प्रश्न
Can any object have momentum even if its mechanical energy is zero? Explain
Advertisements
उत्तर
No, if mechanical energy = kinetic energy + potential
energy = 0,
So, potential energy = kinetic energy = 0
or `1/2"mv"^2` = 0 or v = 0
So, momentum, p = mv = 0
Any object can not have momentum even if
its mechanical energy is zero.
