  4. 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

  5. discussed a problem in which a projectile is launched at an angle off a cliff (very involved mathematics)...lecture video here

  6. introduced circular motion by watching video on tumble buggy moving in circular path due to being tethered by a string to a pole

  7. Watch these videos of three experiments

  8. For each experiment, fill in the blanks in the table below 8. Assume that the frictional forces exerted on all three objects are negligible and that the objects move at constant speed.

  3. 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.

  4. 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.
