## What is Impulse

Impulse is defined as the the product of force and the time during which the force acts. It is a vector quantity as Force is vector quantity, Its unit is Newton-sec. It is denoted by Letter I. So, I is defined as
$I= F \times t$
Where
I -> Impulse
F -> Force acting on it
t -> time during which force is being applied
Impulse is also calculated as the difference from Final momentum and initial Momentum
$I= p_2 - p_1 = mv_2 - mv_1$ Where m -> mass
$v_2$ -> Final velocity
$v_1$ -> Initial velocity

## Impulse Calculator using change in momentum

Note
• Enter the values of the mass , initial velocity and final velocity in the text boxes
• Click on the calculate button.

Formula used
$I =p_2 - p_1$
$I=mv_2 - mv_1$
Where m -> mass
$v_2$ -> Final velocity
$v_1$ -> Initial velocity

### Impulse Calculator

Example of Few questions where you can use this Impulse formula
Question 1
Calculate the Initial Momentum,Final Momentum and Impulse on the object have mass 10 kg and initial and final velocites as 10m/s and 20 m/s
Solution
Given , m= 10 kg, $v_1 = 10 \ m/s$, $v_2 = 20 \ m/s$
• Initial Momentum ($p_1$) is calculated as
