in closed path intial and final distance is same i,e change in distance=0 so work done in closed path is zero
Work is done in lifting is equal to work done in opposing gravity. Work done in opposing gravity = weight times distance = 700 x 4 =2800 joules
Work is force times displacement (distance). Thus, about 3 work is being done. The unit depends on the unit of the work and distance. If the work unit is Joules, and the distance unit is meters, then the force unit would be Newtons.
You are supposed to multiply force x distance.
Work=Force+Distance =joule

1 half km = 500m 1687m-500m=1187m

what kind of oil for a sears push mower and how much?
You have only done as much external work on the box as the distance it moves: work = force x distance. If it does not budge no work is done on the object. You have done "internal" work on your muscles which converts to heat energy, but technically speaking, no external work is done on the object
force=2N distance moved=o.1 m work done=? work done=force(N)*distance moved (M) work done=2*o.1 work done= 0.2 watts
in closed path intial and final distance is same i,e change in distance=0 so work done in closed path is zero
Depends on the size of the mower.
Depends on how good their doing. I would say about 500M-700M
That will vary for each make and model of mower.
it depends on size and location some big ones will cost around 300m to 500m
