Front

What is the formula for kinetic energy?

Back

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

Front

What are electromagnetic waves?

Back

Waves that can travel through a vacuum and do not require a medium.

Front

What is the law of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.
