Light and heavy objects have equal kinetic energy.which one has greater momentum?
Generally, for kinetic energy
For larger mass
So the larger mass has greater momentum
Thing to note is that momentum is a vector quantity so here we are looking at absolutes values of momentum. A mass with -ve velocity (and momentum) always has "smaller" momentum than any other mass with +ve velocity, simply due to the sign, but that might defeat the purpose of the question.
