I W PE mgh Solution. P I 2 R. W mgh 20 x -98 x 10 -1960J The work done to take an object of mass 20 kg to a height of 10 m is -1960 J.
Suppose a tractor-pulled a wagon full of hay to a distance of 1000 m. In many occasions we need to calculate the amount of work done by an object in motion. Force F 5 N Dist.
Work formula is made use of to compute work done force or displacement in any problem. The work done by an object can be calculated if we know the force applied to the object and the displacement of the object. Therefore the work done by gravity is 490 J.
