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

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

Back

To make the results more reliable.

Front

What happens to an object when a constant force is applied?

Back

It will accelerate in the direction of the force.

Front

What is gravity?

Back

A force that pulls objects toward each other, such as the Earth pulling objects toward its center.

Front

How does mass affect motion?

Back

More massive objects require more force to move the same distance as less massive objects.

Front

What is a simple machine?

Back

A device that makes work easier by allowing us to push or pull over increased distances.

Front

What is the relationship between force and motion?

Back

Force causes motion; without force, an object at rest will stay at rest.

Front

What is a balanced force?

Back

Forces that are equal in size but opposite in direction, resulting in no change in motion.
