LAW OF MOTION

Maybe you don't know there are many objects are moving at your own surrounding.Sir Isaac Newton [1643-1727] has given us a new and fundamental basics in physics about motion after Aristotle thinks that objects after moving,then stop due to supporting from removal air from the rear.Galileo Galilei then noticed the mistake and he[Newton] expanding the theory and create the law of Inersia.

#1 INERSIA

-Inersia: Nature which has retained the object at it's own speed/position IF there aren't any force that imposed from outside.

-The Law of Inersia: If the force are not imposed to an object,the stop- motion object,would be stationary and always stops.While the object that always move,it always move towards.

Example:The movement of the vehicles,objects and someone and flip of a curtain.

#2 F=MA

-The more force imposed,the more changes of the velocity.F=MA means Force=mass*acceleration.If the acceleration is imposed to an object,the net force will directly proportional to magnitude way of net force,in same direction,it will inversely proportional to the mass of an object.

Example:Movement of an object

Example:Timmy's car mass is 450 kg.The acceleration of the car is 0.15 m/s*2.What is it's force?
Answer:450 kg *0.15=67.5=6.75N

#3 The different reaction

When the magnitude of direction is same,the reaction will be opposite/same[equal],that is law of motion and reaction.

Walking

Let me give you the way to understand it.




Timmy wants to sail with his boat.In this case,Timmy is the action while the boat is the reaction of Timmy's action.

THE VOYAGER'S SIBLINGS

In late 70's, extreme rare event was held at the orbits of outer planet of Solar System;Jupiter,Saturn,Uranus, Neptune and Pluto aligned such a way that could possibly for a pair of spacecraft to travel,visit and study about them.
-To take benefits of this once in every 175 years chance,Almost 4 decades later,the rickety old probes still travelling and making discoveries push forward the boundaries of science.

The Dwarf Sons

After the Solar System,there is a belt that is the final frontier of our space System.It was called THE KUIPER BELT.It looks like a disc-shaped region of icy debris for about:6-7.5 billion km[3.7-4.6 million miles] from THE SUN.There are 1000 objects in the Kuiper belt has been discovered,almost from '92.
