Question

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

Answer 1

Hey Shati

Yes, An object can have momentum even If its mechanical energy is zero.


It's because:

[] Mechanical energy is 0 due to the net energy taken 

[] So, the body may posses kinetic energy

[] ∴ It will have momentum if there's kinetic energy... 



Thanks

Answer 2

YES , it is possible that object have momentum even If its mechanical energy is zero

Explanation:

since ,

Mechanical energy is the sum of potential energy and the Kinetic energy

i.e '

ME = PE + KE

if ME = 0

then

PE + KE = 0

PE = - KE

thus ,

it has some kinetic energy it means the body have momentum

hence ,

The body have momentum even If its mechanical energy is zero.
