1. The problem statement, all variables and given/known data Is following statement True or False? For inelastic collusions, the total KE of colliding objects just after collision is less than the total KE just before collision. The answer is given as False with a mention saying: "This is normally true but in some cases it could increase(why?)". 2. Relevant equations Total KE initial = Total KE final The above is true only for elastic collisions. 3. The attempt at a solution For inelastic collisions, some of the KE is always lost and therefore total KE of colliding objects must decrease. The only way that total KE could increase is when some of the mass of colliding objects gets converted to KE, but not sure if this really happens.
