Physic - 8
First of all, I'm going to talk about what we did and I learnt on Thursday's science lesson(:On Thursdy, Mr Lim let us watch Home Alone. It was the first time of me watching it. Well, this is not the main point of today's post. In that movie, forces were used almost everywhere. There were tension used. Friction was against the rolling wheels. I believe everyone of us take forces for granted in our everyday lives, right? I'm not the exception too. Let's think about it this way, without forces, are we able to do work? The answer is no. Like for example. If there happens to be no gravitational force on eath at all, what would happen? We would be floating around the earth like nobody's business. Worst of all, we know that we living things need food and water. Without gravity, we won't be able to consume our food too! See how important forces are! However, there are harmful forces too. Such examples are: Earthquakes and volcano eruptions. These are terrible natural disasters. Weight is a force. Weight is a gravitational pull from the centre of the earth. Mr Lim pointed out some misconceptions within us too: The apple did not drop on Sir Isacc Newton's head. He SAW the apple dropping down the tree. Thanks Mr Lim(: Sir Isacc Newton, is the father of mechanic, statics and some other great dicoveries. He came from a very poor family. Isacc always self-studied, he was a genius. His father was poor and not educated. Therefore, when Isacc was born, his father did not know what to name his son. He then decided to name his son after his own name, Isacc Newton. According to Mr Lim, he said that debates were going on about whether Isacc was a gay or not. Was he really a gay? Does that really matter? What really matters is what the great scientist had contributed to the world, isn't it? Facts are facts, we can't change facts even if we continued debating. More over, that happened decades ago, what could be possible be done? I will blog about the 3 laws of motion later(: |
