Physical Science 20 - May 4

Today students started to learn about refraction.  This is another property of light that describes what happens when light enters another substance.  Students took notes on slides 44-51 in the powerpoint.  We finished those notes today and students then worked on Part A of the refraction practice problems worksheet.  These are worksheets that students picked up today in class. 

Physics 30 - May 4

May the Fourth be with you all!!  Today in physics we derived a couple of equations related to gravitational circular motion and went through a couple of examples that utilized those equations.  These were examples 6 and 7 in your notes covered on slides 19-22. Assignment 4.2 was given at the end of the class.Tomorrow we will be doing Lab 4.2

Physics 30 - May 3

Today in class we talked about the lab that students did yesterday on horizontal projectile motion.  The reports for this lab are due on Wednesday.  There is a set of data in the course notes link under the Unit 4 folder if students were absent yesterday.  We started to look at universal gravitation today and how to some of the intricacies of using the law of universal gravitation.  This was all covered on slides 13-18.  On Monday we will look at gravitation circular motion.

Physical Science 20 - May 3

Today we learned how to find the image mathematically using a set of equations.  We took some notes on the equations and how they work and then went through some examples.  This was covered on slides 32-37 on the powerpoint in the Physics folder of the course notes.  When this was finished, students then worked on Homework 2.6.  We will cover over these tomorrow.

Physical Science 20 - May 2

Today we continued learning how to draw diagrams to find the image in a curved mirror.  Today we looked at convex mirrors.  After this, students had some time to work on Assignment 2.3 which is due tomorrow.  Tomorrow we will learn how to find the image mathematically.

Physics 30 - May 2

Today we did Lab 4.1 on horizontal projectile motion.  The lab report for this report is due on Wednesday.  Tomorrow we will be moving on and learning about gravitational circular motion.  If students were absent today, you can use some sample data that is in the course notes link under the Unit 4 folder.  The file is called Lab 4.1 Sample Data.

Physical Science 20 - April 29

Today we started to learn about curved mirrors and how they work.  Students just learned about some different terminology that we are going to use to describe curved mirrors.  This was all covered on slides 27-31.  
We then started to figure out how to draw ray diagrams for curved mirrors and how to find images in a curved mirror.  This involved drawing three separate light rays and having them reflect off of the mirror.  Students read through the instructions on how to draw the diagrams.  We only learned how to do concave mirrors today.  On Monday we will continue with convex mirrors.  The notes today were on slides 40-41 but students should have a handout called Drawing Ray Diagrams for Curved Mirrors.  The notes are all on this handout.
