(b) Can a body have momentum without having energy? Explain.

Answer 1

Answer:

A body near the earth surface have acceleration of gravity g

Hence, if (height from earth surface) h<<<R

e

(Radius of earth)

even in a rest state, when momentum is zero,

Body still have potential energy, U=mgh (where, m= mass of body).

Hence, it is possible to have energy without having momentum.
