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
