Weight (N) = mass (kg) * gravitational field strength (N/kg)
Work done (J) = force (N) * distance (m)
Force (N) = spring constant (N/m) * extension (m)
Elastic potential energy (J) = 1/2 * spring constant (N/m) * extension (m)2
Moment of a force (Nm) = force (N) * distance (m)
Pressure (Pa) = force (N) / area (m2)
Pressure (Pa) = height (m) * density (kg/m3) * gravitational field strength (N/kg) Distance (m) = speed (m/s) * time (s) Acceleration (m/s2) = change in velocity (m/s) / time (s)
Final velocity (m/s)2 - initial velocity (m/s)2 = 2 * acceleration (m/s2) * distance (m)
Resulutant force (N) = mass (kg) * acceleration(m/s2)
Momentum (kg m/ s) = mass (kg) * velocity (m/s)
Force (N) = change in momentum (kg m/s) / change in time (s)
