Question

Can any object have momentum even if its mechanical energy is zero? Explain.

Answer 1

Explanation:

1. Kinetic energy is $0$, velocity is also zero.
2. If the mechanical energy of an item is zero, it cannot have momentum.
3. As a result, there will be no forward motion.
4. Momentum is mass in motion, and any moving object can have momentum.

Mechanical Energy = Potential energy + Kinetic Energy
$\mathrm{M}.\mathrm{E}=0$
So,

$\mathrm{K}.\mathrm{E}+\mathrm{P}.\mathrm{E}=0$
$\mathrm{P}.\mathrm{E}=-\mathrm{K}.\mathrm{E}$

No. There is no potential energy or kinetic energy since mechanical energy is zero.
