1

Weight

Weight = mass x gravitational field strength

2

Work done

Work done =force x distance

3

Force applied to a spring

Force applied to a spring = spring constant x extention

4

Moment

Moment = force x distance

5

Pressure

Pressure = force / area

6

Distance traveled

Distance traveled = speed x time

7

Accelaration

Accelaration = change in velocity / time taken

8

Resultant force

Resultant force = mass x acceleration

9

Momentum

Momentum = mass x velocity

10

Kinetic energy

Kinetic energy = 0.5 x mass x velocity squared

11

Gravitational potential energy

Gravitational potential energy = gravitational field strength x height x mass

12

Power (energy)

Power = Energy transferred / time

13

Power (work)

Power = work done / time

14

Efficiency

Efficiency = useful output / total input

15

Wave speed

Wave speed = frequency x wavelength

16

Charge flow

Charge flow = current x time

17

Potential difference

Potential difference = current x resistance

18

Power (circuits)

Power = potential difference x current

19

Power (circuits without voltage)

Power = resistance x current squared

20

Energy transferred

Energy transferred = power x time

21

Energy transferred (circuits)

Energy transferred = charge flow x potential difference

22

Density

Density = mass / volume
