1. Things in the
Universe are
always moving!
But what gets the ball rolling so to
speak?
2. It took the likes of a very intelligent
person to figure out the solution to
this problem.
• This happened hundreds of years ago in
England.
• During the time span of 1642-1727 an English
physicist and mathematician named “Sir Isaac
Newton” made some of the most incredible
discoveries of the day.
• This time span is also called the “Renaissance,”
or “Re-Birth.”
– This is because the entire European continent was
coming out of a time period called the “DARK AGES.”
4. What were the DARK AGES?
• The so-called dark ages were a period of time
where most aspects of life in Europe were
pretty bad.
– There were very little cultural, social, economic,
art, and medical advances made
• The time era was portrayed as being very sullen
or depressing.
– The people were all said to be in a “very bad
mood”.
• A lot of this can be attributed to a “Pandemic”
that occurred during this time called the
“BLACK DEATH.”
– The Black Death is now commonly known as
the “Bubonic Plague.”
• It is still around today but you don’t hear about it
much because of the advances of medical
science.
– The Black Death was an incurable disease that
was very contagious.
• It is caused by a Bacteria carried by fleas.
• The fleas bit an infected rat and then carried the
disease to a person where they too were bitten
and contracted the illness.
5. You see people didn’t make the
connection between the rats, fleas,
and people.
• They continued to live in squalor.
– The filth that surrounded them provided
a great place for the rats to thrive, and
the fleas as well.
• As long as this trash was there, so was
the disease!
• Bubonic Plague kills by destroying
your lymphatic system.
– Which is important because it filters the
“nasties” out of your blood.
• It forms a “Pus-Filled” blister that is
filled with the bacteria that causes
the disease.
– It erupts and spreads the bacteria, and
thus the disease.
6. There is a Children’s Nursery
Rhyme that was written during this
time.
• Ring around the Rosey.
– This was one of the symptoms of the plague.
• A white ring around an inflamed red swelling that looked almost like
a pimple.
• Pockets full of Poseys.
– People carried flowers with them to hold under their noses to
overcome the powerful stench that was found around all of the
dead bodies.
• That and the fact that they thought that the disease was transmitted
by the smell.
• Ashes, Ashes.
– There were so many bodies to bury that they couldn’t keep up so
they burned them.
• We all fall down!
– Almost everyone that contracted the disease died!
7. Here are some more odd facts
about the “Plague.”
• Death from the plague was horrible, but swift. Victims
often “ate lunch with their friends, and ate dinner with
their ancestors in paradise.”
• The first signs were generally aching limbs, and vomiting
of blood. Then the lymph nodes would begin to swell.
The lymph nodes are glands found in the neck, armpits,
and groin. The swelling continued for three or four days
until the lymph nodes burst. The swiftness of the
disease, the enormous pain, the grotesque appearance
of the victims, all served to make the plague especially
horrifying.
• Some Europeans believed the plague was a sign from
God. Groups known as flagellants tried to atone for the
sins of the world by inflicting punishments upon
themselves.
8. And who could forget Monty
Python’s famous “Bring Out Your
Dead Sketch.”
9. But enough about that!
• Back to Sir Isaac Newton!
– Sir Isaac Newton discovered one of the most
important relationships in physics:
• The link between the force on an object, its mass, and its
acceleration.
– Before the age of 30 he formulated the basics laws of
mechanics, discovered the universal law of
gravitation, and invented calculus.
– His discoveries helped to explain many unanswered
questions.
• How do the planets move?
• What causes tides?
• Why doesn’t the moon fall to the Earth like other objects do?
10. Sir Isaac Newton’s three (3) Laws
of Physics
The First Law of Motion
• An object at rest will remain at rest unless acted
on by an unbalanced force. An object in motion
will continue with constant speed and direction,
unless acted on by an unbalanced force.
• Or in other words……..
– Unless you apply some force, things tend to keep on
doing what they were doing in the first place.
11. These are some examples of
Newton’s First Law of Motion.
• Objects in motion tend to
stay in motion, while
objects at rest tend to
stay at rest.
12. The Second Law of Motion
• The acceleration of an object is directly
proportional to the force acting on it and
inversely proportional to its mass.
• Or in other words……..
– Force causes an object to accelerate while
the object’s mass resists acceleration.
13. These are some examples of
Newton’s Second Law of Motion.
• A force is needed in order
to get an object to
accelerate
• The bigger the mass the
bigger the force needed
• 2nd Law Animation
14. The Third Law of Motion
• Whenever one object exerts a force on
another, the second object exerts an
equal and opposite force on the first.
• Or in other words……
– For every action, there is an equal and
opposite reaction. If you push on the wall, you
feel the wall pushing back on your hand.
15. These are some examples of
Newton’s Third Law of Motion.
• For every action there
is an equal, but
opposite reaction.
