Question

Perform the activities as illustrated in Fig. Record your observations. The examples in the figure are self-illustrated to tell you that work done on an object directly depends

(i) on the force applied, and

(ii) the distance through which an object moves.

More force is needed to move an object (through a distance) of large mass than an object of small mass. More work is done by a bigger force.

Answer 1

The work done on an object depends on:

1. Force applied: More force is needed to move a heavy box, so more work is done.
2. Distance moved: More work is done when the object moves through a greater distance.

Thus,

W = F × s

Therefore, work done directly depends on the force applied and the distance through which the object moves.
