Can any object have momentum even if its mechanical energy is 0? explain.
yes i can explain this theoritically as
let a body has both P.E and K.E & P.E = - K.E . then totol mechanical energy =K.E +P.E =0
but momentum is there as body is having some velocity in this case
but i am not sure if it is practically possible or not as there is no such example striking me right now
Total Energy = K.E. + P.E.
K.E.: 1/2mv^2m is not 0. v is not 0. therefore mv (momentum is not 0) and as a whole K.E.: is not 0.P.E.: mgh m cannot be 0. g cannot be 0. h can be 0. As a whole, the value of P.E.: cannot be determined but since K.E. is not 0 then Total Energy cannot be 0.
An object can have mechanical energy even if it's momentum is 0.
K.E.: 0P.E.: mgh (same happens here but we consider that h has a value of more than 0)
Therefore, T.E. is not 0 in both cases
The answer is "No" , because for an object to have momentum (mass * velocity) the object has to have a certain velocity. If an object has a velocity 'v' then the object also has a Kinetic energy = 1/2*m*v^2 .
