4.PS3.3 Changing Energy

Front

What is energy?

Back

Energy is the ability to do work or cause change. It can exist in different forms, such as kinetic or potential energy.

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 that has the potential to do work. It depends on the position or condition of an object.

Front

What is electric energy?

Back

Electric energy is the energy that comes from electric charges. It powers devices like toasters, lights, and computers.

Front

What is solar energy?

Back

Solar energy is energy from the sun. It can be converted into electricity or heat.

Front

What is wind energy?

Back

Wind energy is the energy generated from the movement of air. Wind turbines convert this energy into electricity.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of an object. It is the total kinetic energy of particles in a substance.

Front

How does energy change form?

Back

Energy can change from one form to another, such as potential energy converting to kinetic energy when an object falls.

Front

What happens to energy in a toaster?

Back

In a toaster, electric energy is converted into thermal energy to heat and toast the bread.

Front

What is an example of changing energy?

Back

An example of changing energy is a roller coaster. As it climbs, it has potential energy, and as it descends, that energy changes to kinetic energy.
