Energy Transformation

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as from chemical energy to mechanical energy.

Back

Chemical energy to mechanical energy.

Front

What does gravitational potential energy depend on?

Back

Gravitational potential energy depends on the height and mass of the object.

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

Back

Position X.

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

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

Front

What is the formula for gravitational potential energy?

Back

Gravitational potential energy = mass × gravity × height (PE = mgh).

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object.
