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.

Assertion : Internal forces acting on the system cannot change linear momentum of the system . Reason : Internal forces can change kinetic energy of the system.

Internal energy U of a system may change when

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.
