## Applying Law of Gravity to Judo

Written by Balaji B

In judo it is important to throw your opponent by making use of his loss of balance, law at work here is law of gravity. We know that Sir Isaac Newton discovered law of gravitation by seeing an apple fall from a tree. All bodies in universe attract one another. For instance, earth attracts bodies near and around it. In turn they also pull earth.

Since power of attraction, according to Newton, is proportional to mass of body that attracts, larger mass of body, larger its attraction. All bodies near earth fall to earth because it has an immense mass. An airplane or a bird starts to fall to ground as soon as its power of flight is exhausted. The force of attraction between earth and a two-pound weight is twice that between earth and a one-pound weight.

The attraction between earth and a body is called gravity. When gravity is represented by weight units, it is called weight. Now let us consider application of law of gravity to judo. The heavier opponent, more difficult it is for you to move him horizontally. It is even more difficult for you to move him vertically. On other hand, a larger gravity acts on him to make him fall.

In judo gravity may be represented as a force pulling opponent downward. If you want to make him fall, you make him lose his balance;that is, you cause his center of gravity to go outside base. Then gravity that acts on him works for you to make him lean or fall. Let us study action of law of gravity by illustrations.

Lets assume that you and your opponent are standing face to face. When your opponent advances towards you to take hold of you by left lapel. At same time you withdraw as much as your oponent advances. If your oponent is mentally or physically unable to let his advanced foot advance again, he will lean forward, lose his balance, and fall.

## 7 Tips for the Advanced Bowlers

Written by Balaji B

Once you have mastered bowling's fundamentals, you will find that there are many subtleties of approach and delivery that still may be something of a mystery to you. Be heartened by fact that even most advanced bowling stars have scoring problems. Some of most common of these are listed below:

1) ALLEY SENSE Bowlers too often "fight" lane. The ball either hooks too much or it won't hook at all, so try to adjust to lane conditions.If you feel you are releasing ball properly and ball still won't hook, there are a number of adjustments you can make: a) move slightly to right of your normal stance position; b) attempt to slow up speed of your ball, thereby giving it more traction; and c) try changing your target to a point inside second rangefinder.

You may move it in as far as third rangefinder (from right). Experience will show you proper adjustment to make. If ball is hooking too mucjh try one of following: a) move your starting stance slightly to left using your same target, b) try picking a spot further down lane to use as your target, or c) increase speed of your ball.

2) TEN-PIN LEAVES When ten pin remains on what seems to be a good pocket hit, fault generally lies with bowler. Experts in sport feel reason for it is that ball doesn't have enough rolling action when it strikes 1—3 pocket, or ball may be traveling at too great a speed when it hits pins. If you are bothered by ten-pin leaves, try giving ball more roll, less spin, and less speed.

3) POCKET SPLITS Many bowlers are bothered by troublesome splits that occur on what should be 1—3 pocket hits. If this happens to you, it is an indication that ball is "quitting"—failing to finish in proper rolling fashion. Usually this is caused by thumb coming out of ball too late. As a result, ball is given inadequate finger lift. To overcome this failure, shift position of your thumb in ball—bring it up to at least nine o'clock.
