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 happens to an object when equal force is applied to it?

Back

The object will accelerate in the direction of the force, depending on its mass.

Front

Why is it important to conduct multiple trials in an experiment?

Back

To ensure the results are reliable and can be repeated.

Front

What is a variable in an experiment?

Back

A factor that can change and affect the outcome of the experiment.

Front

What is the purpose of a spring scale?

Back

To measure the amount of force applied to an object.

Front

What does it mean to test one variable at a time?

Back

To change only one factor in an experiment to see its effect on the outcome.

Front

What is the effect of a rough surface on friction?

Back

A rough surface increases friction, making it harder for objects to slide over it.

Front

How does mass affect the motion of an object?

Back

More mass means more force is needed to move the object.
