Discus: The Other Frisbee Discus; a field event as ancient as the Olympics‚ is always underestimated. Many believe discus is an event in which you throw a disc like a Frisbee‚ but it’s not. There’s so much more. The so called Frisbee is actually a metal or rubber disc‚ which can vary in weight from 1 kg to 2 kg. In order for a throw to count‚ one must remain in the 8 ft ring at all times until the announcer says‚ “Mark!” Also‚ the disc must land in between the sector lines. The overall goal

The Universe and Our Galaxies The Universe and Our Galaxies Examples of Elliptical (Messier 87 ) and Spiral Galaxies (NGC 3559) Examples of Elliptical (Messier 87 ) and Spiral Galaxies (NGC 3559) Edwin Hubble was one of the first people to actually realise what a galaxy is‚ the measurement of the “Hubble Tuning Fork” Classification scheme shows how round or rightly wound their “arms” are. E0 means that an elliptical galaxy is extremely round‚ whilst E7 is flat. However not all galaxies

Partner: Florence Doval Due 16 November 2011 Aims: To use a centripetal force apparatus to calculate the moment of inertia of rotating weights‚ using theories derived from ideas of energy transfer (Im = MR2 (g/2h)(t2-t02)) and point mass appoximation (m1r12 + m2r22). Set Up Procedure First we measured the weights of two masses and wingnuts that secure them. Then we placed one of the masses on the very end of a horizontal rod on the centripetal force apparatus‚ 0.162 m away from the centre of the rod

Frances Ferguson calling it (the novel’s) “one and only formal contribution to literature”. One of the main characteristics of FID as described by Alan Palmer is its solipsistic or “centripetal” nature‚ allowing close scrutiny of not just a character’s actions‚ but of their very though processes. It is this ‘centripetal’ nature which drives the novels storyline‚ Emma’s continual misinterpretation of the world (revealed via FID) contrasted with the omniscient narration of Austen or Mr Knightley‚ allowing

constantly accelerating‚ a centrifugal force must be introduced in order for Newton’s Laws of Motion to apply. Centrifugal force is a useful concept in analysing behaviour in rotating systems and is the apparent force acting outwards to counteract the centripetal force. This apparent force results from an objects tendency to continue in a straight path due to its inertia. A simple model of the Space Elevator considers it to be a uniform free standing tower. This tower is not a compression structure however
