CP3A Energy stores and transfers

Question 1

What are all the ways energy can be stored

Answer 1

Magnetic
Thermal
Chemical
Kinetic energy
Electrostatic
Elastic potential energy
Gravitational potential energy
Nuclear energy

Question 2

What is magnetic energy with an example

Answer 2

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

Question 3

What is thermal energy

Answer 3

Energy in hot objects e.g human body

Question 4

What is chemical energy

Answer 4

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

Question 5

What is kinetic energy

Answer 5

The energy of a moving object e.g bus

Question 6

What is electrostatic energy

Answer 6

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

Question 7

Elastic potential

Answer 7

The energy stored when an object is stretched or squashed e.g drawn catapults

Question 8

What is gravitational potential energy

Answer 8

The energy of an object at height e.g aeroplanes

Question 9

What is nuclear energy

Answer 9

The energy stored in the nucleus of an atom e.g nuclear reactors

Question 10

What is the law of conservation

Answer 10

Energy cannot be created or destroyed. It can only be transferred from one store to another
