The Life of Isaac Newton
Isaac Newton was born on December
25, 1642 in England. The exact date of
his birth is disputed among many, but
December 25th is the date most
commonly given. As a child, Newton
preferred singing and playing the harp
over science. Even as an adult, he
never intended for his works to be
published. Isaac Newton is most famous
for his Three Laws of Motion, which
dictate how forces can influence an
object. These laws can be considered
the base of modern science due to their
unbreakable standards. Besides working in
the field of science, Newton wrote many
religious criticisms that urged readers to
not interpret the Bible literally. Isaac
Newton died on March 31, 1727. His
autopsy presented that he died of
mercury poisoning, which accounts for his
peculiar behavior in his later years.
Newton's figuring in the field of science,
especially motion, helped the world to
advance.
Newton’s First Law of Motion
Newton's first law of motion,
also called the law of inertia,
declares that every object in a
state of uniform motion tends to
remain in that state of motion
unless an external force is
applied to it. This means that
an object will not move unless
an outside force is added to it.
It also states that an object will
stay in motion as long as the
force is applied to it. The
object’s basic goal is to move
in the same direction and at the
same speed, and it will attempt
to right itself after its motion
has been tampered with. The
law of inertia can be
summarized as an object’s
motion resisting change. The
first law of motion helps to
explain why and how objects
Newton’s Second Law of Motion
Isaac Newton’s second law states
that the relationship between an object's
mass, its acceleration, and the applied
force 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. This
explains that when an object is put into
motion, its force and acceleration both
push the object in the same direction.
Also, the force that is applied to the
object can be calculated by multiplying its
mass and acceleration. This notes that
an object’s acceleration, also called
velocity, can change over time, an idea
that had never been explored before
Newton created this law. Finally, it
explains how when force it applied to an
object, its velocity changes. This law of
motion shows how force, acceleration,
and mass all contribute to how an object
moves.
Mass = 250g
Acceleration = 30
mph
Force = 7500 N
Newton’s Third Law of Motion
Newton’s third and final law of
motion explains that for every
action there is an equal and
opposite reaction. This law helps
to clarify how forces affect
motion. When a force, or action,
is applied to an object, the
object behaves oppositely and
equally. For example, if a ball
was rolled in one direction, it
would roll with equal force and
away from the place that it was
rolled. This law is important
because without it, an object’s
behavior would be sporadic and
unpredictable. This law helps for
scientists and students alike to
determine an object’s motion.
Newton’s Law of Universal Gravitation
F = force of gravity
m = mass of object
r = radius = distance
between them
This law explains what
determines the strength of the
gravitational attraction between two
objects or more. At least one of
these objects would have to have a
very large mass (like a moon,
planet, or star) for the effects of
gravity to be felt.
In summary, the law shows that the
gravitational attraction between 2
objects depends on their masses
and the distance between them:
Small masses and far away = weakest
gravity
Small masses and close OR
Large masses and far away = weak
gravity
Conclusion
Isaac Newton was a great scientist. He
did not follow his dreams, but became
something greater than he would have
been. He created the three laws of
motion, which without, the astronomers
and scientists today would have a
tough time studying the stars without.
The first law of motion means that
objects have a tendency to keep doing
what they were doing before continually.
They resist change, and if force is not
unbalanced, the object in motion will
stay the same. The second law means
that heavier objects require more force
to move than lighter objects. It also
means F=MA or Force = Mass x
Acceleration. Newton’s third law means
that for every action or force there is
equal size, with an opposite direction.
Newton’s laws give many people a
good understanding of how objects
move and reaction to forces on objects.
Newton was a successful scientist, and
his laws still live on today.
