2D Motion with Horizontal Vi

Procedure:

Materials: ramp, meter stick, stopwatch, tennis ball, tape.

Step 1: Set up the ramp on the table, then set up the meter stick on the floor horizontally.
Step 2: Find equations of where the tennis ball lands on the horizontal stick.
Step 3: Test your calculations.

Analyzed Data:

Rat Race Lab

Procedure:

Step 1: Gather all materials and set up experiment.

Materials:
  • Robotic Bug
  • Cardboard box
  • Checkerboard grid paper
  • Video recorder
Tape all checkerboard grids to the bottom of the cardboard box. Set the bug inside the box in any position and turn it on. Take a video of the bug moving

Step 2: Upload the video to Tracker and split it into enough frames for your data.

Step 3: Gather data from each frame. Find the horizontal and vertical position and record them.

Step 4: Find the distance and displacement of the horizontal and vertical positions.

Step 5: Record all data on spreadsheet and write lab report.

Conclusions:

What I Learned:

  •  I learned about finding and using certain formulas for different movements of the bug throughout the lab.
  • I learned how to use Tracker program and how it makes it easier to capture frames of ONE movement to find the data.
  • I learned how to find the data for horizontal and vertical positions. (It's difficult!)
  • I understand distance and displacement better.
Errors in Lab:
  • The positions of bugs could have been a tad off.
  • The formulas could have been off.
  • On Spreadsheet, the formulas messed up for displacement.

Fed-Ex Day Brainstorming

Blogs can be:
  • Persuasive
  • Informative
  • Explaining HOW
  • Make a few little blogs?
  • Make one big blog?
  • Every week? Every few weeks?
  • Subjects on random physics
