Question

a body is constraint to move only y-direction under the action of a force = -2i +15J +6k N if the body moves a distance of 10m then the work done is = ?​

Answer 1

Answer:

Explanation:First of all, work (W)  isn’t force multiplied by distance, it’s force (F) multiplied by displacement (s).

So, W= F*s  

  And as for why is the equation so, it is because work is done only when the object changes its original position.

  As an object can only change its position when a certain force is applied, whether it be muscular or magnetic or gravitational.

  As Work is completely dependent on both these factors, we conclude that:

  W= F*s
