Force and Motion Unit Exam

Front

What happens to the motion of an object when a strong force is applied in the same direction as its motion?

Back

The object will speed up.

Front

What is the tendency of matter to resist a change in motion called?

Back

Inertia (Newton's 1st Law)

Front

In a collision, if both objects receive equal force strength, in what direction are the forces exerted?

Back

In opposite directions.

Front

If all objects are moving at the same speed, which object has the greatest kinetic energy: tennis ball, ping pong ball, hockey puck, or bowling ball?

Back

Bowling ball.

Front

What is the effect of applying a strong force in the opposite direction to the motion of a slow-moving object?

Back

The object will change directions and continue moving.

Front

Define force in the context of motion.

Back

A push or pull that can cause an object to accelerate.

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is kinetic energy?

Back

The energy an object has due to its motion.

Front

How does mass affect the kinetic energy of an object?

Back

Kinetic energy increases with mass if speed is constant.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic Energy (KE) = 1/2 mv², where m is mass and v is velocity.
