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

A force that opposes the motion of an object when it comes into contact with another surface.

Front

What factors affect the amount of friction between two surfaces?

Back

The texture of the surfaces and the weight of the objects in contact.

Front

What is a spring scale used for?

Back

To measure the amount of force applied to an object.

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 an object's motion when a force is applied?

Back

The object may start moving, stop moving, or change direction.

Front

What is the relationship between mass and force?

Back

Heavier objects require more force to move than lighter objects.

Front

What is the effect of a rough surface on motion?

Back

It increases friction, making it harder for objects to move.

Front

How does the type of shoe affect the amount of force required to pull it?

Back

Different shoe materials and designs create varying levels of friction.
