Momentum is the product of an object's mass and its velocity. It is a vector quantity. Newton's second law can be rearranged to reveal that the net force on an object is equal to the rate of change of the object's momentum. The larger the net force experienced by an object, the more rapidly the object's momentum will change.

Wow that's amazing for me 😮. Cause I'm from Pakistan Peshawar city. I study at Khan academy here we have, I go there every afternoon. But the good news for me is that - that we studied today momentum. 😊
I grasp the implication of momentum however I do not understand what momentum itself is.

It is a mathematical quantity which has physical significance like how i understood it is it helps us to understand some physical phenomena but isn't a physical quantity itself. It is mathematical in nature and people get confused because they think momentum is a fundamental property of an object but it is not. I am saying this again it is a mathematical quantity

Earlier, I also tried to interpret the momentum. I mean what exactly it is... I understand that if a ball has more momentum then it hurts more but again I can't relate it physically. I need you think it like a mathematical equation relating mass and velocity. That 'more momentum more hurt' part, it has do with the energy possessed by a moving mass. Kinetic energy is also directly related with mass and velocity squared. It is my way of thinking about momentum. Hope that helps.
Nice one.
Nice
Who is the teacher here? I recognize him from another channel he has but I forgot.
