Why kinetic energy is not conserved in an inelastic collision?

Open in App

Solution

$Answer The kinetic energy is not conserved in an inelastic collision because the kinetic energy lost in the collision appears in the form of heat energy, sound energy or light energy . the force of interaction in an inelastic collision are non conservative in nature .$

Answer carefully, with reasons :

(a) In an elastic collision of two billiard balls, is the total kinetic energy conserved during the short time of collision of the balls (i.e. when they are in contact) ?

(b) Is the total linear momentum conserved during the short time of an elastic collision of two balls ?

(d) If the potential energy of two billiard balls depends only on the separation distance between their centres, is the collision elastic or inelastic? (Note, we are talking here of potential energy corresponding to the force during collision, not gravitational potential energy).
