Momentum Formula

Overview of 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 one can 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 to Calculate Momentum?

Newton’s Laws of Motion says that all the bodies that are in a state of motion or at rest, continue to be in that position till such times when they are being interfered with, or by some external force.  In order to get the formula to find momentum, the same principle is used.  

If the velocity and the mass of any particular object remain unchanged, then we will see no change in the momentum of the object.  

Equation for Momentum

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.  

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

FAQs (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.

4. Define Momentum?

Momentum is another measurement of the vector, where the Momentum and the velocity are both in the same direction.

The simple meaning of momentum is mass in motion and is associated with the mass of a moving body. The quantity of motion is measured as a product of the mass and the velocity. The product of the units of mass and velocity is the unit of Momentum. To find the momentum, we can use the simple formula: P=mv, where P is the momentum.

5. What is the Formula of Momentum?

According to the Formula of Momentum, it is said that momentum is very closely associated with the entire mass that a moving body has. This is the motion quantity and It is measured by creating the product of the velocity and the mass of the moving body.  Momentum is also known as the measurement of a vector. The direction of Velocity and momentum remains the same. Therefore, the formula can be written only when we know about the velocity and the mass of the body. 

5. How do you calculate momentum?

According to the Laws of Motion as stated by Newton, all the bodies which are in a state of motion or rest, continue to be in that position till the time they are being interfered with by some sort of external force. This is the same principle that we are going to use in order to get the formula to find momentum. Let us take the example here: 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. A  very simple formula that can be used in order to find out the momentum of any object.
