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 potential energy?

Back

Potential energy is the energy stored in an object due to its position or state.

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)
