1

Distance travelled

= average speed x time

2

Acceleration

= (final velocity - inital velocity) ÷ time

3

Force

= mass x acceleration
OR
= spring constant x extension

4

Weight

= mass x gravitational field strength

5

Efficiency

= useful energy in ÷ time

6

Gravitational Potention Energy

= mass x gravitational field strength x distance

7

Kinetic Energy

= 1/2 x mass x velocity^2

8

Momentum

= mass x velocity

9

Wave velocity

= frequency x wavelength

10

Velocity

= distance ÷ time

11

Work done

= force x distance moved in direction of force

12

Power

= energy transferred ÷ time
OR
= current^2 x resistance
OR
= current x potential difference

13

Moment

= force x distance normal to the direction of the force

14

Energy transferred

= charge x potential difference

15

Potential difference

= current x resistance

16

Charge

= current x time

17

Density

= mass ÷ volume

18

Pressure

= force ÷ area
