Force Friday Nov 30th

Take a look at these following videos.

1) Identify the type of motion (at rest, constant velocity or accelerated).
2) Draw free body diagrams for the object(s) of interest at various key points in time.
3) Describe the motion using Newton's laws.

If you are unfamiliar with the forces at play, still identify them as a result of the objects motion.

Thermal Physics - Function of a fridge

Here are some resources to help consolidate concepts related to the function of a fridge.

We will have a short quiz on the topic Monday of next week.

Force Friday Nov 2

Hello all,

To review today and remind about the homework.

1) create your table for free body diagrams for all important moments (transitional between types of motion) for a bungee jumper. See this video as reference.  (turn sounds down.....)

Crazy!!!!!! 

The bridge we talked about in class.

2) watch this commercial and talk about the physics of pulling out the table cloth without making a mess..

Have fun!
