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?

why does it take more and more energy to accelerate it the same amount?
Because you also need to accelerate the energy you've put in.
