Multiple Choice

When a car suddenly stops and your body continues to move forward, which law of motion is being demonstrated?

• Newton's First Law

• Newton's Second Law

• Newton's Third Law

• Law of Universal Gravitation

Multiple Choice

Based on the baseball example, what would happen to the ball's acceleration if the mass of the ball increased but the force applied remained the same?

• The acceleration would decrease.

• The acceleration would increase.

• The acceleration would stay the same.

• The acceleration would become zero.

Multiple Choice

Which of the following best describes the action and reaction forces involved when a rocket launches upward?

• Engine pushes gas down; gas pushes rocket up

• Rocket pushes air up; air pushes rocket down

• Engine pulls rocket up; gravity pulls rocket down

• Rocket pushes ground down; ground pushes rocket up

Multiple Choice

Why is it sometimes difficult to observe the reaction force when you walk, according to the Third Law of Motion?

• Because the mass of the Earth is so large, it does not move in response.

• Because the force applied is too small to measure.

• Because the reaction force is always invisible.

• Because the walking force is not paired with any reaction.

Multiple Choice

Which of the following best describes 'force' as used in Newton's Laws of Motion?

• A push or pull that causes an object to change its motion or shape.

• The rate of change of velocity (speed with a direction).

• The energy stored in an object due to its position.

• The resistance of an object to a change in its state of motion.
