Physics Of The Field Of Medicine - 1381 Words

The study of physics over the last year has been intriguing and extremely valuable to my education to pursuer a career in the field of medicine. Learning physics in the classroom is one thing, but being able to apply it to everyday scenarios is what has made this course so interesting compared to other various science courses offered at Gonzaga. When I was three years old my parents bought me my first pair of hockey skates and since then hockey has consumed my entire life. Upon receiving this assignment I was enthusiastic about applying knowledge form the classroom into my hockey life. The above picture was taken my sophomore year at Gonzaga at Eagles Ice Arena in Spokane, Washington.

Force and acceleration are both vectors and will p oint in the same direction. Newton’s third law states that forces occur in pairs, so when a force acts on an object there will be a reaction from the object to where the force is applied. The second object will exert a force back onto the original object that is equal in magnitude but opposite in the direction. Newton’s laws are able to yield the equation F=ma. In the case of figuring out the hockey shot a=(Vf2-Vi2)/2Δx, and when you combine the equation together you get F=m=(Vf2-Vi2)/2Δx. All that is needed to figure out the force on the hockey puck is the initial velocity, the final velocity, the mass and the distance traveled. The mass of a hockey puck is .160kg and the length traveled is 17.3 meters. The initial velocity of the puck in my case was 0 m/s and the final speed of the puck was 87 mph measured by a radar gun which converted to 38.89 m/s. With all this information the force could be calculated. F=.160kg(38.89 m/s 2 – 0 m/s 2)/2(17.3m) which equaled 6.99 N or 7.00 N. The second thing I wanted to look in this picture was the transfer of kinetic energy from the stick to the puck and to see if kinetic energy would be conserved in this collision. A collision is classified as is momentum being conserved from one moving object striking another
