Politics refers to a set of activities associated with the governance of a country, or an area.

1. Physical development:- Development of organ systems such as circulatory system, nervous system, muscular system, digestive system etc.
2. Mental development:- Physical activities require alertness of mind, deep concentration and calculated movement. This objective is related to the mental development of an individual.
3. Social development:- This objective is related to the development of social traits, which are essential for better adjustment in life. it is a better source for attaining the qualities like. Co-operation, fair play, sportsmanship tolerance and sympathy.
4. Neuro Muscular Co-ordination:- This objective is centered with a better relationship between nervous system. Education provide ample opportunities of physical neuromuscular coordination.
5. Emotional Development:- The emotional development of an individual is also the major objectives of physical education every individual has various types of emotions viz. Pleasure, hope, jealously, hateredness, fear, depression, anger, wonder, lust loneliness etc.
6. Development of Health: This develops health related habits through health education. This also provides education about the prevention of communicable disease.

In order to maintain uniform circular motion of a particle, a force is needed because uniform circular motion is an accelerated motion. The force is known as the centripetal force. Thus, centripetal force is the force required in order to make an object move along a circular path with uniform speed. The force acts along the radius and is directed towards the centre of circular path.

We know that centripetal acceleration of a particle moving with a constant speed v along a circle of radius r is given by
{tex}a _ { c } = \frac { v ^ { 2 } } { r }{/tex}
Hence, according to Newton's second law of motion, for a particle of mass m, we have
The centripetal force F = ma_c = {tex}\frac { m v ^ { 2 } } { r }{/tex}
As v = r{tex}\omega{/tex}, where {tex}\omega{/tex} is the angular velocity of the particle, then
F = {tex}\frac { m } { r } ( r \omega ) ^ { 2 } = m r \omega ^ { 2 }{/tex}

1. The process began during the national struggle for freedom.
2. First draft 1928, then 1931. Motilal Nehru and 8 leaders demanded in the draft: universal adult franchise, social justice, right to freedom and liberty.
3. Participation in Provincial Legislatures helped Indians in framing their constitution.
4. Leaders inspired by French Revolution, British parliamentary system and the Bill of Rights of the US.
5. They also learnt what the British were denying Indian citizens.

Law of multiple proportions (John Dalton 1804) states that when two elements combine to form two or more compounds, the weight of one of the elements which combines with a fixed weight of the other, bears a simple whole number ratio. For example, hydrogen and oxygen combine to form two compounds H₂O (water) and H₂O₂(hydrogen peroxide). In water, Hydrogen 2 parts and oxygen 16 parts In hydrogen peroxide hydrogen 2 parts and oxygen 32 parts.

The weights of oxygen which combine with same weight of hydrogen in these two compounds bear a simple ratio 1 : 2. Nitrogen forms five stable oxides:

N₂O Nitrogen 28 parts Oxygen 16 parts
N₂O₂ Nitrogen 28 parts Oxygen 32 parts
N₂O₃ Nitrogen 28 parts Oxygen 48 parts
N₂O₄ Nitrogen 28 parts Oxygen 64 parts
N₂O₅ Nitrogen 28 parts Oxygen 80 parts

The weight of oxygen which combines with same weight of nitrogen in the five compounds bear a ratio 16 : 32 : 48 : 64 : 80 : or 1 : 2 : 3 : 4 : 5.

• Fossils are preserved remains of living organisms from remote past.
• Fossil mainly preserves only a portion of the dead organism (eg: skeleton, bone, teeth etc..)
• Fossils may vary from microscopic (single bacterial cell) to dinosaurs.
• Layers of fossils are formed one after another over years. Deeper the layer where the fossil is found, older it is.
