Force and Motion Test Review

Front

What is force?

Back

A push or pull on an object that can cause it to move, stop, or change direction.

Front

What is motion?

Back

The change in position of an object over time.

Front

What is friction?

Back

A force that opposes the motion of an object, acting in the opposite direction.

Front

What is gravity?

Back

A force that pulls objects toward each other, such as the pull of the Earth on objects.

Front

What is mass?

Back

The amount of matter in an object, which affects how much force is needed to move it.

Front

What happens when a force is applied to an object?

Back

The object may start moving, stop moving, or change direction depending on the force applied.

Front

What is the relationship between force and motion?

Back

Force causes motion; without force, an object at rest will stay at rest.

Front

What is the effect of a greater force on an object?

Back

A greater force can overcome friction and cause the object to move.

Front

What is the role of a balanced force?

Back

Balanced forces do not change the motion of an object; they keep it at rest or moving at a constant speed.

Front

What is an unbalanced force?

Back

An unbalanced force causes a change in the motion of an object, such as starting, stopping, or changing direction.
