1

## distance

### distance = speed x time

2

## acceleration

### a = (v-u) / t

3

## weight

### w = mass x gravity or N = kg * N/kg

4

## momentum

### momentum (p) = mass x velocity

5

## gravitational potential energy

### gpe = m * g * h

6

## kinetic energy

### (1/2mass) x v^2

7

## efficiency

### efficiency = useful energy/ total energy

8

## wave speed (velocity) involving frequency

### v = f * wavelength

9

## wave speed (velocity) involving time

### v = x/t

10

## final velocity^2 - start velocity^2

### v^2 - u^2 = 2ax (2 x acceleration x distance)

11

## force

### f=ma

12

## advanced force

### f= (mv - mu) / t

13

## power/watts

### p = e/t

14

## work

### J = force x distance
