Weight 
Weight N = Mass kg x gravity N/kg 

Work done 
Work done J or Nm = force N x distance m 

Force applied to a spring 
Force applied to a spring N = spring constant N/m x extention m 

Moment of a force 
Moment of a force Nm = force N x distance m 

Force normal to a surface 
Force normal to a surface N = pressure Pa x area m2 

Distance travelled 
Distance travelled m = speed m/s x time s 

Change in velocity 
Change in velocity m/s = acceleration m/s2 x time taken s 

Resultant force 
Resultant force N = mass kg x acceleration m/s2 

Momentum 
Momentum kg m/s = mass kg x velocity m/s 

Kinetic energy 
Kinetic energy J = 0.5 x mass kg x speed2 m/s 

Gravitational potential energy 
Gravitational potential energy J = mass kg x gravitational field strength N/kg x height m 

Energy transferred 
Energy transferred kWh = time h x power kW 

Work done (in a circuit) 
Work done J = time s x power kW 

Wave speed 
Wave speed m/s = frequency Hz x wavelength m 

Charge flow 
Charge flow C = current A x time s 

Voltage 
Voltage V = current A x resistance O 

Power 
Power kW = current2 A x resistance O 

Energy transferred 
Energy transferred kWh = power kW x time h 

Energy transferred (in circuit) 
Energy transferred J = charge flow C x voltage V 

Mass 
Mass kg = density kg/m3 x volume m3 

Pressure in liquid 
Pressure Pa = height m x density of liquid kg m3 x gravity N/kg 

SUVAT 
(V velocity m/s) 2  (u velocity m/s) 2 = 2 x accel m/s2 x distance m 

Change in momentum 
Change in momentum kg m/s = time s x force N 

Elastic potential energy 
Elastic potential energy J = 0.5 x spring constant N/m x extension2 m 

1 
1 = Period ? x frequency Hz 

Power (definantly in circuit) 
Power kW = current A x voltage V
