So I think almost all of you know the answer to my last question in last article  – Why you fall when a moving vehicle stops suddenly ? To those not known I will explain it very briefly.

It is also due to inertia. As in the just previous article when bus is moving all passengers will have the velocity of bus. The legs of standing passengers will also have the velocity of bus. So when bus stops suddenly their legs come to zero velocity. Due to inertia their body will try to travel with the velocity of bus. What happens then? Leg stops and body travels !!!  Obviously you will fall forward hitting your nose. Here also to escape , just hang by lifting your legs from the floor of the bus.

Now is there any other application for inertia in your daily life ? Oh….All thing inertia and inertia. Is some one murmuring ? But I will have to say one more from your daily life and put a semicolon for this inertia.

You might have witnessed the children’s play “touch me”. Some one is assigned as touch man.  He will run after others to touch them. When he runs behind the runner do not run in straight line. But moves in a zigzag manner. Hence the touch man will not be able to touch him easily instead he goes straight passing the running man. Before turning and coming back running man will have gone in another direction. The same effect is there in football matches when a player dribbles another one through different body actions.

What is the running man actually does ? He applies the inertia of motion. The chaser will be running fast behind him. When he suddenly changes his direction due to inertia the chaser will continue on his straight path without able to change his direction suddenly. So he goes passed!!

The effect will be very clear when a thick man chases a thin man. Fat people will have more inertia. So they will not be able to change their direction immediately. Next time when you or your children plays this game just watch the situation.

This theory is not only used by humans but also by animals also. When an elephant chases a rabbit , rabbit jumps here and there in a zigzag manner and escapes very easily. Poor elephant will not be able to control himself due to high inertia owing to his mass and goes straight. Who taught rabbits to apply this law of inertia ? Yes God is the creator.

Now next time, when you are walking through a forest and suddenly a wild animal begins to chase you . If it is not a dream you must run in a zigzag manner to save your life . Never run in straight path. If it is a dream just wake up to escape !!!

So till next time wish you a happy dream. If you have experiences like these please share it here.
