What is Chemical Energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules. It is released during a chemical reaction, often in the form of heat.

Where is the stored energy of a roller coaster cart the greatest?

Back

The stored energy of a roller coaster cart is greatest when it is resting at the top of the hill.

Front

What type of energy does a paper airplane flying 50 feet above the ground have the most of?

Back

Potential energy, because it is at a higher elevation.

Front

What is Electrical Energy?

Back

Electrical energy is the energy caused by the movement of electrons. It powers devices like TVs and phones.

Front

What causes Sound Energy?

Back

Sound energy is caused by vibrations and travels in waves.

Front

What is Thermal Energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of particles in an object.

Front

What is Mechanical Energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object that is used to do work.

Front

What is Potential Energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a rock at the top of a hill has potential energy.

Front

What is Kinetic Energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

What is the relationship between height and potential energy?

Back

The higher an object is, the more potential energy it has due to gravity.
