Question

What is momentum? what is it's si unit?​

Answer 1

In SI units, momentum is measured in kilogram meters per second (kg⋅m/s). Newton's second law of motion states that the rate of change of a body's momentum is equal to the net force acting on it.

Answer 2

$\sf\huge\underline\bold \orange{ Momentum }$

In Newtonian mechanics, linear momentum, translational momentum, or simply momentum is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction. If m is an object's mass and v is its velocity, then the object's momentum is: \mathbf{p} = m \mathbf{v}.
