State the incorrect statement among the following
When conservative force acts on a system and performs positive work on body, potential energy of body decreases
In an inelastic collision of two bodies linear momentum of system remains conserved
In case of inelastic collision, final kinetic energy is less than initial kinetic energy of the system
Total kinetic energy of system is conserved no matter what internal and external forces on body are present
Solution:
In the presence of non-conservative internal forces (like friction or impact forces in inelastic collisions), total kinetic energy is not conserved, making statement (4) incorrect.
