Answer 1

Physics is the study of nature and its laws. We accept that all these different events in nature take place according to some basic laws and revealing these laws of nature from the observed events is Physics. For example, the orbiting of moon around the earth, falling of apple from a tree and tides in a sea on a full moon night can all be explained if we know the Newton's law of gravitation at Newton's Law of Motion.

The great physicist Dr. Richard Feynman has given a wonderful description of what is “understanding the nature” suppose we do not know the rule of chess but are allowed to watch the moves of the players. If we watch the game for a long time, we may make out some of the rules. With the knowledge of these rules we may try to understand why a player played a particular move. However, this may be a very difficult task. Even if we know all the rules of the chess, it is not so simple to understand all the complication of the game in a given situation and predict the correct move. Knowing that basic rule is, however, the minimum requirement if any progress is to be made.

One May guess at a wrong rule by partially watching the game. The experience player may make use of the rule for the first time and the observer of the game may get surprised. Because of the new moves some of the rules are guessed at may prove to be wrong and observer will frame new rules.

Physics goes the same way. The nature around us is like a big chess game played by nature. The events in the nature are like the moves of the great game. We are allowed to watch the events of nature and guesses the basic rules according to which the events take place. We may come across new event which do not follow the rules guessed earlier and we may have to declare the old rules inapplicable or wrong and discover new rules.

Physics, science that deals with the structure of matter and the interactions between the fundamental constituents of the observable universe. In the broadest sense, physics (from the Greek physikos) is concerned with all aspects of nature on both the macroscopic and submicroscopic levels.
