Can any object have mechaincal energy even if it momentum is zero ? Exaplain.

Text Solution

Verified by Experts

No. If mechanical energy is zero, both potential and kinetic energies are zero. Since kinetic energy is zero, `(1)/(2)m upsilon^2 = 0, i.e., upsilon = 0,` which means momentum `(p =m upsilon)` is also zero.
