We all heard about the story of Newton's pleasant experience with a falling apple. It may not be the first time that the great man saw something falling in his life; it certainly was not the first time he saw a falling apple either. An idea, however, dawned upon Sir Isaac Newton when he saw that particular apple falling off a tree in his backgarden- a Eureka moment for Newton. It changed the way people perceived the world around them for ever: the theory of gravitation was born. It was intuition that made Newton understand what gravity was all about.

Newton's Apple

In addition to Newton's Law of Gravitation, he came up three laws to describe the motion of objects. They came to be known as Newton's Laws of Motion.

Newton's Laws of Motion

  1. An object is at rest or moves along a straight line unless it is acted upon by an external force.
  2. The rate of change of momentum an object is directly proportional to the force that caused it.
  3. Every action has an equal and opposite reaction.

Can you take the paper off the table without touching or toppling the bottle?

Bottle Trick

If you broaden the understanding of Newton's Laws, you can do it easily. First, try it with your friends as a challenge. If you can't, then watch the video to see how it could be done.

Friction - necessary evil

Friction is evil, yet essential. Those of us, who have experienced unglamorous falls on hardened snow in wintry months, know very well what could happen in the absence of friction.

Here is a clip that shows how coconut pluckers in Sri Lanka defy gravity, thanks to friction - impoverished, but ingenious. They reach the height of 6-7 double-deck buses in a matter of seconds to pluck coconuts!

What would you expect in the following scenario?

Balloon and Plank Puzzle


A balloon, which is filled with air, and a piece of plank float on the surface of the placid lake. They were dragged down deep into the water and then released. What would happen?

  1. Both will go down.
  2. Both will come back up.
  3. The balloon will go up and the plank down.
  4. The balloon will go down and the plank up.
