Back

The change in position of an object over time.

Front

What is friction?

A force that opposes the motion of an object, caused by the contact between two surfaces.

Front

What is gravity?

Back

A force that pulls objects toward each other, such as the pull of the Earth on objects.

Front

What is mass?

Back

The amount of matter in an object, usually measured in grams or kilograms.

Back

A factor that can change in an experiment, affecting the outcome.

Front

Why is it important to test one variable at a time in an experiment?

Back

It allows the experimenter to correctly and more easily interpret the results.

Front

What happens to the motion of an object when a greater force is applied?

Back

The object will accelerate more and move faster.

Front

How does mass affect the distance an object travels when a constant force is applied?

Back

Heavier objects may not travel as far due to increased friction.
