  1. Physics 1 – Sept 24, 2019 • P3 Challenge – • Add A = 16 N at 80 and B = 24 N at 245 analytically. • Get out 1.3 Practice problems for Homework Check MIT is coming!!! Friday from 10:30-11:15, A day. Sign up by Wednesday and get teacher approval.

  2. Objectives and Agenda • IB 1.3 Vectors • Adding vectors analytically • Agenda • Homework review • Vector Darts lab activity - a fun way to create a data set to practice vector component calculations. • Assignment: • Complete the Vector Darts Lab

  3. Vector Darts Procedure Overview • In pairs, with one trio. 9 groups. 3 teams per dart board to take turns. • Prepare a paper with a pair of axes with origin in center and y in the long direction. Label the +x and +y directions. Tape to dartboard with +y directly up and the origin in the center of the bullseye. Lean against the wall using a whiteboard backdrop. • Toss 10 darts against board from about 1.5 m away to create 10 holes in the paper. Try to hit the bullseye. Let all have a chance to toss the darts. (Practice tosses are allowed but pickup games are not! Others are waiting on you then there are calcs to do.) • The most accurateteam will get 5 pts extra credit. Any accurate end result calculation team (w/in 2 cm) will get 2 pts extra credit. • Draw lines between each of the holes and the origin of your axes. Number the holes 1-10. • Measure the (r, ) for each hole and record in the data table.

  4. Vector Darts Data Analysis • 1) Find the average r. (lowest will get 5 pts extra credit) • 2) Find the standard deviation of r. • 3) For each data point, determine the x and y components of the dart position. • 4) Find the ave x and ave y position for the average dart location. • 5) Find the st dev of the x and y data to assess their uncertainty. • 6) Determine the corresponding (r, ) for the average dart location. • Any rave < 2 cm will get 2 pts extra credit

  5. Questions overview. • 1-4 are about evaluating your x and y results. • 5 is an error propagation problem to find r. Additional help is available on separate sheet. • 6 – 9 are about evaluating your r result. • 10is about sources of error.

  6. Exit Slip - Assignment • None. • What’s Due? (Pending assignments to complete.) • Vector dart lab due in one week, on Tuesday 10/1 • What’s Next? (How to prepare for the next day) • Read p45-50 on projectile motion
