What is 'wasted energy' in energy transformations?

Back

Wasted energy is energy that is not useful for the intended purpose, often released as heat.

Front

What type of energy is associated with motion?

Back

Kinetic energy is the energy of motion.

At which position does a roller coaster cart have the most gravitational potential energy?

Back

The roller coaster cart has the most gravitational potential energy at the highest point, position W.

Front

What is potential energy?

Back

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

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion.
