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 work in physics?

Back

Work is done when a force causes an object to move in the direction of the force.

Front

What is a mixture?

Back

A combination of two or more substances that are not chemically bonded and can be separated.

Front

What is friction?

Back

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

Front

What is the role of a spring scale?

Back

A device used to measure the force exerted on an object, typically in newtons.

Front

How does mass affect the force needed to move an object?

Back

Greater mass requires more force to move the object due to inertia.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the difference between pushing and pulling?

Back

Pushing moves an object away from you, while pulling brings it closer.

Front

What is the effect of surface texture on friction?

Back

Rough surfaces create more friction than smooth surfaces, requiring more force to move an object.

Front

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

Back

It helps ensure the results are reliable and reduces the impact of errors.
