Energy Types 01
Moving energy is kinetic energy.

Energy Types 01

Energy exists in many types, such as heat, light, sound, and movement. In KS3 Science, pupils study how energy changes form while following conservation rules.

Fascinating Fact:

Energy cannot be created or destroyed, only changed from one type to another.

In KS3 Science, pupils explore different types of energy such as kinetic, thermal, and electrical. They also learn the principle of conservation of energy and how it applies to real life.

  • Kinetic Energy: The energy of movement, such as a rolling ball or a moving car.
  • Thermal Energy: The energy of heat that makes particles vibrate faster.
  • Conservation of Energy: The idea that energy cannot be created or destroyed, only transferred or transformed.
What are the main types of energy in KS3 Science?

The main types of energy include kinetic, thermal, light, sound, chemical, electrical, and gravitational potential energy.

What does conservation of energy mean?

Conservation of energy means energy cannot be created or destroyed. It only changes form, such as chemical energy in food becoming kinetic energy when you move.

Why is learning about energy types important?

Learning about energy helps pupils understand how machines, living things, and natural systems work, and how to use resources more efficiently.

1 .
The main types of energy released by a burning candle are:
light and sound
light and thermal
thermal and chemical
thermal and sound
Thermal and heat energy are the same
2 .
The unit of energy is:
a coulomb
a degree
a joule
a newton
It was named after physicist J.P. Joule (1818-1889)
3 .
Which of the following is NOT a type of energy?
Heat
Potential
Temperature
Thermal
A change in temperature of an object tells you if it is gaining or losing thermal energy
4 .
Useful energy that flows along a wire is:
chemical
electrical
light
thermal
Can you imagine life without electrical energy?
5 .
Which type of energy is stored energy in a stretched rubber band?
Chemical
Elastic
Kinetic
Thermal
Also called elastic potential energy
6 .
Which type of energy is stored energy due to gravity?
Chemical
Kinetic
Potential
Thermal
If you move an object from one shelf to a higher shelf, it will have more potential energy due to gravity
7 .
The main type of energy released by a coiled spring is:
chemical
elastic
kinetic
potential
It moves!
8 .
Which type of energy is moving energy?
Chemical
Kinetic
Potential
Thermal
If two objects have the same mass, the one that is moving faster will have more kinetic energy
9 .
Which type of energy is stored in a battery?
Chemical
Electrical
Kinetic
Light
Hope you weren't tempted by electrical!
10 .
Which type of energy is given out by a luminous object?
Kinetic
Light
Potential
Sound
This is often achieved by making an object very hot but not always - a glow worm uses a chemical reaction to produce light
