# Does a boy in rest have momentum?

Jul 1, 2018

Well, technically yes... and no.

#### Explanation:

Momentum is given by the equation:

$p = m v$

where:

• $p$ is the momentum of the object

• $m$ is the mass of the object

• $v$ is the velocity of the object

Since the boy's at rest, his velocity is $0$, and his momentum is therefore $p = m \cdot 0 = 0$ as well.

We can say in physics that the boy has no momentum. However, in a philosophical sense, we could also claim that yes, the boy has momentum, but its value is $0$.

So, in my opinion, the answer depends on which way you're thinking from.
