Question

What is the formula for calculating momentum ?

Answer 1

Hint: The amount of motion that occurs in something that is moving, or the force that propels something forward to keep it moving, is known as momentum. The rate at which a vehicle descends a hill is an indicator of momentum.

Complete answer:
The product of mass and velocity is known as momentum. Two kinds of momentums exist, which are:
Linear Momentum:
The product of an object's mass, $m$, and velocity, $v$, is known as Linear Momentum. It is a conserved quantity, meaning that a system's overall momentum remains unchanged. As the definition suggests, the formula of Linear momentum is:
$p = m \times v$
Here, $p$ is the linear momentum, $m$ is the mass of the object and $v$ is the velocity of the object.

Angular Momentum:
The product of a body's rotational inertia and rotational velocity around a particular axis, is known as the angular momentum. This is a vector quantity (more specifically, a pseudovector). The formula for angular momentum is:
$L = m \times v \times r$
Here, $L$ is the angular momentum, $m$ is the mass of the object, $v$ is the velocity of the object and $r$ is the radius.

Note: The terms force and momentum are related to each other and their relation is given by Newton’s second law of motion. The rate at which a body's momentum varies over time is proportional to the force exerted and occurs in the same direction as the force, according to Newton's second law of motion.
