Who was the scientist who gave us laws of motion?
- A.
Albert Einstein
- B.
Isaac Newton
- C.
James Watt
- D.
Thomas Edison
Correct Answer
B. Isaac NewtonExplanation
Isaac Newton is the correct answer because he was the scientist who formulated the laws of motion. His three laws of motion, known as Newton's laws, describe the relationship between the motion of an object and the forces acting upon it. These laws are fundamental principles in physics and have had a significant impact on our understanding of motion and mechanics. Albert Einstein, James Watt, and Thomas Edison were also influential scientists, but they are not specifically known for formulating the laws of motion.Rate this question:

How many laws of motion are there?
- A.
One
- B.
Two
- C.
Three
- D.
Four
Correct Answer
C. ThreeExplanation
The correct answer is three because Sir Isaac Newton formulated three fundamental laws of motion. These laws describe the relationship between the motion of an object and the forces acting upon it. The first law states that an object at rest will remain at rest, and an object in motion will continue in motion with a constant velocity unless acted upon by an external force. The second law states that the force acting on an object is equal to its mass multiplied by its acceleration. The third law states that for every action, there is an equal and opposite reaction.Rate this question:

What is another name for the first law of motion?
- A.
Acceleration
- B.
Force
- C.
Momentum
- D.
Inertia
Correct Answer
D. InertiaExplanation
The first law of motion is also known as inertia. Inertia is the tendency of an object to resist changes in its motion or rest. It states that an object at rest will stay at rest, and an object in motion will continue moving at a constant velocity, unless acted upon by an external force. Inertia is directly related to the mass of an object, as objects with greater mass have greater inertia.Rate this question:

Which law of motion explains why we need to wear seatbelts?
- A.
First Law of Motion
- B.
Second Law of Motion
- C.
Third Law of Motion
- D.
National Highway Traffic and Safety Administration
Correct Answer
A. First Law of MotionExplanation
The First Law of Motion, also known as the law of inertia, explains why we need to wear seatbelts. This law states that an object at rest will stay at rest, and an object in motion will stay in motion, unless acted upon by an external force. In the case of a car accident, the sudden change in motion can cause passengers to continue moving forward at the same speed the car was traveling before the accident. Seatbelts help to restrain passengers and prevent them from being thrown forward, reducing the risk of injury.Rate this question:

Which law says that force is equal to mass x acceleration?
- A.
Third law of motion
- B.
Second law of motion
- C.
First law of motion
- D.
None of the above
Correct Answer
B. Second law of motionExplanation
The second law of motion, also known as Newton's second law, states that force is equal to the product of mass and acceleration. This means that the force exerted on an object is directly proportional to its mass and the acceleration it experiences. In mathematical terms, force (F) is equal to mass (m) multiplied by acceleration (a), or F = m x a. This law helps explain how objects move and interact with each other when forces are applied to them.Rate this question:

Which law says that heavier objects require more force to move or accelerate than lighter objects?
- A.
Law of Conservation of Momentum
- B.
First law of motion
- C.
Second law of motion
- D.
Third law of motion
Correct Answer
C. Second law of motionExplanation
The second law of motion, also known as Newton's second law, states that the force acting on an object is directly proportional to the mass of the object and its acceleration. This means that heavier objects require more force to move or accelerate than lighter objects.Rate this question:

Which law explains how rockets are launched into space?
- A.
Law of Conservation of Momentum
- B.
First law of motion
- C.
Second law of motion
- D.
Third law of motion
Correct Answer
D. Third law of motionExplanation
The third law of motion, also known as Newton's third law of motion, explains how rockets are launched into space. According to this law, for every action, there is an equal and opposite reaction. In the case of a rocket, the action is the expulsion of gases at high speeds through the rocket's engines, and the reaction is the force that propels the rocket forward. This law allows rockets to generate the necessary thrust to overcome Earth's gravity and launch into space.Rate this question:

Which law says that for every action there is an equal and opposite reaction?
- A.
Law of thermodynamics
- B.
Law of Conservation of Momentum
- C.
Third law of motion
- D.
Second law of motion
Correct Answer
C. Third law of motionExplanation
The correct answer is the Third law of motion. This law, also known as Newton's third law of motion, 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 equal magnitude but in the opposite direction on the first object. This law is fundamental in understanding the interactions between objects and is applicable in various fields such as physics and engineering.Rate this question:

After they removed their gloves and they were floating in the Apollo capsule, the gloves stopped moving.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement implies that the gloves stopped moving after they were removed and were floating in the Apollo capsule. However, since the gloves were removed, they would not be floating in the capsule anymore. Therefore, the statement contradicts itself and is false.Rate this question:

When they were thrown forward into their seat harnesses, the astronauts were demonstrating the First Law of Motion.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because the First Law of Motion, also known as Newton's Law of Inertia, states that 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. In this case, when the astronauts were thrown forward into their seat harnesses, they were experiencing the force that caused them to change their state of motion, demonstrating the First Law of Motion.Rate this question:
