Question

if an object has 0 momentum, does it have kinetic energy? explain your answer

Answer 1

For a secluded body if force is zero and kinetic energy is zero since force, mv = 0 infers active vitality, (1/2)*mv^2 = (1/2)*mv*v=0.

In any case, for two indistinguishable perfect objects pushing straightforwardly toward each other, each with a similar MAGNITUDE of force. Since they are moving, they have active vitality. The aggregate motor vitality is the sum of the two. Since the momenta are "equivalent, however, inverse", the aggregate of momenta is zero.

Momentum has direction(vector) however motor vitality does not(scalar).

Answer 2

Hey!!
Here is your answer..

Yes, It has a kinetic energy.

We know that,
Momentum = mass × change in velocity.

Kinetic energy=

Thus,
Momentum = 0 when change in velocity is zero.
But, kinetic energy can never be 0 even if it is in motion.

✔️Momentum is a vector Quantity.
That is it has both magnitude and direction.
✔️ Kinetic energy is a scalar quantity.
That is it has only magnitude and no direction.
Hence, If an object has 0 momentum, it always have kinetic energy.

This is the answer .
I hope it helps you.
