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

Dec 10, 2015

The 6 kg object has more momentum.

#### Explanation:

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

$P = m \times v$

So for the 1st object:

$P = 6 \times 7 = 42 {\text{ "kg.m.s}}^{- 1}$

For the 2nd object:

$P = 3 \times 5 = 15 {\text{ "kg.m.s}}^{- 1}$
