Hello aspirant,

Hope you are doing well,

Momentum, product of the mass of a particle and its velocity. Momentum is a vector quantity; i.e., it has both magnitude and direction. Isaac Newton's second law of motion states that the time rate of change of momentum is equal to the force acting on the particle.

The Momentum Calculator uses the formula p=mv, or momentum (p) is equal to mass (m) times velocity (v).

There are two types of momentum

Linear

Linear momentum (momentum for brevity) is defined as the product of a system's mass multiplied by its velocity. In symbols, linear momentum p is defined to be p = mv, where m is the mass of the system and v is its velocity. The SI unit for momentum is kg · m/s.

Angular

In physics, angular momentum (rarely, moment of momentum or rotational momentum) is the rotational equivalent of linear momentum. It is an important quantity in physics because it is a conserved quantity—the total angular momentum of a closed system remains constant.

Hope this information helps,

Best of luck

Dear student,

Momentum is the product of the mass of a particle and its velocity. Momentum is a vector quantity, that is it has both direction and magnitude and follows vector laws of addition.
Also according to Newton's second law of motion - the time rate of change ofmomentumis equal to the force acting on the particle.

Dimension of momentum is - [M][L][T^-1]
And it's SI unit is kgm/s

Hello Candidate,

Momentum is defined as the product of mass and velocity of an object. It is a vector quantity and it is denoted by p. It has formula i.e. p = mv. And the SI Units of momentum is Kg.m/s.  Furthermore, momentum is of two types. The one is linear momentum and the another one is angular momentum.
