Does look wrong doesnt it? But it isnt (based on the figures above (assuming Jonnos can actually do 3,500rpm)

It has to be remembered that KE is proportional to the SQUARE of velocity. (KE=1/2MV^2)

Unlike Momentum which is directly proportional to velocity (P=MV)

Since Kinetic Energy is proportional to the Square of the Velocity, this means that a Mass traveling at 2 metres per second has 4 times the Kinetic Energy of the Same Mass travelling at 1 Metre per second, Even though it only has double the momentum.

Perhaps measurements should be compared in terms of momentum (Kgm/s) and not Kinetic Energy (KJ)?

Anyone please feel free to correct me on any of this, I am by no means skilled in this field.
