Free Physics II Tutoring Available in NPB 1100 | Room Hours and Important Info

Join us for free tutoring in Physics II (PHY 2049) at NPB 1100, Monday to Friday from 10:00 AM to 3:00 PM! Ensure you’ve resolved all WebAssign problems and come see me right after class for any remaining issues. Remember, mastering physics concepts—like working with electric potential and understanding the principles of force, work, and energy—is achievable with practice. Don't hesitate to try and practice as often as you can; just like learning a bicycle trick, you'll get there!

Presentation Transcript

  1. PHY 2049: Physics II • Tutoring Center is open in room NPB 1100, M-F 10:00AM -3:00PM. It is free. • Hopefully all webassign problems have been solved. Please see me immediately after the class if there is still an issue.

  2. PHY 2049: Physics II • About bicycle riding: If some one shows you a trick, it means that, • It is possible to do that trick • The person who showed you, can do the trick. • It does not mean that you can do the trick. • Try it a lot of times and you can too.

  3. PHY 2049: Physics II • Force => work => change in K=> change in Potential energy • ΔU = Uf – Ui = -W = - ΔK • Work done is path independent. K+U = constant. U = k q1 q2/r

  4. PHY 2049: Physics II • Electric Potential • V = U/q = -W/q • Units of Joules/coulomb = volt • 1 eV = e x 1V = 1.6 x 10-19 J • Also • V = kq/r • Vf –Vi = -∫E.ds • Add as a number

  5. PHY 2049: Physics II

  6. PHY 2049: Physics II • Rank them by the magnitude of electric field • Which has the field pointed to the right • What does an electron do when released midway

  7. PHY 2049: Physics II

  8. PHY 2049: Physics II • Vf-Vi = -∫ k q/r2 dr • Choose Vi = V (∞)=0 • V(r) = kq/r

  9. PHY 2049: Physics II

  10. V = kpcosθ/r2 • E = -∂V/∂s = - • Uniformly charged disk • V = ??
