Question

if an object has zero Momentum does it have kinetic energy explain your answer

Answer 1

Let an object have zero momentum. So, according to momentum formula,

Mass(m) * volume(v) = 0

There are two cases:- Either mass=0 or velocity=0

Mass cannot be zero.So, only velocity can be zero.

Velocity is zero(0).

Since, the velocity is 0 we can infer that the object is at rest.

We know that, kinetic energy is the energy possessed by the body when it is motion.

Kinetic energy= 1/2*m*v^2

Kinetic energy= 1/2*m*0

=> Kinetic energy= 0

Therefore, we can conclude that an object having 0 momentum would have 0 kinetic energy.

Hope it helps.

Answer 2

No the body will not have kinetic energy.......
momentum=mv^2.....k.e=1/mv^3....if momentum is zero the ke will also be 0
