" Internal forces can changes "

A : Internal forces can change the kinetic energy but not the momentum of the system. R : The net internal force on a system is always zero.

A : Internal forces can change the kinetic energy but not the momentum of the system. R : The net internal force on a system is always zero.

Choose the correct statement regarding a system of particles. Internal forces can change the kinetic energy of the system without changing system's momentum O Impulse can be defined as a very large force that acts for a very short time and causes finite change in momentum. Internal forces can change the potential energy of the system without changing system's momentum Internal forces can change the mechanical energy of the system without changing system's momentum.

Statement-1 : Internal forces can change total linear momentum of system. Statement-2 : Due to work of internal forces kinectic energy of system may change.
