Hi Everyone,
We've talked about the two kinds of heat transfer today: conduction and convection. Here are the notes that I made before today's class on these topics. If you need the diagrams, come see the transparent in the classroom!

For Monday's exam, think about the following materials:
1. Kinematics: distance, time interval, displacement, speed, velocity. Which ones are scalar/vector; how to calculate them; how are they related from one to another.
2. Kinetic energy: depends on velocity and mass. Its unit is Joules. You will be asked to do calculation.
3. Potential energy: depends on mass, gravity, and height. Its unit is Joules. You will be asked to do calculation.
4. Lab: What we did in the free fall lab. What is the purpose? What did we measure? How did we measure (ticker tapes)? Why are potential energy and kinetic energies different? (sound/heat + human error of pulling)
5. Temperature and thermal energy: thermal energy is the sum of particle kinetic energy, and temperature is the average of particle kinetic energy. Conduction and convection: how are they different? what are some examples of them?
If you have any question, please let me know!
Mr. T
