Question

Work is done on an object when

A) The displacement is not zero
B) The force and the displacement are perpendicular
C) The displacement is zero
D) The force is zero

Answer 1

Incomplete question but the closest ans is

A) The displacement is not zero

Step-by-step explanation:

For work to be done, the direction of force has to be parallel to or in the same direction as the displacement, this can then be calculated by

`W=Fs \ cos`θ

Where θ is the angle between direction of force and direction of displacement

By this equation,

if Force is zero, W is zero

if displacement is zero, W is zero

if force and displacement are perpendicular θ=90, cosθ = 0

So A is the cloest choices
