Energy Transformations Review

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 a substance.

Front

What is Kinetic Energy?

Back

Kinetic energy is the energy of an object due to its motion. It depends on the mass and velocity of the object.

Front

What is Sound Energy?

Back

Sound energy is a form of energy that is associated with the vibration of matter. It is produced when an object vibrates and creates sound waves.

Front

What is Electrical Energy?

Back

Electrical energy is the energy caused by the movement of electrons. It can be converted into other forms of energy, such as thermal or mechanical energy.

Front

What is Chemical Energy?

Back

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

Front

What is Mechanical Energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object. It is the energy associated with the motion and position of an object.

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 held at a height has gravitational potential energy.

Front

How does a battery convert energy?

Back

A battery converts chemical energy into electrical energy, allowing it to power devices.
