Sir Isaac Newton was an influential English scientist born in 1642 who made important discoveries in physics and mathematics. He developed the three laws of motion and the law of universal gravitation. Newton studied at Trinity College, Cambridge and was a professor there, making his key discoveries while the university was closed from 1664 to 1666. These included establishing that white light is made of all the colors of the rainbow and deducing that the force that causes apples and the moon to fall is the same force that governs the entire universe.

2. Sir Isaac Newton is regarded to be one of the most
influential scientists of all time. He studied physics
and created the three laws of motion. This
PowerPoint will tell you more about Sir Isaac
Newton:
He was………
Born: December 25, 1642, Woolsthorpe, United Kingdom
Died: March 20, 1727, Kensington, United Kingdom
Full name: Sir Isaac Newton
Education: Trinity College, Cambridge (1667–1668).
Parents: Isaac Newton Sr., Hannah Ayscough

3. Isaac Newton studied in Cambridge and he was a
professor there from 1669 to 1701. His most
important discoveries were made during 1664 to
1666 when the university closed and he retired
from his job and returned to his hometown.
From there he discovered the law of gravity from
the apple story. He also discovered that white
light is made of all the colours of the rainbow.
These things have made him able to make
contributions to mathematics, astronomy and
physics.

4. An object at rest will remain at rest unless acted on by an
unbalanced force. An object in motion continues in motion with the
same speed and in the same direction unless acted upon by an
unbalanced force. This law is often called "the law of inertia".
-Isaac Newton
It means:
This means that there is a natural tendency of objects to keep on
doing what they're doing. All objects resist changes in their state of
motion. In the absence of an unbalanced force, an object in motion
will maintain this state of motion. This law is the same reason why
you should always wear your seatbelt.

5. Acceleration is made 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).
-Isaac Newton
This means:
Everyone knows that heavier objects require more force to
move the same distance as lighter objects.
The Second Law gives the exact relationship between
force, mass, and acceleration. It can be also told as a sum
like this:
Force = Mass times acceleration

6. For every action there is an equal and opposite re-
action.
-Isaac Newton
This means that for every force there is a reaction
force that is equal in size, but opposite in direction.
That is to say that whenever an object pushes
another object it gets pushed back in the opposite
direction equally hard.

7. • Isaac was born in England, and was a
physicist, astronomer, mathematician, philosopher, alchemist and
theologian.
• In 1687, Newton published Philosophae Naturalis Principia
Mathematica, which is one of the most important books in the history
of science. In it Newton describes gravitation and the three laws of
motion.
• Newton’s law of gravitation describes the gravitational attraction with
bodies with mass..
• Newton moved to London in 1696 and took up a job as the Warden of
the Royal Mint.
• Newton is known to have said that his work on the theory of
gravitation was made by watching an apple fall from a tree. This story
is still popular today.
