4. 4 Physics explains lots of Everyday Stuff too

5. o o Isaac Newton’s Laws of Force and Motion 5 1.“Objects at rest want to stay at rest. Objects in motion want to stay in motion.” 2.“To change an object’s motion, you must apply a force.” 3.“For every action there is an equal and opposite reaction.” Isaac Newton, physicist, mathematician and aspiring hair model

6. Gravity is a Force. It definitely causes motion. 6

7. o o Galileo’s Law of Falling Objects 7 “All objects falling because of gravity fall at exactly the same speed, regardless of how heavy or light the objects are.” Galileo Galilei, physicist and astronomer

10. 10 The distribution of mass is what matters!

12. Conservation of Momentum 12

13. Conservation of Angular Momentum 13 Right-Hand Rule

14. What did we learn today? Newton and Inertia Moving things stay moving Stationary things stay stationary Unless you apply a force Galileo and Gravity Mass doesn’t matter – angle matters Rotating objects are different Shape matters Some things don’t change and that’s very useful for understanding Momentum, angular momentum, and energy 14

20. Gravity – angle matters! doesn’t move moves slowly moves faster moves fastest G G G G 20

21. Conservation of Energy 21 Is a bit trickier to see because ENERGY can take so many different forms…

22. Conservation of Energy where does the energy come from to: – sail a sailboat? – grow a plant? – drive a car? – a falling ball? – cook toast? 22
