Question

What is the difference bw the magnitude of change in momentum and the change in magnitude of momentum

Answer 1

Answer:

Explanation:

The impulse acting on an object produces a change in momentum of the object that is equal in both magnitude and direction to the impulse. When a ball bounces back with the same speed, the momentum changes from mv to -mv, so the change in momentum is 2mv.

Change in Magnitude of velocity - This line basically means that the speed is changing. It means that if a car is moving with 20kmph at a certain instant and then at the next instant it's speed is 40kmph, the magnitude of the car's velocity or speed has changed. ... The magnitude of change in velocity is not zero now.
