Question

Is momentum a scalar or vector?

Answer 1

Explanation:

1. Scalar quantities often referred to as scalars, are physical quantities that have only magnitude and no direction. An integer, combined with the appropriate units, can represent a scalar quantity.
2. Furthermore, the term "vector" refers to a physical quantity that has both magnitude and direction and obeys the vector addition laws. A number with a unit and a direction is used to describe a vector quantity.
3. A body's (or a moving body's) momentum is calculated by multiplying its mass by its speed. $P$ stands for it.
4. The formula for calculating a body's momentum is $P=mv$, where $m$ stands for the mass and $v$ for the object's velocity. The amount of matter in a body with no clear shape is measured by its mass. Mass is a scalar quantity since it only has magnitude.
5. The rate at which an object's position changes over time in a particular direction is known as its velocity. It can also be described as an object's speed moving in a specific direction. It is the distance traveled in one unit of time. Velocity is a vector quantity since it has both magnitude and direction.
   We are aware that a vector quantity is produced when a scalar quantity and a vector quantity are multiplied together.
6. Since it is the result of multiplying a body's mass, a scalar quantity, by its velocity, a vector, momentum is a vector quantity.

Hence, momentum is a vector quantity.
