Front

The ability to do work or cause a change describes what?

Back

Energy.

Front

What is kinetic energy?

Back

The energy an object possesses due to its motion.

Front

What is potential energy?

Back

The energy stored in an object due to its position or state.

Front

What is the formula for kinetic energy?

Back

KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for potential energy?

Back

PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What happens to energy in a closed system?

Back

The total energy remains constant; it can change forms but is not lost.
