+kRrIzZmAl Xtha The term inelastic collision is used in some books but not all to refer to any situation in which the collision is not perfectly elastic and kinetic energy is lost in the process. Perfectly Inelastic Collisions mean that the two objects stick together after the collision and do not bounce off of each other at all. This situation also tends to lose the most kinetic energy of any type of collision.
+Jennifer Cash when mud is thrown in the wall... it perfectly inelastic...coz it sticks with d wall..and during this,do they possess final velocity?? i think the final velocity is zero coz wall was in the state of rest initially and mud cannot displace it... so the final velocity must be zero is it???
+kRrIzZmAl Xtha while throwing mud at an object is perfectly inelastic, the wall is not an isolated object (it is fixed to the floor). So we can not use the equations in this video for non-isolated collisions. You could use the equations for a situation where you throw a mud ball at a target on a slippery surface. Then when the mud hits, it will transfer some momentum, the target and mud will move, and the equation in this video will apply.
and what is the diff. between inelastic collision and perfectly inelastic collision???
