revisited some of the worked examples from yesterday solving them with constant acceleration equations instead of graphs
discussed a host of projectile problems including launch at an angle
developed the range equation for a projectile launched from ground to ground...also developed an expression for height of projectile (given, vi, theta, and g)

developed the range equation for a projectile launched from ground to ground...also developed an expression for height of projectile (given, vi, theta, and g)...lecture video here
discussed a problem in which a projectile is launched at an angle off a cliff (very involved mathematics)...lecture video here
introduced circular motion bywatchingvideoon tumble buggy moving in circular path due to being tethered by a string to a poleFor each experiment, fill in the blanks in the tablebelow 8. Assume that the frictional forces exerted on all three objects are negligible and that the objects move at constant speed.Today's Recording is in item #5 above

students should be introduced to circular motion by watching video on tumble buggy moving in circular path due to being tethered by a string to a pole
For each experiment, fill in the blanks in the table found in the Google Doc attached to today's Google Classroom Assignment. Assume that the frictional forces exerted on all three objects are negligible and that the objects move at constant speed.

Today, students are going to conduct a Pivot Interactives Lab: Exploring Forces in Circular Motion-Reboot. Mr. Spencer will conduct a brief lecture on linearization and preview the activity...the students will participate in collecting data for the lab. There are three investigations in the lab and students are required to complete two of the three investigations. The investigations are: (a) force vs. radius; (b) force vs. mass; (c) force vs. speed. You will do the two investigations based on your birthday. If your birthday is Jan-April, do investigations (a) and (b)........If your birthday is May-August, do investigations (a) and (c).......If your birthday is September-December, do investigations (b) and (c). You must however, watch how the Pivot tools work for all three investigations in the prelab.
Make sure you have linearized your graphs (if necessary). Please have one of your two investigations completed before the end of class. Please have this entire activity done before midnight. You may ask questions during class (I'll be monitoring) or you may use the Google Classroom assignment question thread.

discussed results of yesterday's Pivot Lab -- Fc=Fnet=mv^2/r
discussed displacements, speeds, and acceleration for uniform circular motion
discussed conversions from rotational to rotational and from linear to rotational
discussed different forms of Fc other than mv^2/r
discussed a car going over a circular hill
students should watch the following videos in order: Centripetal Force Introduction (5:25 in length) ; Introductory Centripetal Force Problem-Car Over a Hill (7:30 in length) ; What is the Maximum Speed of a Car at the Top of a Hill (3:48 in length)
homework for today is to watch the first two circular motion videos from AP Classroom (I'll show you how)
