Question

(7) State the
con under which the work
done is positive on negative zero

Why is the work done on an object mos
with uniform circular motion zero?​

Answer 1

Answer:

$\huge{ \bold{ \purple{ \star{answer}}}}$

We saw that when the force and displacement are in the same direction, we call the work as positive.

In the opposite direction, we call the work as negative.

The work is stated as zero when there is no displacement of any given object along a line of force.

Work done on an object is the product of force applied and the displacement covered in the direction of force applied. ... Hence, the work done in a uniform circular motion is always zero.
