**Formula used**
$p=mv$

## What is momentum

The momentum, p of an object is defined as the product of its mass, m and velocity, v

$p=mv$

Where

p -> Momentum

m -> Mass of the object

v -> Velocity of the object

Momentum has both direction and magnitude so it is a vector quantity. Its direction is the same as that of velocity

The SI unit of momentum is kilogram-meter per second

**Example of Few questions where you can use this Momentum Calculator**

**Question 1**

A Body of mass 4 kg is moving with the velocity 10 m/s.Calculate the momentum of the body

**Solution**

Given m=5 kg, v=10 m/s, p=?

Now Momentum is defined by the formula

$p=mv = 5 \times 10 = 50 \ kg-m/s$

**Question 2**

A body of mass 2 kg has momentum of 10 kgm/s .Find the velocity of the body.

**Solution**

Given m=2 kg, v=?, p=10 kgm/s

Now Momentum is defined by the formula

$p=mv $

Rearranging for Velocity

$v= \frac {p}{m} = \frac {10}{2} = 5 \ m/s$

**Question 3**

A object has momentum and velocity as 75 kgm/s and 10 m/s .Find the mass of the object.

**Solution**

Given m=?, v=10m/s, p=75 kgm/s

Now Momentum is defined by the formula

$p=mv $

Rearranging for Mass

$m= \frac {p}{v} = \frac {75}{10} = 7.5 \ m$

## How the Linear Momentum Calculator works

1. If mass and velocity given

$p=mv$

2. If mass and momentum are given

$v= \frac {p}{m}$

3. If velocity and Momentum are given

$m = \frac {p}{v}$
