Force and Motion STAAR Review

Front

What type of force is created when rubbing your hands together?

Back

Friction is the force created when two surfaces rub against each other.

Front

Why do heavier objects experience more friction when pushed?

Back

Heavier objects have increased friction with the floor due to their weight.

Front

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

Back

Testing one variable at a time allows for clearer interpretation of results.

Front

What is the benefit of conducting multiple trials in an experiment?

Back

Multiple trials make the results more reliable.

Front

What type of surface creates more friction when an object moves against it?

Back

A rough surface creates more friction.

Front

What is force?

Back

Force is a push or pull on an object.

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is gravity?

Back

Gravity is the force that pulls objects toward each other, such as the Earth pulling us down.

Front

What is the relationship between force and motion?

Back

Force causes an object to move or change its motion.
