PHY 2060
Exam 2 — Fall 2007
Exam 2 will take place in NPB 1002 from 8:30 to 10:25 a.m. on Thursday, October 18. Please try to arrive by 8:25 a.m. You should bring writing implements, and you may use two formula sheets and an electronic calculator. No other papers or electronic devices may be used during the exam.
The exam will consist of 10 questions in a format similar to past semesters' exams (see the exams page for samples). Question 1 will be in multiple-choice format, while the remaining questions will consist of problems requiring a written solution. These questions may address any of the material covered in class through Thurday, October 11. The emphasis will be on material covered since the first exam. These topics are listed below, along with the most closely related sections of the text.
Applications of Newton's Laws
- Tension in strings (Sec. 5–2)
- Contact forces: normal forces, static and kinetic friction forces, analysis of rigid bodies in contact (Secs. 5–2 and 5–3)
- Dynamics of circular motion: the conical pendulum, the "rotor" amusement-park ride, the banked curve (Sec.5–4)
Momentum
- Linear momentum (Sec. 6–2)
- Impulse and change in momentum (Sec. 6–3)
- Conservation of momentum (Sec. 6–4)
- Two-body collisions: coefficient of restitution, types of collision (Sec. 6–5 and lecture notes)
- Relativistic momentum (Sec. 20–8) — will not be questioned on the exam
Systems of Particles
- Center of mass motion (Sec. 7–3)
- Center of mass of solid objects: calculation via (a) volume integration, (b) symmetry arguments, (c) decomposition, and (d) the "negative-mass" trick (Sec. 7–4)
- Conservation of linear momentum (Sec. 7–5)
- Systems of variable mass (Sec. 7–6)
