Question

Which has more momentum, a `6kg` object moving at `7m/s` or a `3kg` object moving at `5m/s`?

Answer 1

The 6 kg object has more momentum.

Explanation:

You work out the momentum `P` of an object by multiplying the mass by the velocity:

`P=mxxv`

So for the 1st object:

`P=6xx7=42" "kg.m.s"^(-1)`

For the 2nd object:

`P=3xx5=15" "kg.m.s"^(-1)`
