Question

If a body falls from a height, the relation between
its kinetic and potential energies is:
A. Gain in K.E = Loss in P.E. - Work done
against friction
B. Gain in P.E = Loss in K.E. + Work done
against friction
C. Loss in K.E = Gain in P.E. + Work done
against friction
D. Loss in P.E = Gain in K.E. - Work done
against friction​

Answer 1

Answer:

Option D

Loss in P. E = gain in K. E - work done against friction
