Question

Work done by a body occurred when ________

A) the body shows displacement in the opposite direction of the force applied.
B) the body shows a displacement in the same direction as that of the force applied.
C) the body shows a displacement in the perpendicular direction to the force applied.
D) the body masses obliquely to the direction of the force applied.​

Answer 1

Work done by a body occurs when the body shows displacement in the same direction as the force applied.

Step-by-step explanation:

Work done by a body occurs when the body shows displacement in the same direction as the force applied. In other words, if the force and the displacement are parallel, work is done. For example, if you push a box across a table, the force you exert is in the same direction as the displacement of the box, so work is being done. On the other hand, if the force and the displacement are perpendicular or in opposite directions, no work is done. For instance, if you push against a wall, the force you apply is perpendicular to the displacement of the wall, so no work is being done.
