This is what I got from my text. Can you provide me with some examples because I am a bit confused. Can you provide some explanation?

Is this true for angular momentum?

Consider two particles with mass m, one with velocity +v and one with velocity -v.

So momentum is zero and kinetic E is not zero. Can you give an example for kinetic energy zero and momentum non zero?Consider two particles with mass m, one with velocity +v and one with velocity -v.

KE = sum of 1/2 mvSo momentum is zero and kinetic E is not zero. Can you give an example for kinetic energy zero and momentum non zero?

Or, imagine covering the whole system with a curtain or box and treating it as one object of total mass M and velocity V.

P=MV, while KE= 1/2MV

If KE = 0, what does that imply? Assume masses are never negative.

I understood. Thanks @Vanadium 50 and @Cruikshank.
