With your (almost) birthday buddy try these two problems. You don’t need to screenshot it, just call me over and show me.

• Static Equilibrium Problem (make sure you pay attention to which angle they are giving you)
• Forces in an Elevator (think about drawing a free-body diagram for each section of the force graph. What is the net force?)

You can draw your crime scene sketches and answer the questions on a piece of paper rather than typing it if you prefer.

We’ll be doing some video analysis of a rolling ball in Capstone today. Woot woot.

• Rolling ball video
• Falling ball video

For the analysis of the video that you make with your partner:

• Look at the horizontal position vs time graph.
  • What is the general shape of this graph? What does that mean?
  • What is the slope of the line? What does that mean?
• Look at the vertical position vs time graph.
  • What is the general shape of this graph? What does that mean?
• Look at the vertical velocity vs time graph.
  • What is the slope of this graph? What does that mean?

Play the Motion Terminology Self-Test! You must get 10 answers correct in a row. If you get one wrong, you will have to restart the whole thing.

Ok, now try this one: Finding Velocity from Position Graph
