Forces and Motion PreAssessment

Front

Define inertia.

Back

Inertia is the tendency of a moving object to continue moving or a stationary object to remain at rest.

Front

What does friction oppose?

Back

Friction is a force that opposes motion.

Front

How does mass affect inertia?

Back

Mass affects an object's inertia by increasing it.

Front

What property of matter keeps an object in motion unless acted upon by an external force?

Back

Inertia.

Front

Which has more inertia: a refrigerator or a ping pong ball?

Back

A refrigerator has more inertia.

Front

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is the definition of force?

Back

A force is a push or pull on an object that can cause it to accelerate.

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 an external force.

Front

What is an example of inertia in everyday life?

Back

A passenger lurching forward in a car when it suddenly stops.

Front

What is the effect of friction on motion?

Back

Friction slows down or stops the motion of an object.
