Impulse, Collision, and centre of Mass

As the title suggests, this topic can be broadly divided into three sections. In this topic we have defined impulse of a force, the impulse-momentum theorem, the principle of conservation of linear momentum etc. You have already been introduced to the concept of momentum in the topic 4 (Newton’s Laws of Motion). But it needs more than that brief introduction to have a stronger grasp on the topic. The most useful application of the momentum principle is the study of collision between two bodies. The definition of the centre of mass of a system of particle will show the motion of a system of particles is equivalent to the motion of one representative particle located at the centre of mass. You will develop a clear concept of the topic through the video lectures on Impulse and Impulse-Momentum Theorem, Motion of a Body of Variable Mass, Principle of Conservation of Linear Momentum, Collision in One Dimension, Collision in Two Dimensions, Finding Centres of Mass of Uniform Rigid Bodies, Motion of a System of Particles etc.
