Time seconds (s)
Length meters (m)
Mass kilograms (kg)
Velocity v = Dd/Dt (m/s)
Acceleration a = Dv/Dt (m/s2)
Force F = ma (N) = kgm/s2
Pressure P = F/area (Pa) = N/m2 = kg/ms2
Work W = Fd (J) = kgm2/s2
Potential Energy PE = Ug = mgh (J) = kgm2/s2
Kinetic Energy K = ½ mv2 (J) = kgm2/s2
Power P = W/t (W) = kgm2/s3
