body can have energy without momentum.. but it must have mass... without mass no energy., and body cannot have momentum without energy.....

a body can have energy without having moment and body shoul be of some mas..........for example a boook on the shelf it posses potential energy but since it is at rest it not have momentum...............................but abody cant have momentum without energy if we place the same buk on ground then book posses none of momentum and energy bcoz its on ground and have u=0.......................u can illustrate the same with debroglies equation if the body not have energy its momentum will not be defined

yes,body can have energy without momentum buersely is not conversely is not true..energy is neede to gain velocity and hence there can be momentum

yes a body can have energy without momentum like potential energy........... it is the inherent energy of a body due to its configuration.......
