Back

The object's speed increases.

Front

Back

A force that pulls objects toward each other, such as the pull of the Earth on objects.

Front

What is the relationship between mass and force?

Back

The greater the mass of an object, the more force is required to move it.

Front

What is a balanced force?

Back

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

Front

What is an unbalanced force?

Back

Forces that are not equal, causing a change in motion of an object.
