Speed = m/s (meters per second)
Acceleration = m/s^2 (meters per second squared)
Gravity = m/s (meters per second) (free fall), M/s^2 (meters per second squared) (acceleration due to gravity), N/kg (newtons per kilogram) (weight) Resultant force = N (newtons)
Density = m^3 (meters cubed)
Weight = N (newtons)
Force = N (newtons)
Pressure = pa (1Pascal = 1n/m^2)
Work = j (joules)
P.E = j (joules)
K.E = j (joules)
Stopping distance =m
Efficiency = j (joules) and %
Power = W (watts)
Useful power = W (watts)
Frequency = Hz (hertz)
Period = s (seconds)
Amplitude = m (meters)

Wave length = m (meters)
Speed of sound = (approx.) air: 330m/s, liquid: 1,500m/s, Solid: 5,000m/s
Speed of light in a vacuum = 3,000,00 km/s (3,000,000 m/s)
Density of water = 1.0g/ cm^3 Density of aluminium = 2.7g/ cm^3 Density of copper = 8.9g/ cm^3 Density of lead = 11.4g/ cm^3 Density of mercury = 13.6 g/cm^3 Density of gold = 19.3g/ cm^3
