Work, is done when a force causes a change in the position or motion of an object. Example of work would be trying push a wall over by hand. Power, is the rate at which work is done. The more power you have in pushing the wall over the faster it will go down. Mechanical Advantages is the ration between the out put for force and the input force. Mechanical advantages would be the machines you could you to help you push the wall over. I learned a lot about what is actually put into your work and all the thing that you need to have work.
