Key Concept(s) Today: Acceleration & Graphs
Pass out: 1. "Must Know Equations" 2. " AP Physics Study Guide & Review"
Journal:
Examples: 1. If you travel 10m/s due east for 20 s, what is your: a) Speed b) Displacement c) Velocity
2. If you travel 10m/s due east for 20 s, then you travel 20m/s for 20s due south, what is your: a) Speed b) Displacement c) Velocity
3. If you travel 10m/s due east for 20 s, then you travel 20m/s for 20s due south, then you travel 10m/s due west for 20s, what is your: a) Speed b) Displacement c) Velocity
1. a) Speed (Dist/time) = 200m/20s = 10m b) Displacement 200m due east or 00 c) Velocity = (Disp/time & Dir) = 200m/20s = 10m @00
2. a) Speed (Dist/time) = 200m/20s = 10m b) Displacement 200m due east or 00 c) Velocity = (Disp/time & Dir) = 200m/20s = 10m @00 3.
a) Speed (Dist/time) = 200m/20s = 10m b) Displacement 200m due east or 00 c) Velocity = (Disp/time & Dir) = 200m/20s = 10m @00
DEMO:
1. Draw a free Body Diagram of this ball on an incline plane.
2. Draw graphs (Pos vs Time, Vel vs Time, & Acceleration vs Time) for a ball rolling down an incline plane
