Physics for IGCSE & O level - Forces And Motion (Section 10 - No. 8)
If two objects of different masses have the same kinetic energy, which one will have a greater momentum?
The object with the larger mass.
The object with the smaller mass.
They will have the same momentum.
You cannot determine momentum from kinetic energy.

Momentum depends on mass and velocity. If kinetic energy is the same but mass is greater, the heavier object must be going faster.
