Motion
During Isaac’s
life he created ample things that’s help the human race to understand the
world. His work was recognised by people all over the world, these significant
things that he did include:
Laws of Motions
Isaac Newton had three laws of motion, these laws were published on July 5th 1687, when he was at the age of 24. The laws give a basic understanding of motion, these laws are seen as the fundamental building blocks of motion. Newton’s discovery of the three laws of physics enabled him to predict motion from the swinging of a pendulum to the motion of planets and galaxies. Newton’s first law
A body will stay at rest or at a constant speed in a straight line until an external or unbalanced force is acted upon it. Newton’s First Law can also be called The Law of Inertia. Examples of this Law include:

Imagine
you are in a car moving at a constant seed in a straight line. If the driver of
the car were to suddenly apply the brakes. You would feel as though you were
being thrown forwards. Actual your body has a tendency to keep on doing what it
is already doing, which is moving in a straight line at a constant speed. The
car however, is slowing down around you, and your seat belt (external force)
stops you from continuing to move forwards into the dashboard or through the
front windshield.
A
skate boarder is riding at a constant speed and a rock goes in the way of the
skate board and the skate board stops but the skate boarder continues to move
and eventually falls on his head. In this example the rock is the external/unbalanced
force and the boarder is the body moving at a constant speed.
Second Law (Newton’s
second law is represented as an equation)
Force (N) = Mass (M) X Acceleration (A)
Force is measured in Newton’s, in commemoration of Isaac Newton. In words 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. Example To push a chair it is easy, because the mass of the object is very little hence little force is needed, but to push a car it difficult, because the mass of the car is a lot, therefore more force needs to be applied.
Newton’s Third Law For every action there will always be an equal opposite reaction.
Example
A rocket's action is to push down on the ground with the force of its powerful engines, and the reaction is that the ground pushes the rocket upwards with an equal force.

Gravity
Newton publicised
his Theory of Universal Gravitation in the 1680s. It basically set forth the
idea that gravity was a predictable force that acts on all matter in the
universe, and is a function of both mass and distance. The theory states that
each particle of matter attracts every other particle (for instance, the
particles of "Earth" and the particles of "you") with a
force that is directly proportional to the product of their masses and
inversely proportional to the square of the distance between them.
So the farther apart the particles are, and/or the less massive the particles, the less the gravitational force.
The standard formula for the law of gravitation goes:
Gravitational force = (G X m1 X m2) / (d2)
G is the gravitational constant, m1 and m2 are the masses of the two objects for which you are calculating the force, and d is the distance between the centers of gravity of the two masses.

Optics
In 1664, Newton read
about optics and light from the English physicists Robert Boyle and Robert
Hooke. He investigated the refraction of light using a glass prism, over a few
years he developed a series of increasingly elaborate, refined, and precise
experiments. Newton discovered similar, mathematical patterns to his mentors
about colour. He found out that white light was a mixture of multiple colour
ray’s, each ray was found by the angle through which it was refracted on
entering or leaving a given transparent medium. He linked this idea with his
study of the interference of colours within thin layers (for example, of oil on
water, or soap bubbles), he did this by using a simple technique of measuring
the extreme acuity thickness of such layers. Newton was also able to conclude
that light consisted of streams of minute particles. From the experiments that
he did over the years he was able to gather the magnitudes of the transparent
corpuscles forming the surfaces of bodies, which according to their sizes, interacted
with white light rays. From these years Newton was able to gather sufficient research
to give other scientists better knowledge of Optics.
During
Newton’s life he used mathematics as a major tool in all his research,
experiments and discoveries. Newton made contributions to all branches of
mathematics then studied, but is especially famous for his solutions to the
contemporary problems in analytical geometry of drawing tangents to curves
(differentiation) and defining areas bounded by curves (integration). Not only
did Newton discover that these problems were inverse to each other, but he
discovered general methods of resolving problems of curvature. Newton also developed his own system of calculus,
which is a form of mathematics used to solve problems
in physics.
