Different types of energy

Question 1

The main stores of energy are:

Answer 1

Kinetic
Gravitational potential
Chemical
Elastic potential
Nuclear
Internal
Thermal

Question 2

What is internal energy?

Answer 2

The amount of energy in an object’s internal energy is the sum (total) of the kinetic energy and potential energy stored in the object’s particles.

Question 3

Components of an object’s internal store:

Answer 3

kinetic store

potential store

Question 4

What property of an object is a measure of the energy in the kinetic stores of its particles?

Answer 4

The temperature of a body (object) is a measure of the energy in the kinetic stores of its particles.

Question 5

internal energy is the total of the ____ store and the ____ energy stored in an objects particles

Answer 5

The amount of energy in an object’s internal energy is the sum (total) of the kinetic energy and potential energy stored in the object’s particles.

Question 6

gravitational potential energy is:

Answer 6

the energy stored due to an objects position above the ground.

Question 7

kinetic energy is:

Answer 7

the energy stored in a moving object

Question 8

Elastic potential energy is:

Answer 8

the energy stored in a stretched spring

Question 9

thermal energy is:

Answer 9

the energy stored due to an objects temperature

Question 10

What does the law of conservation of energy state?

Answer 10

Energy can be transferred usefully, stored or dissipated but cannot be created or destroyed.

Question 11

What is a system?

What is a closed system?

Answer 11

A system is an object or a group of objects

A closed system means that no energy can enter or leave.
