Potential vs Potential Difference: Key concept for O and A level physics Electricity topics


So I give you a very simple example – we have a 2kg box
resting on a frictionless surface and I exert a force of 5N over 2m Calculating the acceleration…. *calculating noises* Using kinematics equations to calculate final speed.. *more
calculation noises* Determining the final KE using the final velocity we
calculated earlier…. Notice that the gain in Kinetic energy is 10 Joules, which is equal to the work done on the object box! (5N x 2
m)! Hence we can think of work done as the amount of energy that
we have transferred to the object!
