Question

Law of conservation of energy for system of particle

Answer 1

For a system of particles, the sum of the work done to all particles will be equal to the change in energy of all particles collectively, essentially combining multiple conservation of energy equations into one. ... Only external forces, such as the friction force need to be included as part of the work done to the system
