Sir Isaac Newton
  • Ouch! Darn that apple!
  • By Wendy Ma

2
Intro
  • Born January 4th, 1643
  • Lincolnshire
  • Cambridge University
  • Professor, alchemist
  • the universe worked like a well-oiled machine
    that has a few simple laws governing it
  • Died March 31st, 1727

3
Reflecting Telescope
  • mirrors
  • Magnified 40 times

4
Optics
  • prism
  • quantitative patterns
  • angles of refraction
  • thickness of thin films
  • corpuscles
  • Opticks

5
Mathematics
  • Mathematics professor at Trinity College,
    Cambridge
  • Calculus
  • Differentiation
  • Integration
  • method of fluxions and inverse method of
    fluxions

6
1st Law of Motion
  • Objects at rest will stay at rest and objects in
    motion will stay in motion in a straight line
    unless acted upon by an unbalanced force
  • Inertia

7
2nd Law of Motion
  • F m a
  • An object accelerates in the direction the force
    is moving it
  • Ex. Cannon is fired, ball propelled
  • F (cannon) m (cannon) a (cannon)
  • F (ball) m (ball) a (ball)
  • m (cannon) a (cannon) m (ball) a (ball)

8
3rd Law of Motion
  • For every action, there is always an opposite and
    equal reaction
  • Ex. Fish fins

9
Gravity
  • Gravity force that causes things to fall down
  • two bodies will experience a mutual attractive
    force that is proportional to the product of
    their masses Encyclopedia of Earth and
    Physical Sciences

10
Other Achievements
  • Written in Principia
  • sound
  • comets
  • tides and equinoxes
  • fluids

11
Activity
  • Which of the laws of motion do you think are more
    important in our everyday lives? Explain.
  • Reminder
  • An object will stay in motion unless acted upon
    by an external force
  • For each action, there will always be an equal
    and opposite reaction
