Question

How does the momentum of a large object compare to that of a small object if they are at the same velocity?

Answer 1

The momentum of a fast object compared to that of a slow object even if they both have the same velocity, is their masses.

Having same velocity but different masses results in different momentum.

Example: velocity = 20 m/s
Mass 1 = 10 Mass 2 = 50
Momentum 1 = 10×20 = 200 Ns
Momentum 2 = 50×20 = 1000 Ns
