S=ut+1/2att. By the graph and mathematical process

Mandeep Kaur 4 years, 5 months ago

Why do we have to use the s=ut+1/2 at^2 formula? The mathematically proven equations are as follows (1) First equation of Motion: V = u + at soln. Consider a body of mass “m” having initial velocity “u”.Let after time “t” its final velocity becomes “v” due to uniform acceleration “a”. Now we know that: Acceleration = change in velocity/Time taken => Acceleration = Final velocity-Initial velocity / time taken => a = v-u /t =>at = v-u or v = u + at This is the first equation of motion. (2) Second equation of motion: s = ut + 1/2 at^2 sol. Let the distance travelled by the body be “s”. We know that Distance = Average velocity X Time Also, Average velocity = (u+v)/2 .: Distance (t) = (u+v)/2 X t …….eq.(1) Again we know that: v = u + at substituting this value of “v” in eq.(2), we get s = (u+u+at)/2 x t =>s = (2u+at)/2 X t =>s = (2ut+at^2)/2 =>s = 2ut/2 + at^2/2 or s = ut +1/2 at^2 This is the 2nd equation of motion. Hope u got it.

Parliament in India is not Supreme but the constitution is supreme

Posted by Prajapati Dhruv 4 years, 5 months ago

Sia ? 4 years, 5 months ago

Parliament is a legislative body which performs the function of deliberation and law making. Constitution on the other hand is the magna carta, Constitution enshrines the rights of individuals, it encodes the procedure of operation of business in the Houses of Parliament and is the fundamental law of the land.

The Parliament has rights to make laws but they can’t violate the constitution in doing so. The constitution acts as guide to the executive, legislature and judiciary. Constitution being the framework of our democratic system of existence is non violable. Constitution is the charter of the aspirations and ideals of people which is fundamental to the our democratic government. Constitution provides for the cautious separation of power among the various pillars of government viz. executive, legislature and Judiciary to implement the system of checks and balances so that none of them violate other’s sphere of existence and thus making the government stable and long lasting.
