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 into contact with another surface.

Front

What is acceleration?

Back

The rate at which an object changes its velocity, which can be an increase or decrease in speed.

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 is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What happens when two forces of equal strength act in opposite directions?

Back

The object will not move at all.

Front

How does mass affect acceleration?

Back

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

Front

What is the effect of surface texture on friction?

Back

Rough surfaces create more friction than smooth surfaces.
