Momentum and Its Components

The video tutorial introduces the concept of momentum, defining it as the product of mass and velocity. It explains that momentum is a vector quantity, represented by the symbol 'P' and measured in kilogram meters per second. The tutorial covers momentum in both one-dimensional and two-dimensional motion, highlighting the importance of vector components in two-dimensional scenarios. The video emphasizes the relationship between velocity and momentum, showing how the direction and magnitude of momentum are influenced by mass and velocity.

What is momentum defined as in physics?
