Testing Newton

Physics B and F began a series of lab investigations to verify Newton's 2^nd and 3^rd Laws of Motion. N-3 was the subject of today's work and it was pretty clear pretty quick that the forces produced with two force sensors pulled on each other were equal and opposite. The graphs of force vs. time for each sensor was a lovely mirror image of its partner. Tomorrow, N-2 will be checked using a force sensor and accelerometer.

Honors Physics reviewed their N-2 problems before starting work on N-3. Since my voice is limping badly, students did the introductory work themselves and I'll take up the load tomorrow.

Physical Science went over their exam preparation homework, before tossing out remaining questions in preparation for the exam. Starting Tuesday, we'll be knee deep in forces!
