Presentation Transcript

  1. Physics 211 Review

  2. Kinematics -1D • Know: definitions/meaning instantaneous velocity and acceleration • Graphical interpretation: slope of x,t and v,t curves • Area under v,t curve  x etc • Constant accel formulae: v=u+at, s=ut+1/2at2 etc

  3. Kinematics – 2D • Velocity tangent to path • Accel – 2 components – radial v2/r (centripetal) and tangential – rate of change of speed • Know about adding/subtracting vectors graphically

  4. Forces • Free body diagrams, labelling - FAB • Types: normal N, tension T (massless string), friction F< m N, weight W • Newton’s laws • Fnet=ma, F12=-F21 • Internal/external forces

  5. Work, momentum etc • F.Dx constant F – scalar product of vectors • W-KE theorem: net work done on body equals change in K=1/2mv2 • Impulse I=FDt  net impulse on body gives change in momentum p=mv • Conservation of momentum (collisions)

  6. Rigid Bodies • Center of mass CM, equilibrium: Fnet=0, tnet=0 (torque) • For object on pivot – equivalent to positioning CM at pivot – eg beam problems • Angular velocity and acceleration

  7. Pressure liquids and gases • P=rgh – yields force F=PA through any surface at depth h • Atmospheric pressure • Ideal gases: PV=nRT – n number of moles N/NA • Microscopic interpretation

  8. Thermal Physics • Gases in cylinders: work done on gas –W=-PDV • Heat flow into gas Q • First law of thermodynamics • DU=Q+W • U is internal energy (proportional to T for ideal gases) • PV diagrams, cycles

  9. Final • Friday 13 Dec 10:15am -12:15pm here • Comprehensive. (NOT Oscillations, Newtonian gravity, relativity). One sheet of formulae allowed • Practice exams + solns online • Review session – Tuesday 10 Dec 11:30-12:50 Stolkin (seating posted)
