Physics 30 Energy Exam

We have another Physics 30 exam right around the corner!

The Work, Power, and Energy exam will be Friday, May 25.


We will write a Practice Exam in class on Thursday, May  24. The Practice Exam answers will be found HERE.

The Gravitational Potential Energy Problems assignment answers are found HERE.


The answers for the multiple choice section of the review are found HERE.
The other part of the review is the Work, Power, and Energy Practice Assignment. You can find those answers HERE.

• To get a Bonus mark you need to complete both parts and get it signed.

Here is an applet you can experiment with to aide your understanding of Energy. CLICK HERE The applet has a skateboarder and you can create the track/halfpipe that s/he travels in. To see the energies you can turn on a Pie Chart and/or a Bar Graph. Notice that at the top of the ramp all of the energy is Potential Energy. At the lowest point all of the energy is kinetic. What does this same about the speed at each point?

Good luck and have fun!

Physics 20 Optics Exam

Our Optics Exam is set for Friday, May 18. The exam covers:

• human eye
• eye defects
• vision correction
• lens diagrams
• Thin lens equation
• Power of a Lens
• Applications of Optics - including telescopes
• Colour Theory and Polarization

Good luck!

Please, complete the review. If you complete it showing all of your work and get it signed by a parent or guardian, you will receive a bonus mark on the exam.
The review answers may be found here: PAGE 1 PAGE 2

Math Foundations 20 Project Submission

Here is the final submission before your project is due. Please, fill out the form and submit.

Math Foundations 20 Angles and Polygons

Our exam is on Friday, May 11.

The review assignment that you can complete for bonus is p. 106 #2-4, 5b, 7, 9-11

Physics 30 Forces Exam

Here are a couple of applets that may help with the studying.

Law of Universal Gravitation: HERE Try changing the distance between the objects to see what it does to the Force. Try changing the mass too!

Forces including the frictional forces: HERE In this applet, keep increasing the applied force until the object begins to move. You can then decrease the applied force and it will continue to move. Why is that? What is the relationship between kinetic and static friction? If you increase the object's mass, what does that do to the necessary applied force?


The exam will be on Thursday, May 10. The topics covered will begin at Newton's Laws. The other topics covered are Gravitation, Mass/Weight, Friction, Free Fall, and Momentum. You can find the review answers here: PAGE 1 PAGE 2

On Wednesday, May 9 we will write a Practice Exam in class to assess if you are ready for the exam. Here are the answers: PRAC EXAM

Please, if you are having any trouble at all, see me immediately! I want to be able to help you prepare for the exam, but I am away from school on Monday and Tuesday, so please see me ASAP.

Good luck!
