  1. Force and Motion

  2. Fermilab

  3. Fermilab

  4. Physics explains lots of Everyday Stuff too

  5. Isaac Newton’s Laws of Force and Motion o “Objects at rest want to stay at rest. Objects in motion want to stay in motion.” “To change an object’s motion, you must apply a force.” “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.

  7. Galileo’s Law of Falling Objects o “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

  8. Rotational Motion

  9. Rotational Motion The distribution of mass is what matters!

  10. Conservation of Momentum

  11. Conservation of Angular Momentum how-to-draw-cartoons-online.com Right-Hand Rule

  12. 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

  13. Fermilab Come visit us anytime!!

  14. Extras

  15. Physics explains things at the very Largest Scales

  16. Physics explains things at the very Smallest Scales

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

  18. Conservation of Energy Is a bit trickier to see because ENERGYcan take so many different forms…

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