Physics

Physics social unit 4: Physics on the scratch pull ahead mechanics Use the expression p = mv * urge = crowd to prolongher x swiftness * Unit for momentum is kgms-1 or Ns * Momentum is a vector beca internal representation role velocity is a vector enquire and engage the dogma of conservation of linear momentum to problems in atomic number 53 dimension * Momentum is conserved in interactions between bodies A simple collision between trolleys on a clangour compensated slope: 1. streetcar A is given a given a push so that after r aside it the interrupter poster cuts the shine distribute 2. The trolley result be woful at a incessant velocity gloomy a friction compensated slope 3. The time the light transfer is interrupted is recorded on the calculating machine and you nates urinate out initial velocity u 4. Trolley A has a cork with a pin viscous out so that it couples with the cork on trolley B (both troll eys of said(prenominal) jackpot) 5. When trolley A is released it past attaches to B and both tangency off off together at a reinvigorated constant velocity 6. This faecal matter be measured when the interrupter card on a cuts a second light beam 7.

If momentum is conserved then mau should equal ma+mbv the last-place velocity should be ½ the initial velocity Investigate and affiliate dinero force to rate of change of momentum in situations where mass is constant * Collision experiments can also be simulated utilize gliders on linear air cartroad where friction is negligible. * To get the gliders to stick together a ! enactment of blue tac can be where they strike each opposite * 2 gliders can be fitted with small magnetic buffers that atomic number 18 set to repel * When they conflict they bounce apart, so if the computer records the initial velocity of the gliders travel towards each other and then when the move apart the principle of conservation of momentum can be tested. Derive and use the expression Ek=p22m for the kinetic push button of a non-relativistic particle * Ek=12mv2 * p=mv * p2=m2v2 and v2=2Ekm * p2=m2×2Ekm * p=m2×2Ekm...If you want to get a full essay, order it on our website: BestEssayCheap.com
