Sir Isaac Newton
His life and accomplishments
By Kelsey Zolac
Facts Isaac Newton was born on January 4, 1643
Born in Woolsthrope, Lincolnshire, England, UK
Died on March 31, 1727, in London, England
Was a Philosopher, Mathematician,
Astronomer, Physicist, and Scientist
Was abandoned by mother and left with
maternal grandmother until age 12
More Facts Went to the University of Cambridge,
Trinity College, and The King’s School
His love for science did not go unnoticed
Graduated with no honors or distinctions
Earned the title of scholar
In 1667 he was elected a minor fellow at
Trinity College
Accomplishments
Invented the reflecting telescope in
1668
In 1687 this magnum opus –
Philosophiæ Naturalis Principia
Mathematica was published
Sir Newton also discovered gravity.
Laws of Motion
The Laws of Motion are defined as
“The three laws that govern the
motion of material objects”
In Philosophiæ Naturalis Principia
Mathematica Sir Isaac Newton
formulated his Three Laws of Motion.
First Law of Motion
“An object in motion stays in
motion (same speed and
direction) unless acted upon
by an unbalanced force. An
object at rest stays at rest
unless acted upon by an
unbalanced force.”
Example of Law 1
An example of this law is a
car driving at a constant
speed in one direction
then hitting a brick wall.
In this case the car was an
object in motion until it hit
the brick wall, the
unbalanced force.
Second Law of Motion
The second Law of Motion says,
“Acceleration is produced when a
force acts on a mass. The greater
the mass (of the object being
accelerated) the greater the
amount of force needed (to
accelerate the object).”
F=MA
Example of Law 2
An example of Law 2 is
when someone is trying
to push a car, but can
not due to the fact the
car has a greater mass
than the person, and
the person isn’t pushing
hard enough.
Third Law of Motion
“For every action there is
an equal and opposite re-
action,” is the third law
of motion.
Example of Third Law
An example of the
third Law of Motion is a
balloon releasing air.
The air is let out in the
opposite direction the
balloon itself is going.
Gravity Sir Newton discovered gravity
when he saw an apple fall from a
tree.
Realized some force must be
acting upon the apple to make it
fall
Newton used the idea of gravity to
explain the astronomical
observations of Kepler
Conclusion Sir Isaac Newton discovered
some of the biggest things in
science such as gravity and the
Laws of Motion.
His findings will be taught to
many generations to come
