Answer this.

Object 1, M=1, V=4, Ke=8, P=4
Object 2, M=2, V=2, Ke=4, P=4
Object 3, M=4, V=1, Ke=2, P=4
Object 4, M=1, V=2, Ke=2, P=2
Object 5, M=0.125, V=4, Ke=2, P=0.5

Why does it take more energy to give a mass the same momentum as a larger mass?

Object1, M=1
V=1, P=1, Ke=0.5
V=2, P=2, Ke=2
V=3, P=3, Ke=4.5

When an object is accelerating without resistance, why does it take more and more energy to accelerate it the same amount?

#2 oh I guess I didn't really answer what you asked, I have to figure that out.
