Concussions‚ Football‚ and Physics The NFL Playoffs‚ Steelers‚ Bengals. The running back Giovani Bernard receives the ball and looks up field‚ and finds himself staring at a linebacker Ryan Shazier. Shazier explodes onto him and knocks Bernard out cold. These jarring hits are common in the NFL‚ but most people don’t understand the consequences of them. Later on in life‚ football players that received head trauma experienced side effects later on‚ like CTE. CTE‚ or chronic traumatic encephalopathy

Required Vocabulary – IB 12 Higher Level Physics and Physical Measurement 1. Fundamental Units – seven basic units of the SI measurement system: kilogram‚ second‚ mole‚ meter‚ ampere‚ Kelvin‚ candela. 2. Derived Units – units that are combinations of fundamental units. These combinations may or may not have a separate name. (eg. 1 kg m/s2 = 1 N) 3. Accuracy - An indication of how close a measurement is to the accepted value (a measure of correctness). 4. Precision - An indication

As the height of the roller coaster increases‚ the speed of the marble decreases; and vice versa. When the height of the roller coaster is at it’s peak‚ the highest point‚ and the motion of the marble is going uphill; the speed has less kinetic energy than it has potential. The potential energy is being stored up‚ as the marble’s velocity is at an upward motion. Once the ball reaches the highest point and starts moving in a downwards motion‚ it releases the stored energy and gains kinetic energy

The Hurdle Before a diver jumps off of a springboard‚ he does a sort of hop-skip step called a hurdle. After doing a few steps‚ the diver leaps up into the air with his arms raised. When he lands back down on the tip of the board‚ he swings his arms down past his legs and then up‚ leaping into the air and off of the board. The purpose of this hurdle is as follows: A diver cannot simply stand on the end of board‚ step off‚ and expect to have the power to go up or the momentum to rotate his

Physics C-110 Module 1 Chapter 1 1. What is science? Science is a body of knowledge that is ever changing. It is made up of not only facts but also theories that are made up of well-tested hypotheses. 2. Distinguish among the scientific fact‚ hypothesis‚ law and theory As stated above‚ a theory is made up of well-tested hypotheses‚ which in themselves are well educated guesses yet to be proven. A fact is something that can change over time even though it was agreed upon by knowledgeable
