Because there is no non-conservative force, the kinetic energy and total linear momentum of the billiard balls are preserved.
In an elastic collision of two billiard balls, which of the following quantities remain conserved during the short time of collision of the balls a) kinetic energy b) total linear momentum Give a reason for your answer in each case.
