Force and Motion STAAR Review

Front

What is force?

Back

A force is a push or pull on an object that can cause it to move, stop, or change direction.

Front

What is motion?

Back

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

Front

What is friction?

Back

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

Front

What happens when equal force is applied to different objects?

Back

The object with less mass will generally move farther than the object with more mass, assuming friction is the same.

Front

What is the effect of a rough surface on motion?

Back

A rough surface increases friction, which can slow down or stop moving objects.

Front

What is the relationship between mass and friction?

Back

Heavier objects tend to have more friction with the surface they are on, which can affect their motion.

Front

How can you improve an experimental investigation?

Back

Using the same conditions for all trials, such as the same object or surface, helps ensure fair testing.

Front

What can a force do to an object?

Back

A force can make an object move, slow it down, or stop it.

Front

What is an example of a force in everyday life?

Back

Pushing a shopping cart or pulling a suitcase are examples of forces in action.

Front

What is the importance of using the same object in experiments?

Back

Using the same object helps to isolate the variable being tested, making results more reliable.
