Kinematics is the

branch of physics that studies motion without its causes. It has always been very frustrating

because scientists are always speaking different languages which makes things

harder to understand. We have to say biology, which is Greek and Latin for

studying life. The deeper you go into the sciences, the more Greek and Latin

you’re forced to learn .At first, it seems like you’ll never get it all

straight but it is going to be easier. Throughout the history scientists and physicians have found laws in our

real life. Some were proven false, while others are used in today’s life which

really useful. A unique group of laws

for special mechanics are those suggested by Isaac Newton. “Laws of motion” which explains bizarre

things we haven’t ever known in our life. His first law of motion simply

explains that if an object and no net force is used to it ,will remain with the

same speed, which means that if it is not moving it will remain the same, and

if it is moving , it will be the same. If our speed is 4m/s then our speed will

continue 4m/s ,if our speed is 0m/s then our speed will be 0m/s. Newton’s second law is

more fancy. It tells us a force acting on an object will move that object in

the same direction as the force and . This gives us the familiar equation: a=. Acceleration is simply the

rate of change of the speed. Its Si unit is m/s2. From the

definition of acceleration, we can say that it is an important thing for the

kinematics. We can determine how far an object with an acceleration of “4 meters per second squared is after 10

minutes” by using 4 formulas which are really important . We can find also

acceleration by working backward, such as the case of an object “moving

200 kilometers in 2 hour with initial

velocity 0”. From the Newton’s law and

the 4 formulas we can find its acceleration.

Let’s look at a very common form of acceleration,

one that we are all exposed to, “gravity”. As many of us know our “theory of

gravity” also its explained by Newton. Newton worked out that the force between

two objects due to gravity was depends on to their mass and inversely depends

to their distance. This force, however, is quite small which means there is a

lack of attraction between two objects. The average of gravity of the earth is

10m/s2 (9.8m/s2). The third law states that every action has a

reaction with the same force but with different directions. in other words, if

object A exerts a force on object B, then object B also exerts an equal force

on object A. Notice that the forces are exerted on different objects. The third

law can be used to in different type of sciences especially in astronomy . Kinematics is used in astrophysics to

describe the motion of celestial bodies and collections of such bodies. Famous

scientists on the kinematics are :Galileo Galilei,Newton,Archimedis

Galileo Galilei

After his

censure by the Church, Galileo was placed under house arrest and was not allowed to study any other science. Instead he

started to focus in physics—where, ironically, he struck the blow that would

destroy the disaster scientific system caused by Rome. In 1638, he published

some books which got burnt by the Church,. In it, he laid the groundwork for

physics by emphasizing a new method that included experimentation,

demonstration, and quantification of results. The

character of Salviati didn’t like for

Galileo’s ideas and Simplicio for those of Aristotle, while the smartest

Sagredo sat by and made normal questions and comments. Through Salviati,

Galileo chose to challenge Aristotle on an problem that to most people at the

time seemed completely used to it: claims that the speed of an object which is

dropped by a distance varies from its weight. In order to proceed with his aim,

Galileo had to introduce a number of demonstration, experimentation, and

indeed, he established the sub discipline of kinematics, or how objects move.

Aristotle had said that when objects fall, they fall at the same rate of the

speed from the moment they begin to fall until they reach their “fixed”

position. Galileo, also, suggested a view of motion, unknown at the time, that

became an important part of studies in physics called acceleration.

Archimedes

The most

famous mathematician in the old ancient Greece was Archimedes ,well known in

sciences . Archimedes is famous for his invention

of the intercourse between the surface and volume of a sphere and its surround cylinder.

He is known for his formulation of a hydrostatic invention and a device for increasing water volume, which is really used in some

countries today, known as the Archimedes screw . He had

an important special role ,(that nobody else had it )in the defense of Syracuse

against the attackers laid by the ancient Romans in 213 BCE by building war machines so useful that they long delayed the capture of the city.

rous mathematical proofs 4–6. He fixed the capitals of plane and solid geometry. Some

of Archimedes’ machines were founded with

mathematical books. He invented the law of

simple machines like

1.lever-the three rules of lever

2.screw-

MA = (? * d) / l

3.winch –

P= Weight of Vehicle

4.pulley –

5.wedge

He also

invented the mechanical advantage ,which its formula is M=F*d.

Sir

Isaac Newton

Newton was a known figure in the scientific revolution, and arguably the

greatest mathematician and greatest physicist of all time because of its laws

in kinematics. Basic kinematics laws are suggested by Sir Isaac Newton .Most important formula of Sir Isaac Newton is W=m*g. Some people find out funny but the idea of gravity came when apple felt

in his head. The story goes that Newton saw an apple fall to the ground and it made

him wondering why the fruit always fell straight to the ground without changing

direction or anything else .Newton said that even from high distances, the

apple would still feel this force of attraction, although this is not that
