Describe the significance of the concept of centre of mass.
Asked by Topperlearning User | 4th Aug, 2014, 02:25: PM
Centre of mass of a system is a point where the total mass of the system is supposed to be concentrated and all the external forces act there. So, the description of motion becomes easier in terms of centre of mass of the system. Thus centre of mass enables us
- To apply Newton's law of motion to extended bodies without difficulty
- To apply law of conservation of momentum/energy to a single particle rather than individual particles.
