Week of October 6, 2014

This Week in AP Physics
On Monday we will design an experiment to compare inertial mass with gravitational mass. On Tuesday your lab report on the horizontal range of projectiles is due. Also on Tuesday we’ll analyze multiple situations involving tension force so that you can do homework 2 for Wednesday followed by a quiz as announced for Thursday or Friday. Late in the week we’ll design an experiment to test Newton’s second law, and we’ll also explore friction.

This Week in Physics
On Monday we’ll tie up any loose ends related to vector operations (covered in Unit 2 Podcasts 1-4) so that we can quiz over this topic on Tuesday (or as announced.) For Monday (6th period class) or Wednesday (10th period class) please take notes on Podcast 5 – Introduction to Vector Resolution and Podcast 6 – Vector Resolution Sample Problem. We will review these in class and then do assignment 2 together. As announced please take notes on Podcast 7 – Introduction to Projectile Motion part 1Pocast 8 – Introduction to Projectile Motion part 2, and Podcast 9 – Introduction to Projectile Motion part 3. For the following day please take notes on Podcast 10 – Projectile FormulasPodcast 11 – Projectile Sample Problem part 1, and Podcast 12 – Projectile Sample Problem part 2. Expect a test sometime next week.

This Week in Astronomy
We will continue to explore the motion of the sun as the seasons change, as the time of day changes, and as our latitude changes. We’ll also analyze data of solar radiation throughout the USA to see how well our predictions regarding sun position correlate with the amount of solar radiation received. Expect a test late this week or early next week. The Unit 2 Podcast – The Ecliptic and its Implications will aid your work.

Cool Science of the Week
Real life invisibility cloaks? Using the optics principles from physics, researchers have developed a way to make moving objects seem to disappear. Mischief managed!
