Energy and Energy Transformation

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, and chemical.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It increases with the speed of the 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 roller coaster at the top of a hill has potential energy.

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 chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like batteries or food.

Front

What is radiant energy?

Back

Radiant energy is the energy of electromagnetic waves, such as light. It is the form of energy that travels through space.

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 nuclear energy?

Back

Nuclear energy is the potential energy stored in the nucleus of an atom, which can be released during nuclear reactions.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is the relationship between speed and kinetic energy?

Back

As the speed of an object increases, its kinetic energy also increases.
