Overview of Momentum And What is The Formula of Change in Momentum

In this section, you will be able to learn more about the Momentum formula and how to use this particular formula to solve some of the most important questions in the exam. Momentum is a really important topic for the students and they definitely need to be aware of the formula. This section deals with the exact formula for momentum and it also tells you about the change in momentum and how can one calculate it. 


How to Calculate Momentum 

One of the most important topics that students seem to focus on is the momentum formula physics. So, we are going to provide some information on that. According to the Laws of Motion as denoted by Newton, all the bodies that are in a state of motion or rest, continue to be in that position until and unless they are being interfered with by some sort of an external force. Now, this is the same principle that we are going to use in order to get the formula to find momentum. For example, if the velocity and the mass of a particular object remain unchanged, then there will be no change in the momentum of the object as well. This is a very simple formula that students can use in order to find out the momentum of any object. 


How Do You Write The Formula of Momentum? 

Before you know all about the formula for momentum, it is important to define it. As per its definition, it can be said that momentum is very closely associated with the entire mass that a moving body has. This can actually be defined as the motion quantity. It is measured by creating the product of the velocity and the mass of the moving body. Momentum can also be called the measurement of a vector. The direction of Velocity and momentum remains the same. So, the formula can be written only when we know about the velocity and the mass of the body. 


What is the Equation for Momentum 

If you want to know what is the formula of change in momentum then we are going to provide you with a very simple solution right here. As we know the formula for momentum is given as: 

p=mv

Where,

p can be denoted as the momentum that a body has,

m can be denoted as the mass that the body has

and v can be denoted as the velocity that the body has.

This is a very simple equation and it will definitely answer your question on how to find momentum. It will also help you to know that the S.I unit for momentum can be termed as Kg ms-1.


FAQ (Frequently Asked Questions)

1. What is the change in the momentum formula?

When there is a change in the momentum of the object, it is generally caused due to the change in the velocity of the object. So, in order to find out the change in the momentum formula, it is important to find the product of the mass of the moving body with the change in its velocity. So, the formula can be given as: 

Δp=m⋅(Δv)=m⋅(vf−vi).

vf and vi can be denoted as the final and the initial velocities. It is important to use proper signs when there is a change in velocities. This is the way the students can know how to calculate momentum.

2. What is the change in momentum formula force?

The change in momentum formula force can be derived like this: 

We know 

F=dp/dt

3. How do I find momentum?

In order to find momentum all you have to do is use the simple formula of

P=mv where P is the momentum. It is a very simple formula to understand.
