Force and Motion Test

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 when it comes in contact with another surface.

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 Newton's 2nd Law of Motion?

Back

The acceleration of an object depends on the mass of the object and the amount of force applied (F=ma).

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is the effect of mass on force?

Back

The greater the mass of an object, the more force is needed to move it.

Front

What happens when two forces are equal and opposite?

Back

They cancel each other out, resulting in no movement.

Front

What is the role of gravity in motion?

Back

Gravity pulls objects toward the Earth, affecting their motion.

Front

How does surface texture affect friction?

Back

Rough surfaces create more friction than smooth surfaces.
