I was in a bus, and it stopped suddenly, so a man fell to the ground, then I was wondering why did he fell straight ahead. Therefore, I made some researches and I found out that it is due to his INERTIA, not just him but all the passengers have jerked forward (even me),but they all tend to remain in their state of motion, even if the bus has come to rest. So I have realised that INERTIA or NEWTON’S FIRST LAW is one of the most important phenomena in the history of physics, and then I decided that it’s the topic I will talk about.
