In this Science (Physics) video in Hindi for Class 9 we explained and defined momentum (linear momentum). It is a topic from chapter 9 - ' Force and Laws of Motion' from NCERT.
Momentum a body is the product of the mass of that body and its velocity. As velocity is a vector quantity, momentum is also a vector quantity. Momentum of a body has direction same as that of its velocity. The S.I. unit of momentum is kg m/s (kilogram metre per second).
Momentum has several applications in Physics. Most notably, it is used in the law of conservation of linear momentum. It means when a collision among several bodies occur, the total momentum of those bodies before and after collision remains the same. We are going to use the concept of momentum in the topic of Newton's second law of motion.
