1st Semester Final Exam Review of MOTION

Front

What is Newton's First Law of Motion?

Back

An object in motion stays in motion and an object at rest stays at rest unless acted on by an outside force.

Front

What does Newton's Second Law of Motion state?

Back

Force equals mass times acceleration (F = ma).

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

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 acceleration?

Back

The greater the mass of an object, the less acceleration it will have when a given force is applied.

Front

What is the formula for calculating force?

Back

Force = mass x acceleration (F = ma).

Front

What is an example of Newton's First Law in everyday life?

Back

A soccer ball continues to roll on the ground until friction or another force stops it.

Front

What is an example of Newton's Second Law in action?

Back

A heavier object requires more force to move than a lighter object when pushed.

Front

What is an example of Newton's Third Law in action?

Back

When you jump off a small boat, the boat moves backward as you move forward.
