Understanding the Concepts

* Momentum (p): A measure of an object's motion. It's calculated as mass times velocity: p = mv

* Mass (m): The amount of matter in an object.

* Speed (v): The rate at which an object is moving (the magnitude of its velocity).

The Formula

To find speed (v) from momentum (p) and mass (m), you can rearrange the momentum equation:

```

p = mv

v = p / m

```

Example

Let's say you have an object with:

* Momentum (p) = 20 kg*m/s

* Mass (m) = 5 kg

To find the speed (v):

* v = p / m

* v = 20 kg*m/s / 5 kg

* v = 4 m/s

Therefore, the speed of the object is 4 meters per second.
