Impulse Calculator

Enter the total mass of an object (m) and the change in velocity of that object to calculate its impulse. This calculator converts mass and speed into the impulse, which is another word for the change in momentum.

Impulse Formula

The following formula can be used to calculate Impulse:

Impulse = (m) * (V2-V1)

  • M is the mass (kg)
  • V2 is the final velocity (m/s)
  • V1 is the initial velocity

Now lets compare this to the formula for momentum. Momentum = mass (m) * velocity (v)As you can see, they are nearly identical, except impulse has a change in velocity.

Impulse Definition

Impulse is a term used in mechanics and physics to describe the net change in moment of an object or system.

How to calculate impulse?

So how do you use this calculator? First you need to obtain the mass of an object. You can do this through calculation or through the use of a scale. Next, you need to measure the speed or velocity at a start point and an end point. Then, you need to subtract the last measured speed by the first measured speed. Finally, multiply your change in speed by the mass that you had weighed early. Now you have your impulse. Another way to calculate impulse is to calculate the momentum at the initial time, and the final time. Then subtract momentum 1 from momentum 2 and you are your impulse.

FAQ

What is impulse?

Impulse is a term used in mechanics to describe the change in momentum of an object.

What is momentum?

Momentum is a product of the mass and velocity of an object. The faster and heavier an object is, the more momentum it contains.
