Solving a proof on an exam and looking for possible resources to bring to it

Click For Summary
SUMMARY

The discussion centers on preparing for a challenging physics exam that includes a proof component. The exam covers the first four chapters of "Fundamentals of Physics 9th-Halliday," focusing on Measurements, Motion along a Straight Line, Vectors, and Motion in Two and Three Space. The participant plans to bring resources such as "Physics Problem Solver" and "Physics for Dummies" to aid in their preparation. A specific proof mentioned is the "apple and archer proof," which demonstrates that an arrow fired at a falling apple will always hit it if both are released simultaneously.

PREREQUISITES
  • Understanding of the Work-Energy Theorem
  • Familiarity with centripetal acceleration (v²/r)
  • Basic concepts of projectile motion
  • Knowledge of vector analysis in physics
NEXT STEPS
  • Research the "apple and archer proof" in detail
  • Study the Work-Energy Theorem applications
  • Review examples of proofs in classical mechanics
  • Explore additional resources on vector analysis in physics
USEFUL FOR

Students preparing for physics exams, educators seeking proof examples, and anyone interested in understanding complex physics concepts and their applications.

Have my first physics exam Thursday which I am told consists of 6 questions and one proof.
I am curious on thoughts of what a proof on an exam may consist of, and it there is any pages or books I could reference to give me some basic proofs or ideas of what I may see on the exam and how to work them out.

For the exam I am allowed to bring in any book or paper material to which I desire, so anything but a computer, phone, etc...I plan to bring Physics Problem Solver, Physics for dummies, and My textbook: Fundamentals of Physics 9th-Halliday, to which the test is on the first 4 chapters: Measurments, Motion along a straight line, Vectors, Motion in two and three space. So if anyone could help me with what possible proofs may lay in waiting or recommend any other resoursces I could bring to this exam, please do so. My teacher promises, and I have heard nothing other than, his exams are extremely difficult and consist of very complex problems, and will be nothing short of miserable for everyone. We are given an unlimited amount of time to finish the exam, but I don't feel like staying there and working on it all night.

Thanks in advance for any advice or insight.
 
Physics news on Phys.org
Work-Energy Theorem.

Centripetal acceleration = v2/r towards the center if the circle.
 
The only proof I can think of off the top of my head is the apple and archer proof; the question is here: http://www.alexpleasehelp.com/online/problems/arrowapple"

To make it a proof, you basically have to show that as long as the arrow is fired at the apple at its starting position, and both the apple drop and the arrow is fired at the same time, the arrow will always hit the apple.

Hope this helps.
