Answer 1

magnetic
thermal
chemical
kinetic
electrostatic
elastic potential
gravitational potential
nuclear

Question 2

magnetic description

Answer 2

The energy stored when repelling poles have been pushed closer together or when attracting poles have been pulled further apart.

Question 3

magnetic examples

Answer 3

Fridge magnets, compasses, maglev trains which use magnetic levitation.

Question 4

thermal description

Answer 4

The total kinetic and potential energy of the particles in an object, in most cases this is the vibrations - also known as the kinetic energy - of particles. In hotter objects, the particles have more internal energy and vibrate faster.

Question 5

thermal examples

Answer 5

Human bodies, hot coffees, stoves or hobs. Ice particles vibrate slower, but still have energy.

Question 6

chemical description

Answer 6

The energy stored in chemical bonds, such as those between molecules.

Question 7

chemical examples

Answer 7

Foods, muscles, electrical cells.

Question 8

kinetic description

Answer 8

The energy of a moving object.

Question 9

kinetic examples

Answer 9

Runners, buses, comets.

Question 10

electrostatic description

Answer 10

The energy stored when repelling charges have been moved closer together or when attracting charges have been pulled further apart.

Question 11

electrostatic examples

Answer 11

Thunderclouds, Van De Graaff generators.

Question 12

elastic potential description

Answer 12

The energy stored when an object is stretched or squashed.

Question 13

elastic potential examples

Answer 13

Drawn catapults, compressed springs, inflated balloons

Question 14

gravitational potential description

Answer 14

The energy of an object at height.

Question 15

gravitational potential examples

Answer 15

Aeroplanes, kites, mugs on a table.

Question 16

nuclear description

Answer 16

The energy stored in the nucleus of an atom.

Question 17

nuclar examples

Answer 17

Uranium nuclear power, nuclear reactors.
