Front

What is the formula for calculating kinetic energy?

Back

KE = 1/2 mv² (where m is mass and v is velocity)

Front

What is the formula for calculating potential energy?

Back

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

Front

How does height affect potential energy?

Back

Potential energy increases as height increases.
