Units are in red.Velocity = Distance/Time m/sSpeed=Distance/Time m/s or mphAcceleration=Change in velocity/Time m/s2)Force (N) =Mass x Acceleration NForce=k (spring constant) x elasticity. NPressure (S&G) = force/area Pa (1 Pa = 1 N per square metre.)Density= mass / volume g/cm3 or kg/cm3Pressure (Liquids) = density x depth x 9.8 or 10. PaVoltage = I x R VKey definitions: Ductile- Can be stretched into a thin wire, e.g. CopperMalleable- Won't break during shaping exercises.
