Question

define Momentum. It is a scalar and vector quantity ? give its unit and dimension​

Answer 1

Answer:

$\huge\bold\red{Momentum}$

Momentum of a body is defined as the product of its mass and velocity.

If a body is at rest ,its velocity is zero and hence its momentum is zero.

Momentum is a vector quantity.

SI unit of momentum is kilogram metre per second (kg*m/s)

dimension of p = [m^1,L^1,T^1]

p = m×v

where, p is momentum

m is mass of the body

v is velocity of the body

Answer 2

Answer:

Momentum of a body can be defined as the product of mass of the body and velocity of the body. It means momentum of a body is directly proportional to the mass of the body. Momentum of a body is also directly proportional to the Velocity of the body. The SI unit of momentum is kilogram metre per second.

It is a vector quantity.
