Lecture 11: sport biomechanics example and linear kinetics i. Tommy john: played for 26 years (1963-1989, w/l: 288-231 (#7 for left handers), 3. 34 era, four time all star, playing in here world series, surgery performed in 1974, before: 12 years, 120 wins, after: 14 years, 164 wins. Reminder: what is mechanics: classical (newton, statics, dynamics, kinematics (motion, kinetics (forces) Outline: force: definition and different types, an action that changes the acceleration of something, can be applied to an object, from zero velocity to non-zero velocity. Internal vs. outside the body: internal: muscle forces, outside: force between feet and ground, resultant forces, force, pressure, stress, pressure: balloon, stress: force exerted on area, newton"s laws of motion. Newton"s laws: relate forces to motion (kinetics to kinematics, govern how the body interacts with nature, published in 1687, foundation of physics, mathematically impossible, so had to invent calculus.
