Growing up‚ Von Braun‚ read a lot of Sci-Fi and became obsessed with the idea of Space Travel and since he was a small child he messed around with toy rockets and such. In 1930 he attended Technische Hochschule Berlin‚ where he got a degree in Mechanical

India has launched 74 artificial satellites in space .Here are some of them- Aryabhatta It was indias first satellite.It was launched by the Soviet Union on 19 April 1975[1] from Kapustin Yar using a Kosmos-3M launch vehicle. It was built by the Indian Space Research Organisation (ISRO) The launch came from an agreement between India and the Soviet Union directed by U.R. Rao and signed in 1972. It allowed the USSR to use India ports for tracking

theory they should both strike the ground at the same time; in practice the brick will always strike the ground first. The reason is because of air resistance. As the paper falls to the ground air resistance is pushing the paper up‚ this slows the acceleration of the paper. It is known that as the velocity of an object increases the air resistance acting on the object increases. If we consider jumping out of a plane and free fall towards the Earth the F.B.D. would be as follows: Now the force

A firework is an incendiary device or material that can be used forsignalling orentertainment. There are chemicals located in the nose ofthe rocket that explode‚ producing the colours seen. The art of fireworks‚ first originated in ancient China‚ with thefirst explosive being made from a mixture of black powder during theSung dynasty. It is believed that the explosive mixture was created bya combination of sulfur‚ saltpeter and charcoal. The Chinese foundthat the combination of these ingredients
