Amplify Force and Motion Unit Review

Front

What happens to a stationary object if no force is applied?

Back

The object will remain stationary.

Front

What direction must a force come from in order to stop a moving object?

Back

The force must come from the opposite direction as the object's motion.

Front

In a collision, if one object experiences a stronger force, what can be inferred about the other object?

Back

The other object experienced a weaker force or the same force, depending on the context.

Front

What is the relationship between force and motion?

Back

Force causes an object to accelerate, change direction, or stop.

Front

Define 'force'.

Back

A push or pull on an object that can cause it to change its velocity.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does mass affect the force needed to accelerate an object?

Back

Greater mass requires more force to achieve the same acceleration.

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 effect of balanced forces on an object?

Back

Balanced forces do not change the motion of an object.

Front

What is the effect of unbalanced forces on an object?

Back

Unbalanced forces cause an object to accelerate in the direction of the net force.
