1.	Is walking a work?If yes,what kind of work?
Answer» ANSWER: Your muscles do some work when you start to get you up to walking speed. According to physics there is no work being done once you get up to a constant speed. At a constant speed there is no acceleration, no force, and no work. Unfortunately, just because you aren't doing any work doesn't mean your muscles aren't consuming any energy, muscles are inefficient like that. When you are climbing up a hill or a ladder you are doing work in a physical SENSE, since you are fighting gravity trying to PULL you down. Your muscles then have to consume EXTRA energy, some of it ends up doing work to make you go up and some gets wasted in your muscles.
