Work

Well work is done when a force causes a chnge in the position or the motion of an object. An example of work would be pushing a car by hand. Power, is the rate at which work is done. The more power you have in pushing the car the faster you will get it moving. Mechanical adantages are the ratio between the output for force and the input force. A mechanical adavantage could help you push the car. Ive learned a lot about work and what makes up work.
