Amplify- Force and Motion Unit Test

Front

What is force?

Back

A push or pull that can cause motion.

Front

In which direction must a force act for an object to speed up?

Back

In the same direction as the object's motion.

Front

What happens when a force is applied in the opposite direction of an object's motion?

Back

It slows down the object.

Front

What is the relationship between mass and force experienced by an object?

Back

More massive objects experience greater force when acted upon.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the effect of friction on motion?

Back

Friction opposes motion and can cause an object to slow down or stop.

Front

How does the mass of an object affect its acceleration when a force is applied?

Back

Greater mass results in less acceleration for the same amount of force (Newton's second law).

Front

What is Newton's first 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 the formula for calculating force?

Back

Force = mass × acceleration (F = ma).

Front

What is the role of a net force in motion?

Back

The net force determines the direction and magnitude of an object's acceleration.
