lesson 6- types of energy

Question 1

chemical energy

Answer 1

potential energy stored in chemical bonds of compound
(e.g. food you eat contains chemical energy that powers the body)

Question 2

electrical energy and magnetism

Answer 2

work done by moving charges, electricity produces magnetic fields
(e.g. batteries show a relationship between electric and chemical energy)

Question 2

nuclear energy

Answer 2

potential energy stored in the nucleus of an atom

Question 3

nuclear fission

Answer 3

single nucleus being split into two smaller nuclei

Question 4

nuclear fusion

Answer 4

two small nuclei combining to form large nucleus

Question 5

solar energy

Answer 5

released nuclear energy from the sun

Question 6

kinetic energy

Answer 6

energy from motion, any object in motion has ability to do work

Question 7

gravitational potential energy

Answer 7

an object raised above earth’s surface has potential to do work bc of its position

Question 8

mechanical energy

Answer 8

energy associated with motion and position of an object

Question 9

thermal energy

Answer 9

heat flows from hot to cold

Question 10

can we convert heat and mechanical energy to one another?

Answer 10

yeah
