The amount of work you do varies person to person, or person to hamster. You do work on an object when you move it. Work is the process of moving an object by applying a force. If I push my hamster, Pepper, 3 meters and apply a force of 2 newtons, then the work I did is 6 joules, since work is force multiplied by displacement. However when I apply the force of 2 newtons to pepper and she moves, it doesnâ€™t seem like she is impacting me, however she is also applying a force of two newtons back on me. When you do work you transfer energy from one object to another therefore I am transferring my energy to Pepper the hamster.
