Volleyball and Physics



Physics applies to volleyball in many ways. When you hit or serve a ball there is a force being applied to the ball which would be your hand. The ball also exerts a force back onto your hand. Your hand and the ball would be an Action-Reaction pair because of newtons 3rd law: All forces come in pairs. If object one exerts a force on object two, then object two must exert a force back on object one, which is equal in magnitude and opposite in direction. Also when the ball is served or hit, it has initial and final vertical and horizontal velocities so it would be an angled projectile. The ball however does have air resistance when in the air. Its much easier to hit a volleyball than many other things such as bowling balls, basketballs, and soccer balls because volleyballs have less inertia. Also the gravitational force of the earth impacts every part of volleyball. One of the reasons I love playing volleyball is because of reaction time.. The reaction time of the back row on the other side of the net is generally too slow to pick up our team's hits and tips since the ball is accelerating at 9.81 m/s^2 and we applied a downward force and that is why we have done so well this season (And Callari ofcourse!). Friction also plays a role in volleyball because if you dive after a ball that your teammate shanks and you slide on the floor that alot of mews and alot of floor burns.. and if you think about it.. If two cats are on a roof which one would slide off first? The one with the smaller mew... :lolu:
