### What is Momentum?

In physics, momentum is defined as the product of an object's velocity and mass. It's a vector quantity and its unit of measurement is a kilogramme meter per second. To put it another way, it's the mass of an item in motion. Linear momentum and rotational momentum are the two types of momentum. It is used to anticipate the speed and direction of the objects after they meet because it has both magnitude and direction. As a result, the formula for calculating momentum is as follows

Momentum = Mass x Velocity i.e. p = m x v

When momentum and velocity are known, the formula for calculating mass is m = p / v

When the mass and momentum of an object are known, the formula for calculating velocity is v = p / m

• Where, m = mass of an object
• v = speed of a moving object
• p = momentum of an object

### How to Calculate the Momentum of an Object?

The mass of an object in motion is defined as its momentum. A few steps following will help you simplify the momentum. The following basic procedures will show you how to solve an object's momentum.

• To begin, calculate the object's mass and velocity using the information provided in the question.
• Multiply the object's mass and velocity.
• The result is known as object momentum.

### How to Use the Momentum Calculator?

The following procedure explains how to use the momentum calculator

• In the input field, enter the unknown's mass, velocity, and x.
• To acquire the result, click the "Calculate the Unknown" button.
• Finally, in the output field, the object's momentum will be displayed.

### Real-Life Examples of Momentum

• A karate practitioner, with his fist, can create enough speed to drive the momentum through many bricks, smashing them.
• Two football players of equal mass are travelling at the same speed, one at 4 m/sec and the other at 7 m/sec towards each other. The one going at a quicker speed has more momentum and will push the other one backwards.
• Due to modest mass, a four-wheeler travels at a comparably rapid speed because it has less momentum than a semi-truck and will stop considerably faster.
• Despite its little mass, a bullet possesses considerable momentum due to its incredibly high velocity.

### Examples on Finding Momentum

Question 1: A body with a mass of 6 kg is travelling at a speed of 20 m/s. Calculate the body's momentum?

Solution:

Given: m = 6 kg, v = 20 m/s, p = ?

Now, the formula for calculating momentum is

p = m X v = 6 x 20 = 120 kg m/s.

Question 2: The momentum and velocity of an object are 85 kgm/s and 20 m/s, respectively. Determine the mass of an object?

Solution:

Given: m = ?, v = 20m/s, p = 85 kgm/s

Now, the formula for calculating momentum is

p = m X v

Rearranging for mass we have m = p/v = 85/20 = 4.25kg

### FAQs on Momentum Calculator

1. What is the best way to find final momentum?

Final momentum is the product of the final velocity and mass of an object. If the body's final velocity is zero, the body's final momentum is also zero.

2. Is there a sense of direction to Momentum?

It gives both the direction and the magnitude because it is a vector quantity. As momentum is derived from mass and velocity, it always points in the direction of velocity.

3. What's the difference between momentum and force?

In general, momentum denotes the amount of mass in motion, whereas force denotes the amount that alters the amount of motion. Momentum is defined as the quantity of motion that surrounds a moving object.

4. How do you calculate combined momentum?

Because the two colliding objects proceed in the same direction after colliding, the momentum can be computed by multiplying the total mass of the objects by their velocities.

5. After a collision, how do you calculate final momentum?

Divide the mass of the second object by the velocity of the second object. If it weighs 1,000 kilogrammes and travels at a speed of -30 metres per second, its momentum is 30,000 kilogrammes per second. To find out which way the items will go after colliding, add the two velocities together.
