The force depends on the field the tennis ball is in. All objects with mass attract all others; a tennis ball and the earth attract each other equally with a force equal to what we call the "weight" of the ball in pounds or ounces. Pounds and ounces are technically measures of force, NOT mass. They attract each other as described by the formula: where "m" is the true mass (usually in grams), "r" is the distance between the objects (in meters) and "G" is a constant: Ouch!
Top spin is when you brush up on the ball with the racquet to make top spin. Top spin is used in tennis to make the ball drop onto the court so it will not go out of play. It is the most common used shot in tennis. It is very consistant.
