Kinetic energy equation: Ek=1/2 mv2

Momentum equation: p=mv

Kinetic energy equation in terms of momentum: Ek = p2/2m

The kinetic energy of the two objects will be the same if their mass and momentum are the same. Among light and heavy bodies, the Heavy body has the highest momentum. When the momentum is the equal light body has more kinetic energy.
