Energy and Energy Transformations

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as converting chemical energy in batteries to electrical energy in a flashlight.

Front

What are the main forms of energy?

Back

The main forms of energy include kinetic, potential, thermal, chemical, electrical, radiant, and nuclear 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 energy transformation occurs when a flashlight is turned on?

Back

The energy transformation is from chemical energy (in batteries) to electrical energy to radiant energy (light).

Front

Which form of energy is NOT produced by a lamp?

Back

Chemical energy is NOT produced by a lamp; it primarily produces radiant (light) and thermal (heat) energy.

Front

What device transforms electrical energy into mechanical energy?

Back

A fan transforms electrical energy into mechanical energy.

Front

What type of energy is stored in food?

Back

Chemical energy is stored in food.

Front

What is radiant energy?

Back

Radiant energy is the energy of electromagnetic waves, including visible light, infrared, and ultraviolet radiation.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object, enabling it to do work.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, related to the motion of particles.
