The Law Of LAW

In this Science of SCIENCE posts, I will be covering "The Law Of LAW". The laws are actually very easy. So, stick with me and we will travel one of the law, actually is there are three. However, we will still need to know the person who invented ----Isaac Newton

Isaac Newton

  Isaac Newton was born 25 December 1642 at Woolsthorpe, Lincolnshire, England. He had given a lot of contributions on Mathematics ,Physics ,Natural Philosophy, Astronomy, Alchemy and Christian Theology Economics (but we will focus on physics today). He died at the aged of 84 (20 March 1726) at Kensington, Middlesex, England, Great Britain.

Now the law part, There are three main law that we are going to focus

• Newton First Law Of Motion
• Newton Second Law of Motion
• Newton Third Law of Motion

Let's go back to the drawing block.

Newton First Law Of Motion

  Newton First Law of Motion is talking about inertia. What is inertia? Let's me back to basics. When Issac Newton invented this law, he said "When a thing is moving, it will be going in a straight line." However, there is a thing say this is wrong. Because frictional force and gravity will slow things down. So still, what is inertia? Inertia happened when a object is travelling at a speed and suddenly stop by a force. You will see that the object move forward a bit. This is inertia.

Application

  

  When the bus moves and suddenly stops, the people in the bus will move front.

Newton Second Law Of Motion

  We will learn about A Formula which is 

F=m*a

F (Net Force)

m (Mass)

a (Acceleration)

   It will explain what is net force and acceleration. Net force is the total force that act on an object while acceleration is how fast or slow an object is. And another thing, if a thing falls from midair, its acceleration is 10 m/s2.

Application

The student at the right use more force than the student at the left. It is because the heavier the stone, the more force is used to pull the stone.

 Newton Third Law Of Motion

  In this law, it's just talking about the force that act upon an object and the opposite force, Don't understand? Ok! let me break down. It's just like this. if you push a thing, there you be a pull force equal to the push force.

Application

  

When you punch the wall harder, you will feel more pain. It's because the force you puch on the wall is equal to the force that act on your hand.

Here you are! the three law of motion from Isaac Newton. I hope you will enjoy this post. Feel free to comment below. So, bye.
