Why a metal ball rebounds better than a rubber ball?

A metal ball hits a wall and does not rebound whereas a rubber ball of the same mass on hitting the wall the same velocity rebounds back. It can be concluded that–

Why are metall hydroxides better alternative than sodium hydrogen carbonate in antacid ?

A small ball of mass m is aligned above a larger ball of mass M = 0.63 kg (with a slight separation, as with the baseball and basket ball of Fig. ), and the two are dropped simultaneously from a height of h = 1.8 m. (Assume the radius of each ball is negligible relative to h.) (a) If the larger ball rebounds elastically from small ball rebounds elastically from the larger ball, what value of m results in the larger ball stopping when it collides with the small ball ? (b)What height does the small ball then reach ?

A metal ball and a rubber ball , both having the same mass , strike a wall normally with the same velocity. The rubber ball rebounds and the metal ball does not rebound. It can be concluded that

Which of the following bodies have more inertia? (i) A metal ball and a rubber ball of the same size. (b) A car and a bus.

A lead ball and rubber ball having same mass, strike normally on a smooth vertical wall with the same velocity. The lead ball falls down after striking but the rubber ball bounces back. Then

Why are metal hydroxides better alternative than sodium hydrogen carbonate in antacids ?

On what factor does the inertia of a body depend ? Which has more inertia, a cricket ball or a rubber ball of the same size ?
