Conservation of Energy

Question 1

what is energy?

Answer 1

energy is the ability to do work

Question 2

what is kinetic energy?

Answer 2

Kinetic energy is the energy an object has while it is moving.

Question 3

Another name for kinetic energy?

Answer 3

movement energy

Question 4

what is heat energy??

Answer 4

energy that passes from a hot object to a cooler one

Question 5

what is potential energy?

Answer 5

stored energy that can be released to do work

Question 6

gravitational potential energy

Answer 6

when an object is raised from the ground it has gravitational potential energy, when released it turns into kinetic energy.

Question 7

what 3 thing does gravitational potential energy depends on

Answer 7

mass, its height from earth and force of gravity.

Question 8

chemical potential energy

Answer 8

energy that is released when burnt

Question 9

elastic potential energy

Answer 9

when an object returns to its original form after being stretched it is elastic, potential energy is stored when the elastic is being stretched.

Question 10

what is light energy

Answer 10

energy that gives us the ability to see

Question 11

what is sound energy

Answer 11

sound energy is energy that is carried through materials by sound waves

Question 12

what is electrical energy?

Answer 12

moving electrons in a conductor

Question 13

what is nuclear energy

Answer 13

a form of potential energy stored in nuclei of some atoms.

Question 14

Types of potential energy

Answer 14

gravitational potential energy
chemical potential energy
elastic potential energy
nuclear energy

Question 15

Units of energy

Answer 15

joules (J)
kilojoules (KJ)

Question 16

Equation of energy

Answer 16

1000 J =1KJ
3000 J / 1000 = 3KJ

Question 17

The law of conservation

Answer 17

energy is neither created nor destroyed but can be converted from one form to another
