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, and more.

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as electrical energy to thermal energy.

Front

What type of energy is associated with motion?

Back

Kinetic energy is the energy of motion.

Front

What type of energy is stored in an object due to its position?

Back

Potential energy is the stored energy in an object due to its position or state.

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 an object.

Front

What is radiant energy?

Back

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

Front

What type of energy transformation occurs in a microwave oven?

Back

In a microwave oven, electrical energy is transformed into thermal energy (heat) and radiant energy (microwaves).

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 a device that transforms electrical energy into mechanical energy?

Back

A fan is an example of a device that transforms electrical energy into mechanical energy.

Front

What energy transformation occurs in a battery-operated radio?

Back

In a battery-operated radio, the energy transformation is from chemical energy to electrical energy to sound energy.
