Momentum can be difficult to explain, but to put it simply, it is the rate at which mass moves when it is in motion. This is a fundamental and crucial principle for our universe and plays a role in every single object, essentially.

How do you Calculate Momentum?

Momentum can be calculated with a couple of variables:

  • Mass

  • Velocity

Once you have the values for these variables you can use this formula to calculate momentum:

Understanding Your Results

Your momentum result will be displayed as a single number result that is shown as pound feet per second by default, but can be converted into various other units with the click of a button. For example, if you have an answer of 75 pound feet per second, you can then select feet per minute from the dropdown and your answer will be converted to match that unit, which would be 2,041.164.

How to Use the Momentum Tool

Using a tool like ours to calculate momentum is designed to help you save time and effort. You can easily find the momentum of an object with this tool in a few steps. The steps include:

  1. Enter the mass of the object.

  2. Enter the velocity at which the object is moving.

  3. Ensure that each of the units for the fields are correct and align with your values you are entering.

  4. Hit calculate and get the momentum of the object instantly!

Example Calculation

Let's say you want to investigate how much momentum your car has when you are driving. Your car weighs about 3,500 pounds and you are driving 65 miles per hour. You can enter these values in this tool to get your momentum answer. First we will enter the mass of the vehicle, then we will enter 65 into the velocity field and change the unit to be miles per hour.

We can now hit calculate and get our answer of 9,080,911.84 feet per minute. We can change the unit of measurement to another unit by selecting it from the dropdown menu and it will automatically convert your answer to the new unit.

Momentum - Frequently Asked Questions

They are similar concepts but are not the same. Impulse is more like the measure of the effect of a force acting on an object for a period of time.

Momentum is often denoted by the letter p. This can be confusing since p is in no way related to the word momentum.

Yes, there are situations where momentum can be negative.

Yes, an object will have zero momentum if its mass or velocity is zero.

Yes, objects in space are still capable of having momentum despite experiencing different conditions.

Momentum would actually be the same on the moon and here on Earth. Both are based on velocity and mass. An object still has its mass on the moon and can move at the same velocity, so they are the same.
