How can you tell if an object is in motion?
- A.
The object will look different.
- B.
I'll be able to see the forces.
- C.
It will remain in the same position.
- D.
Its position will change in relation to other objects.
Correct Answer
D. Its position will change in relation to other objects.Explanation
When an object is in motion, its position will change in relation to other objects. This means that the object will move from one place to another and its location will be different compared to other stationary objects. This change in position is a clear indication that the object is in motion. The other options are incorrect because simply looking different or being able to see forces does not necessarily indicate motion, and if the object remains in the same position, it is not in motion.Rate this question:

"Position" is
- A.
A type of contact force
- B.
A specific location
- C.
A type of motion
- D.
Another name for friction
Correct Answer
B. A specific locationExplanation
The term "position" refers to a specific location rather than any other options provided. In physics and mathematics, position is used to describe the exact point or place where an object is located in space or on a coordinate system. It provides a precise description of where something is situated, allowing for accurate measurements and calculations.Rate this question:

Gravity and magnetism are examples of what kind of forces?
- A.
Friction
- B.
Non-contact
- C.
Contact
- D.
Momentum
Correct Answer
B. Non-contactExplanation
Gravity and magnetism are examples of non-contact forces because they can act on objects without physical contact between them. Unlike contact forces, such as friction or momentum, which require direct interaction between objects, gravity and magnetism can exert their influence over a distance. This is evident in the way gravity pulls objects towards the Earth or how magnets can attract or repel each other without any direct contact.Rate this question:

A person is measured on the moon and on Earth. Which statement is true?
- A.
The person's mass on Earth would be double on the moon.
- B.
The person's mass on the moon would be twice that on Earth.
- C.
The person would have mass on Earth but not on the moon.
- D.
The mass would be the same on the moon as it is on Earth.
Correct Answer
D. The mass would be the same on the moon as it is on Earth.Explanation
The mass of an object is a measure of the amount of matter it contains, and it remains constant regardless of the location. Therefore, the mass of a person would be the same on the moon as it is on Earth. The force of gravity may be different on the moon compared to Earth, resulting in a different weight, but the mass itself would not change.Rate this question:

A person is measured on the moon and on Earth. Which statement is true?
- A.
The mass would be the same on the moon as it is on Earth, but the weight would be more on the moon than it is on Earth.
- B.
The weight would be the same on the moon as it is on Earth, and the mass would be more on the moon than it is on Earth.
- C.
The mass and weight would be the same on the moon as it is on Earth because mass is another name for weight.
- D.
The mass would be the same on the moon as it is on Earth, but the weight would be more on Earth than it is on the moon.
Correct Answer
D. The mass would be the same on the moon as it is on Earth, but the weight would be more on Earth than it is on the moon.Explanation
Weight is directly proportional to the amount of gravity. Since Earth has more gravity than the moon, a person would weigh more on Earth.Rate this question:

How can you tell if an object is experiencing an unbalanced net force?
- A.
It might speed up.
- B.
It might slow down.
- C.
It might change direction.
- D.
It might do any of the three things mentioned above.
Correct Answer
D. It might do any of the three things mentioned above.Explanation
If an object at movement is receiving an unbalanced force, it means that the net force acting on the object is not zero. In this case, the object might speed up because the force is causing an acceleration in the same direction as the motion. Alternatively, it might slow down if the force is acting in the opposite direction of the motion, causing deceleration. Additionally, the object might change direction if the force is acting perpendicular to the motion, causing the object to move in a curved path. Therefore, any of the three mentioned outcomes are possible when an object is receiving an unbalanced force.Rate this question:

A plane flew from NY to California in 4 hours. It took 4 1/2 hours to return to NY. Which of the following is true:
- A.
The plane flew faster to NY than it flew to California.
- B.
The plane flew faster to California than it flew to NY.
- C.
The plane flew at the same speed in both directions.
- D.
The plane had fewer passengers going to NY than it did to California.
Correct Answer
B. The plane flew faster to California than it flew to NY.Explanation
Since it took less time (4 hours) for the plane to fly from NY to California compared to the time it took (4 1/2 hours) to return to NY, it can be concluded that the plane flew faster to California than it flew to NY.Rate this question:

Why is it difficult to move a bed from one end of the room to the other?
- A.
Momentum
- B.
Gravity
- C.
Friction
- D.
Deceleration
Correct Answer
C. FrictionExplanation
Friction is the force that opposes the motion of objects in contact with each other. When trying to scoot a bed from one end of the room to the other, the bed experiences friction with the floor. Friction makes it difficult to move the bed because it creates resistance, requiring more force to overcome. The rough surface of the floor and the weight of the bed increase the friction, making it even harder to move. Therefore, friction is the reason why it is difficult to scoot a bed from one end of the room to the other.Rate this question:

Which of Newton's Laws is demonstrated by a soccer ball rolling on grass?
- A.
Newton's First Law
- B.
Newton's Second Law
- C.
Newton's Third Law
- D.
Newton's Law of Acceleration
Correct Answer
A. Newton's First LawExplanation
A soccer ball kicked on a grass field gradually slows down and stops due to the resistance from the grass and air. In the absence of these forces, the ball would keep rolling.Rate this question:

Why do you lean towards the left when a car turns right?
- A.
Because of inertia
- B.
Because of gravity
- C.
Because of buoyancy
- D.
Because of velocity
Correct Answer
A. Because of inertiaExplanation
When a car turns right, the passengers inside the car tend to lean towards the left due to inertia. Inertia is the tendency of an object to resist changes in its motion. As the car turns, the passengers' bodies want to continue moving in a straight line due to their inertia. This causes them to lean in the opposite direction of the turn, towards the left. The force of inertia acts against the centripetal force that keeps the car moving in a curved path, resulting in the leaning sensation experienced by the passengers.Rate this question:
