What is the unit for momentum?

Momentum is defined to be ‘mass x velocity’, so it is a vector, in the same direction as the velocity. Mass is measured in kilograms, kg, and velocity is measured in metres per second, m/s. These are the standard SI units of these quantities, which most countries now use. Momentum is then in kg m/s. read more

The units of momentum are the product of the units of mass and velocity. In SI units, if the mass is in kilograms and the velocity in meters per second then the momentum is in kilogram meters/second (kg m/s). read more

Momentum is measured in standard units of kilograms times meters per second (kg m/s). The Conservation of Momentum Principle The principle of conservation of momentum states that in an isolated system, two objects that collide have the same combined momentum before and after the collision. read more
