   The third law of motion… When there is an action there is a reaction and also friction.

   The modern tennis ball is comprised of two major parts, the inner core and the outer cloth covering. The inner core is constructed of two half-shell pieces of formed rubber, which are joined together with adhesive to form a single core. Two dumbbell shaped pieces of cloth are attached to the ball core by adhesive to give the tennis ball its classic appearance. The thickness and density of the ball cloth is matched to the court type for which the ball is designed.
   The balls currently in use can be subdivided into two categories:
   Pressurized balls have a core pressurised with air or nitrogen. These balls lose their pressure, and hence playing properties, over time.
   Non-pressurised balls are made from a thicker rubber core, and the pressure within the core is equal to the ambient pressure. These balls tend to hold their playing characteristics for a longer period of time, as it is only the cloth that deteriorates. Most players feel no difference between presurized and presureless balls, but top-level players claim a notable difference and thus prefer the former.

   The 3rd law of motion.
   every action has an equal and opposite reaction.
   the force going into the ground “bounces” it back up.
