Question

A body of mass 10kg falls to the ground from a height 1km. If all energy is converted to heat,find the amount of heat developed?​

Answer 1

Answer:

We know that total energy of a body is always constant according to the principle of conservation of energy.

So, energy possessed by the body at any instant = initial potential energy of the body.

mgh= 10 × 9.8 × 1

= 98.
