Gravity


If we take an iron ball and a paper ball, both of the same size, and drop them simultaneously from the ceiling to the floor, they will reach the floor simultaneously. This was discovered by Galileo when he was making experiments with falling bodies at the Leaning Tower in Pisa.

Gravity is the attractive force by which bodies tend to the centre of the earth, but we are so used to this fact that we do not notice it. Gravity is characterized by acceleration.

Galileo found that the velocity of the falling bodies increases progressively. They travel 16 ft during the first second, 64 ft during the first two seconds, and 144 ft during the first three seconds.

Gravity does not work alone. Its "partner" is centrifugal force. Centrifugal force is the force with which bodies revolving round the centre tend to fly off. The earth "hangs" in space because of these two forces.

The gravity of the sun is the force which holds the earth and other planets in their places. If it should stop working one instant, the earth would fly away from the sun, the sea and everything else on the earth would spill off into space, and life would be destroyed immediately.
