How much work is done when a force of 1 N moves a body through a distance of 1m in its own direction?
work=force×displacement
work=1N×1m
work=1J
(a) When do we say that work is done? Write the formula for the work done by a body in moving up against gravity. Give the meaning of each symbol which occurs in it.
(b) How much work is done when a force of 2 N moves a body through a distance of 10 cm in the direction of force?
A force of 20 N displaces a body through a distance of 1 m at an angle of 60° from its own direction. Calculate the amount of work done.
