What is Physics? • The science that studies: • Matter • Forces • Energy • Movement
Isaac Newton’s Laws of Motion The First Law: • Objects at rest remain at rest • Objects in motion remain in motion UNTIL YOU APPLY A FORCE
Isaac Newton’s Laws of Motion The Second Law: Force = Mass x Acceleration (F=ma) What forces are important in sports?
The Home Run Swing • Ball arrives on 100 downward trajectory • Alfonzo Soriano and Paul Konerko swing up at 250 • Ball takes off at 350 • If all conditions are right - home run! Adapted from A. Nathan, University of Illinois. http://www.npl.uiuc.edu/~a-nathan/pob/
Isaac Newton’s Laws of Motion The Third Law: For every action there is an equal and opposite reaction.
Conservation of Momentum If m1 = m2, then v1 = v2
Equipment features • Ball material, size, shape, and texture • Properties of the club, bat, racquet, or stick

Reaction Time in Baseball Courtesy of R. Adair through A. Nathan.
Compare your reaction time… Equation used: t = √((2d)/g)
Physical laws explain the world • Newton’s Laws of Motion • Conservation of Momentum These laws help us explain everything about sports. Physics really is everywhere!
