The unit of change in momentum is :

To determine the unit of change in momentum, we need to understand the concept of momentum first. Momentum is defined as the product of an object's mass and its velocity. It is a vector quantity, meaning it has both magnitude and direction.

The unit of mass is typically measured in kilograms (kg), and the unit of velocity is measured in meters per second (m/s). Therefore, the unit of momentum is kg*m/s.

Now, to find the unit of change in momentum, we need to consider the definition of change in momentum. Change in momentum is equal to the final momentum minus the initial momentum. Since momentum is a vector quantity, the change in momentum will also be a vector quantity.

Therefore, the unit of change in momentum is also kg*m/s.
