The distance an object travels per unit of time.

Front

What is acceleration?

The rate at which an object changes its velocity.

Front

What is a balanced force?

Back

Forces that are equal in size and 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.

Front

What is a simple machine?

Back

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