If we examine the motion of an ice hockey puck, after being hit, it can maintain its velocity without further help for a very long way indeed. The commonality of these two examples is the lack of friction, and therefore a lack of force on th ...

... The job of MOST machines is to decrease the amount of force you have to use to perform a specific task. A car jack allows you to lift up a car without you exerting a large amount of force to do it. The amount of work to do a job never changes whether you use a machine or not. So if force decreases ...
