Energy and Energy Transformations

Front

What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, including kinetic, potential, thermal, chemical, electrical, and radiant.

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 are energy transformations?

Back

Energy transformations are processes in which energy changes from one form to another, such as chemical energy to electrical energy.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules.

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 electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons through a conductor.

Front

What is radiant energy?

Back

Radiant energy is the energy of electromagnetic waves, including light.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically related to its height.

Front

How does a flashlight transform energy?

Back

A flashlight transforms chemical energy from batteries into electrical energy, which is then converted into radiant energy (light) when the flashlight is turned on.

Front

What energy transformation occurs in a lamp?

Back

In a lamp, electrical energy is transformed into light energy.
