SPM Physics

Isaac Newton a 17th century scientist who is a very prominent figure in the world of physics. His theory & laws had been widely used till now and  it even helped  us to enjoy the rapid development of Formula 1 racing technology.
We are now living in a post IT society which is full of entertainment. We are able to do almost everything through online i.e playing games, facebook, shopping, watching movies etc. Those days in 17 th century, they don't have many entertainment as what we're having now. I would say the best entertainment for them are to seek more knowledge as possible. They don't have youtube, facebook, PS3, or among the worst Datuk T's pornographic movie. In other words they were not distracted with all these time wasting stuff.


Sometimes i 've been thinking that being a knowledgeable person at those days could be like a Hollywood artist. People will respect & adore them. In fact, this was the century where gifted persons like Isaac Newton, Galilieo Galilei, Blaise Pascal managed to revolutionalize their society towards seeking knowledge.That's why once they 've founded a principle or laws, they would place their names for us to appreciate until the end of time.

As for today, i want to discuss one of his laws that we will learn in SPM. It is the Newtons 1st Law of motion. Usually when we refer to this law,SPM students are more familiar with the term inertia. So what do this law tells us?

Newton's 1st law of motion often stated as:
An object at rest has tendency to stay at rest and object in motion stays in motion with the same speed and in the same direction UNLESS there is unbalance force acting on it.


Allow me to make it easier for u to understand. Its like this, all objects tend to '"keep on doing what they're doing" unless there is 'unwanted Force' yang kacau. For example, imagine it's a school holiday and your mom try to wake you up solat subuh. In this case, u have a 'big tendency' to remain on your bed, unless your mom pour a bucket of water on your face :) ..So the bucket of water will be the 'unwanted force'


Let me give u another classic analogy. If u are a noble, honest & never watch pornography in your life, then u should maintain your 'inertia' i.e your dignity eventhough there is unwanted forces like 'Mr T' who tempted u to watch sex ,lies & video tape (:


To understand better on concept of inertia or Newton's 1st law of motion,u should watch all these videos.
