Front

Define Mechanical Energy.

Back

The sum of potential energy and kinetic energy in an object.

Front

What is Potential Energy?

Back

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

Front

What is Kinetic Energy?

Back

The energy an object possesses due to its motion.

Front

State the formula for Kinetic Energy.

Back

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

Front

State the formula for Potential Energy.

Back

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