Front

What does Newton's 1st Law of Motion state?

Back

An object in motion will stay in motion until an outside force acts upon it.

What is an example of Newton's 3rd Law of Motion?

Back

A rocket launching into space.

Front

What happens to a rock's acceleration as it tumbles down a hill?

Back

It will increase.

Front

Why is it important to consider both mass and force when analyzing an object's motion?

Back

Because the object's change in motion depends on both mass and force.

Front

What is motion?

Back

The change in position of an object over time.

Front

What is gravity?

Back

A force that pulls objects toward each other, like the Earth pulling us down.

Front

What is friction?

Back

A force that opposes motion between two surfaces in contact.

Front

What is inertia?

Back

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

Front

What is acceleration?

Back

The rate at which an object's velocity changes over time.
