Respected tutors! I asked a question some time ago.My goal of asking question ,even after myself being a tutor, is to get clear with not so intuitive concepts, which i find intriguing. Q.What is the change in kinetic energy(ies) of body(ies) after collision of 2 moving bodies; you can take inelastic or elastic collision. 1- Remains same 2-Decreases 3-increases 4-any other possibilty All answers with 'decrease' options are correct, either elastic or inelastic collision. you can take any example and check. Q.Just think can KE be zero after collision? - this time its a bit more intuitive. Thanks.

it should remains same.. but if friction is taken into consideration then decreases would be the right option.
