Sir Isaac Newton

• 1643-1727
• Born to a wealthy farmer, also named Isaac
  Newton.
• Attended free grammar school in Grantham
• Attended College at Trinity College Cambridge

3
Continued

• At Cambridge Newton studied Philosophy
• After buying an astrology book he became
  interested in Mathematics
• He published his own mathematics book in 1704
  called Opticks

• After being elected to the Royal Society in
  London in 1671 he became President in 1703
• Was never married
• After passing he was buried at Westminster Abbey

4
Opticks (1704)

• Composed of comprehensive work on light and
  color.
• It was divided into three different books that
  consisted of definitions, axioms, propositions,
  and theorems to proof by experiment
• It was the model for experimental physics in the
  18th century.

5
Newtons Light Theory

• According to Newton Light is composed of tiny
  particles corpuscles, emitted by luminous
  bodies."
• This theory was then replaced by the wave length
  theory in the 19th century

6
Light Theory

• Einstein and Mickelson rediscovered the light
  theory in a whole new way
• They say that light comes from electromagnetic
  radiation
• Electromagnetic radiation, which "travel as tiny
  bundles of energy, called light quanta, or
  photons, that behave as particles."

7
Newtons 1st Law

• I. Every object in a state of uniform motion
  tends to remain in that state of motion unless an
  external force is applied to it.
• Newtons 1st law came from Galileo and his theory
  on inertia
• Also known as the Law of inertia
• Inertia tendency of an object to resist changes
  in its velocity.

8
.First law

• Gravity pulls everything toward the center of the
  earth
• An object at rest tends to stay at rest till a
  action or force is acted upon it

9
.First Law

• A force is a push or pull upon an object
  resulting from the object's interaction with
  another object.
• There are nine different types of forces
  including Frictional, Tensional, Applied, and
  Gravitational.

10
Newtons 2nd Law

• II. The relationship between an object's mass m,
  its acceleration a, and the applied force F is F
  ma. Acceleration and force are vectors in this
  law the direction of the force vector is the same
  as the direction of the acceleration vector.
• The Most difficult but most important law of the
  three

11
..More.

• All objects move at 32 ft/sec
• ForceMass x Acceleration
• The force of an object is equal to its mass times
  its acceleration

12
.2nd Law

• Rain drops reach terminal velocity before
  reaching the earth
• When falling everything falls at the same rate
  but the one thing that is different is the force
  that it hits the ground

13
Newtons 3rd Law

• III. For every action there is an equal and
  opposite reaction.
• This law is the easiest to understand
• Forces come in pairs
• Things like shooting a shotgun, the gun shot
  force is mostly in the shoulder

14
.Examples of the 3rd Law

• A bird flying through the air, the wings push the
  air down and the bird goes upward.
• Car hitting a tree/pole the car stops and if you
  arent wearing your seat belt you will keep up
  with the motion of the car.
• A rocket taking off, the force is pushing down
  while the rocket is moving up

Review..

• Sir Isaac Newton
• Invented the term Opticks
• Work on light and color
• 3 different books definitions, axioms,
  propositions
• Light theory
• Light is composed of tiny particles corpuscles,
  emitted by luminous bodies
• Electromagnetic radiation

16
Review..

• Three major laws
• First Law
• A force is a push or pull upon an object
  resulting from the object's interaction with
  another object.
• Inertia tendency of an object to resist changes
  in its velocity
• Second Law
• The relationship between an object's mass m, its
  acceleration a, and the applied force F is F ma.

17
.Review

• All objects move at 32 ft/sec
• Third Law
• For every action there is an equal and opposite
  reaction
• Forces come in pairs

Quotes

• "Errors are not in the art but in the
  artificers.
• "O Diamond! Diamond! Thou little knowest the
  mischief done!
• "If I have seen further (than you and Descartes)
  it is by standing upon the shoulders of Giants."
