1

work done

work done = force x distance

2

kinetic energy

kinetic energy = 1/2 x mass x speed^2

3

GPE

GPE = mass x height x gravity

4

power

power = work done/time

5

efficiency

efficiency = useful output / input

6

charge

charge = current x time

7

potential difference

potential difference = current x resistance

8

power

power = potential difference x current

9

current

current = resistance x potential difference

10

energy transferred

energy transferred = charge flow x potential difference

11

density

density = mass / volume

12

moment

moment = force x distance

13

distance

distance = speed x time

14

acceleration

acceleration = change in velocity/ time taken

15

weight

mass x gravity

16

force

force = spring constant x extension mass x acceleration

17

momentum

momentum = mass x velocity

18

pressure

pressure = force/area

19

wave speed

wave speed = frequency x wavelength
