In the last few week of physics we have been talking about work and energy and when it is applied. Work is the process of moving an object by applying a force, so if we are pushing someone and they end up falling in that direction then you are applying work to them. When I think of work and applying a force I think of a weight lifter and how much force they have to apply to the weights to be able to life them. If a weight lifter is lifting a 100 kg weight and their displacement is 2 meters the work being done is 1962 Joules. For a force to have done work on an object it must have caused a displacement, the weights had originally been on the ground and were raised two meters. Weight lifters use a lot of work and energy to be able to lift their weights.
