Question

can a body have momentum when its energy is negative ? Give example to explain your answer.

Answer 1

if the energy of a body is negative then momentum of body is imaginary.
E= p²/2m
for negative energy
-E = p²/2m
p=(√2mE)i
so momentum is imaginary..

1. a body always has a internal energy
2. it has momentum implies it has velocity implies it has kinetic energy
