Force and Motion STAAR Review

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

The force that opposes the motion of two surfaces in contact.

Front

What factors affect the distance an object travels when a force is applied?

Back

The mass of the object and the amount of force applied.

Front

What is the relationship between mass and motion?

Back

Heavier objects require more force to move the same distance as lighter objects.

Front

What is a variable in an experiment?

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

To accurately determine the effect of that variable on the outcome.

Front

What is a constant force?

Back

A force that remains the same throughout an experiment.

Front

How does surface texture affect friction?

Back

Rough surfaces create more friction than smooth surfaces.

Front

What is gravitational force?

Back

The force that pulls objects toward each other, such as the Earth pulling objects toward its center.
