Question

An object is dropped from a height H. when is its
(i)    P.E. maximum,
(ii)    K.E. maximum,
(iii)    P.E. = K.E.?

Answer 1

(i) At the height H because the height is maximum.
(ii) At the ground level because the velocity is maximum.
(iii) At half distance of the total path i.e. at height H/2, the P.E. is equal to the K.E.
