PHYS 101/121 LAB
2018 Fall 101/121 LAB Notes
EXPERIMENT 1: THE SIMPLE PENDULUM
- A wonderful book for 'Dimensional Analysis' and other great stuff: 'Street Fighting Mathematics' (Sanjoy Mahajoy) [Open Access]
- Why do we round 5 up when the digit before is odd and vice versa? Wikipeadia article - Round to half-even
- Solution for the large angle amplitude for the 'simple pendulum'
- For fun: Simple Pendulum is boring! What if you combine two pendulum and get a 'Double Pendulum' - see the Youtube video
EXPERIMENT 2: FORCE AND ACCELERATION
- Analysis of experiment data with a programming language Python (Jupyter Notebook) - Github Link
- History: 'Is Newton’s second law really Newton’s?' (American Journal of Physics)
- Advanced read - Whence the Force of F = ma? Frank Wilczek (Nobel Laureate) [Advanced discussion of force and Newton's second law and its drawbacks in the light of modern physics; it is OK if you don't understand most of it, good to get a gist of modern physics.]
- EXPERIMENT 3: BALLISTIC PENDULUM - PROJECTILE MOTION
- Some historical account of how Galileo experimented with the projectile motion with its original drawings: "Galileo's work on projectile motion"
- Detailed experimentation with our spring-gun set up with some analysis from a nice blog; you should definetly check it:
- "More Measurements of the Projectile Velocity"
- "More projectile motion than you can shake a stick at" - Dependence of the initial velocity of the ball with respect to prjectile angle
- and some fun video! Cannon Firing in Slow Motion - The Slow Mo Guys (Youtube)
