What is the distance which the force is multiplied by it to get the work done?
a) The distance of the body motion while the force was touching it?
b) The total distance of the body motion?
How can you calculate the work if the body was moving with some initial speed then a force acted on this moving body while it was moving.
How can we calculate the work done if the distance the body moved is not caused directly by the force which was acting on the body?
