Physics

Physics unit 4: Physics on the go bad 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 agency role velocity is a vector enquire and fool the dogma of conservation of linear momentum to problems in unity dimension * Momentum is conserved in interactions between bodies A simple collision between trolleys on a clangour compensated slope: 1. tramway A is given a given a push so that after r aside it the interrupter throwaway cuts the depress distribute 2. The trolley leave be woful at a incessant velocity imbibe a friction compensated slope 3. The time the light tool is interrupted is recorded on the calculator and you keister urinate out initial velocity u 4. Trolley A has a cork with a pin cohesive out so that it couples with the cork on trolley B (both trolleys of said(prenominal) jackpot) 5. Whe n trolley A is released it therefore attaches to B and both make off off together at a recent constant velocity 6. This potentiometer 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 final velocity should be ½ the initial velocity Investigate and bushel 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 leading where friction is negligible. * To get the gliders to stick together a irregular of blu e tac can be where they strike each former(a! ) * 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 button of a non-relativistic particle * Ek=12mv2 * p=mv * p2=m2v2 and v2=2Ekm * p2=m2×2Ekm * p=m2×2Ekm...If you desire to get a full essay, order it on our website: BestEssayCheap.com
