Effect of Driving and Braking Force Torque.
Torque is ‘the turning effect of a Force’. It is the vector product of an applied Force and the Distance over which the Force is applied. ‘Vector’ simply means that the product of the quantities takes account of their direction, as well as their size. The units of Torque (Newton metres) are derived from the units of Force (Newtons) multiplied by the units of Distance (metres). Most people are familiar with distance being measured in metres, however, the unit of Force -the Newton- is less familiar. It may help to consider that a Force of ‘1 Newton’ is approximately the weight of an apple.
