  # The SI Unit of Momentum is

By BYJU'S Exam Prep

Updated on: September 25th, 2023 Kilogram meter per second is the SI unit of Momentum. It is the product of the mass and velocity of an object. It possesses a magnitude and a direction hence it is a vector quantity.

Table of content ## Answer: The SI unit of Momentum is kilogram meter per second. It is represented as kg⋅m/s.

The SI unit of Momentum is equivalent to the newton-second. The formula to determine the momentum of an object is p = mv where p is momentum, m is the mass of the object and v is the velocity of the object. The direction of momentum is the same as that of velocity.

### Three Laws of Motion

There are three laws of motion. Each one of them has been elucidated below.

• First Law of Motion: It states that the motion of objects on an inclined plane moves with a constant speed when no force acts on them.

• Second Law of Motion: It states that the rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of the force.

• Third Law of Motion: It implies that when one object exerts a force on another object, the second object instantaneously exerts a force back on the first.

Summary:

## The SI Unit of Momentum is

The SI unit of momentum is kg⋅m/s. It depends on the frame of reference. Its dimension is MLT−1. GradeStack Learning Pvt. Ltd.Windsor IT Park, Tower - A, 2nd Floor, Sector 125, Noida, Uttar Pradesh 201303 help@byjusexamprep.com
