Circular Motion Review

For all you folks hoping to review circular motion before the quiz tomorrow, here are a few videos that I found helpful in breaking down uniform circular motion.




Happy sciencing!

Momentum Lab Tasks

There are three videos that you will need to analyze for the lab tasks today.

  1. What is the change in momentum of the ball during the collision?
  2. What impulse is imparted on the ball during the collision?
  3. What is the magnitude of the average force of the wall on the ball during the collision?
  4. Do you think the force exerted on the ball is constant during the collision, or that the force varies during the collision?
  5. Can you make an estimate of the peak force on the ball during the collision? What assumptions do you make in the process of estimating?

  1. What is the speed of the M&M before the collision with the cart?
  2. How do you think the actual speed of the M&M compares with your predicted value? 
  1. What is the ratio of the mass of the boy to the mass of the paddleboard?
  2. If the mass of the boy is 32 kg, what is the mass of the paddleboard?

(AP Physics) Three Things

1) If anyone has any pictures or videos from tug of war today, send them my way!

2) Congrats 1B! Y'all scored mastered a ton of standards today. I still have yet to grade the question for STT.2, but everything else is updated on the Master Excel File and soon to be updated on PowerSchool.

3) I recently uploaded a step by step guide to drawing a free body diagram and solving for missing forces. Check if out if you're having trouble with this. Our balanced forces SA will be coming soon. I'll give you a specific date by Sunday.  To find the file, go to Files > AP Physics > 3 - BFPM > FBD Step by Step
