What is the SI unit of momentum?

Kg m/sec

The correct answer is option 2. Kg m/sec.

Momentum is a physical quantity that describes the motion of an object. It is defined as the product of an object's mass and its velocity. The SI unit of mass is kilograms (kg), and the SI unit of velocity is meters per second (m/s). Therefore, when we multiply the unit of mass (kg) by the unit of velocity (m/s), we get the SI unit of momentum, which is kilogram meter per second (kg m/s). This unit represents the amount of motion an object possesses and is commonly used in physics to describe the momentum of particles, objects, or systems.
