# When a body falls, its momentum increases. Does this mean that the momentum is not conserved?

See below.

#### Explanation:

Note that calling $p = m v$ then $\frac{\mathrm{dp}}{\mathrm{dt}} = f$ or

the momentum variation equals the sum of external actuating forces. If a body is falling under gravity then $f = m g$
