Forms of Energy and Energy Transformation

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 or transferred from one form to another.

What is energy?

Back

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

Front

What is kinetic energy?

Back

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

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 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

How does a windmill transform energy?

Back

A windmill transforms mechanical energy from the wind into electrical energy.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons. It is used to power devices and appliances.

Front

What is an example of energy transformation in a hairdryer?

Back

A hairdryer transforms electrical energy into thermal energy to heat the air.

Front

What is mechanical energy?

Back

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

Front

What is an example of thermal energy transfer?

Back

When you touch a hot stove, thermal energy is transferred from the stove to your hand.
