Question

I work done on a body equal to
change in its -
a) KE
b) P E
c) K. E or P. E
d) none​

Answer 1

Answer:

you are doing work against inertia, such that the work equals the change in kinetic energy of the object. When you are doing work against continuous resistive forces, such as gravity or spring tension, work done equals the change in potential energy of the object.

And therefore you can opt for (C)
