Center of mass is a point of a body or group of bodies that represents the motion of a body when a external force is applied on the body or system. In this complete video lesson series we have discussed the need for the concept of center of mass. We have derived mathematical equation for the center of mass of a system using the concept that the algebraic sum of moments about center of mass is zero.

We have also derived equations for velocity and acceleration of the center of mass and proved that there is no effect of internal force on the motion of center of mass.

We have further discussed how center of mass is impacted when a body is added or when a mass is removed from a given system.

Here are the list of posts under the concept of center of mass.
