Physics Behind Tennis

Tennis, a difficult sport to master, has many forces and transfers of energy acting upon it.  As a two tennis players rally a ball between themselves, it seems unreal as the ball flies to incredible speed between them.  This can be explained through Newton's law as the ball exerts a force to the racket, the racket exerts the same magnitude force but the opposite direction.  Also the ball hitting the racket or the ground experiences a inelastic collision.  This is why, it is hard for tennis playe

Swimming

Swimming is a popular sport that involves a ton of physics. The physics of swimming involves an many forces between the water and the swimmer. It is these forces which propel a swimmer through the water. In order to swim, a swimmer must "push" against the water using a variety of techniques. There are four major techniques used for swimming. They are, Front Crawl (freestyle), Breaststroke, Backstroke, and Butterfly stroke.  There are others, but ate used for recreational uses.  By moving his or

The Physics of a Football in the Air

Since I was watching football (Go Bills!), I was thinking about the forces acting upon a football in the air.  Newton's laws help dictate the pattern of all moving objects, including footballs.  The path of a football's flight is not random, it is the result of the physical forces of inertia, air resistance, and gravity.  Newtons first law of motion states that an object in motion will stay in motion unless acted upon by an outside force.  A football travels in a parabolic path because of outsid

Shooting Your Grade Lab

On Friday, September 16, 2016, at 10:25 to 11:07,  Dan Fullerton presented a lab.  Unfortunately,the best 22 students of the high school, failed!  Thankfully, Mr, Fullerton allowed us to redeem ourselves by writing what the right answer was and why we failed.  This lab, Mr. Fullerton assigned to us was to shoot a projectile and predict where it would land.  By doing this we had to use kinematics.  We failed this lab for many reason. One main one was our lack of communication among our class. We

Curving a Soccer Ball

Curving a soccer ball, seems easy enough.  Everyone is able to do it, on purpose or accidentally.  All you have to do is kick a soccer ball.  And yet, there is so much physics in how a person can curve a soccer ball.  The reason a soccer ball curves is because the kicker kicks the ball at a certain angle and velocity causing the ball to spin.  However, once the ball is in the air, it is really the air that is curving the ball.  This seems impossible, but the air resistant will curve and bend the
