- Forces and Motion Equations
- speed = distance/time
- s = d/t

- force = mass x acceleration
- F = ma

- acceleration = change in velocity/time
- a = v-u/t
- v = final velocity
- u = initial velocity

- v = final velocity

- a = v-u/t
- weight(N) = mass(kg) x gravitational field strength(N/kg)
- w = mg

- momentum = mass x velocity
- p = mv

- change in momentum = force x time
- (mv-mu) = Ft

- density = mass/volume
- d = m/v

- pressure = force/area
- p = F/a

- moment = force x perpendicular distance from pivot
- m = Fd

- speed = distance/time
