Question

Can a body have energy without having momentum ? Explain?

Answer 1

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.
