Energy Transfer and Conservation

Front

What is thermal (heat) energy?

Back

Thermal (heat) energy is the energy associated with the motion of particles in a substance.

Front

What happens to potential energy when a roller coaster goes downhill?

Back

Potential energy is converted into kinetic energy.

Front

What is the difference between potential energy and kinetic energy?

Back

Potential energy is stored energy, while kinetic energy is the energy an object has due to its motion.

Front

What type of energy does a generator convert mechanical energy into?

Back

A generator converts mechanical energy into electrical energy.

Front

How does thermal (heat) energy transfer occur?

Back

Thermal (heat) energy always moves from hotter objects to cooler objects.

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 stored energy that has the potential to do work.

Front

Can energy be created or destroyed?

Back

No, energy cannot be created or destroyed; it can only be transformed from one form to another.

Front

What is an example of energy transformation?

Back

When a light bulb converts electrical energy into light energy.

Front

What is mechanical energy?

Back

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