Question
Can a body have energy without momentum or vice-versa? Explain.
Solution
It is possible for a body to have energy without momentum.
For example, a body at rest in gravitational field possesses the potential energy.
That is, the potential energy stored in stretched spring.
But the body cannot have momentum without energy because if the body has momentum, it also possesses the kinetic energy.
