Force and Motion Review

Front

What is air resistance?

Back

Friction in the air that slows things down.

Front

What is the formula for calculating force?

Back

Force = mass x acceleration (F = m x a).

Front

What does Newton's 3rd Law of Motion state?

Back

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

Front

What does a curved line on a distance-time graph indicate?

Back

That the speed is changing.

Front

Why is it more difficult to move a dresser full of clothes than an empty dresser?

Back

Due to Newton's 2nd Law of Motion, which states that force equals mass times acceleration.

Front

What is the definition of force?

Back

A push or pull on an object resulting from the object's interaction with another object.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the relationship between mass and acceleration according to Newton's 2nd Law?

Back

An increase in mass results in a decrease in acceleration if the force is constant.

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N).

Front

What does a flat line on a distance-time graph represent?

Back

An object at rest.
