A mass m is dropped from a height h. At halfway to the ground its total energy is-

Question

Is it mgh? (law of conservation of energy)

Answer 1

Explanation:

When we are at maximum height h, potential energy is maximum and kinetic energy is zero.

PE = mgh

Now, according to conservation of energy, the energy at all the points is same along the line of motion.

Answer :

Thus, at midway also, the total energy is mgh.
