Energy and Energy Transformations

Front

What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, such as kinetic, potential, thermal, chemical, and more.

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 potential energy?

Back

Potential energy is stored energy based on an object's position or state. For example, a rock at the top of a hill has gravitational potential energy.

Front

What is sound energy?

Back

Sound energy is caused by the vibrations of particles in a medium (like air, water, or solids). It travels in waves.

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 during a chemical reaction.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance. It is related to temperature and heat.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is an example of energy transformation?

Back

An example of energy transformation is when a battery (chemical energy) powers a flashlight (light energy).

Front

What is mechanical energy?

Back

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

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons. It powers devices like lights and computers.
