kg
Car B 2000 kg
How many more newtons (N) of force is needed to accelerate the car with the larger mass?
A.
750 N
B.
1250 N
C.
2000 N
D.
2250 N
E.
6000 N
Correct Answer
D. 2250 N
Explanation The force needed to accelerate an object is directly proportional to its mass. Since Car B has a larger mass than Car A, it will require more force to accelerate. The difference in mass between the two cars is 2000 kg - 1250 kg = 750 kg. Therefore, the force needed to accelerate Car B is 750 kg * 3 m/s^2 = 2250 N.
