Momentum of cricket ball is higher than table-tennis ball |
During the game of table tennis if the ball hits a player, it does not hurt him. On the other hand, when a fast-moving cricket ball hits a spectator, it may hurt him. Cricket ball possess higher momentum than Table-tennis ball. These observations suggest that the impact produced by the objects depends on their mass and velocity. The momentum, p of an object is defined as the product of its mass, m and velocity, v. That is, p = mv |
