Friday 14th December

Hey folks,

Let's do the test on Monday so I am there. Today work on circuit analysis with the test questions given out yesterday. Here is a link to the test if anyone needed a new copy.

Here and here are some online practice questions and/or you can check out the text book as well for some additional practice.

Have a great day and weekend.

Force Friday Nov 30th

Take a look at these following videos.

1) Identify the type of motion (at rest, constant velocity or accelerated).
2) Draw free body diagrams for the object(s) of interest at various key points in time.
3) Describe the motion using Newton's laws.

If you are unfamiliar with the forces at play, still identify them as a result of the objects motion.

Thermal Physics - Function of a fridge

Here are some resources to help consolidate concepts related to the function of a fridge.

We will have a short quiz on the topic Monday of next week.

Force Friday Nov 2

Hello all,

To review today and remind about the homework.

1) create your table for free body diagrams for all important moments (transitional between types of motion) for a bungee jumper. See this video as reference.  (turn sounds down.....)

Crazy!!!!!! 

The bridge we talked about in class.

2) watch this commercial and talk about the physics of pulling out the table cloth without making a mess..

Have fun!

Inquiry and Confirmation Laboratories

Hello all,

We are going to work on our first formal inquiry/confirmation lab in the grade 11 physics course. Below is a list of resources that will help you in the process as well as list of possible labs to complete.

Grade 11 physics handbook which includes the lab rubric, instruction on each component of the lab report, a guided explanation of the confirmation lab process and an exemplar of the types of appendices that may be used.

Here is a link to an exemplar lab (grade 10) which will help with formatting. Note that the lab is done to grade 10 requirements and does not have the integrated purpose paragraph. Please see exemplar in physics handbook for help with that section.

Equation editing links

Lab choices:

1. Confirm Newton’s 2nd Law by confirming the acceleration of an object is directly proportional to the net force applied on the object.

2. Confirm Newton’s 2nd Law by confirming that the acceleration of an object is inversely proportional to the mass of the object.

3. Investigate friction.

4. Investigate a factor which affects the energy efficiency of a simple machine (you can not choose an incline plane as your machine).  

5. Investigate a factor or factors which affect the power generated by human activity.

6. Investigate a factor which may affect the period of a pendulum.

7. Investigate a factor or factors which affects the specific heat capacity of a substance.

projectile motion practice

Here are some links to try. The old 12 book (P.43 - P.51) is also a good resource for some more challenging problems.

First Newton's Laws Quiz SPH3U

Hello all,

Today we will do a quiz to check where we are with FBDs and Newton's Laws:

First watch: https://www.youtube.com/watch?v=d7iYZPp2zYY

In your lab booklets complete the following: (make sure there is a date, title and clear subtitles to show me what is what)

1.  For both the no seat belt case and the seat belt case:
1. draw as many free body diagrams as necessary to fully identify the types of motion (at rest , constant velocity, speeding up, slowing down)
2. explain an example of each of Newton's laws from the video
2.  Summarise why seat belts save lives.

Lab Booklets and Bridge Build Competition

Hello all,

Our first real task is to assemble our lab booklets then complete the bridge building challenge.  Here are instructions and constraints.

1.  Create a cover page for your lab booklets and include; 
1. name, course code + lab booklet, and draw an image about something that interests you in the realm of physics.  
2. take approx. 30 lined sheets and a back cover and staple your lab booklet together. 
2. Bridge Build Challenge:
1. at your table groups, brainstorm, design and build a bridge with only one newspaper (no other materials allowed). The bridge must comply with the following requirements:
1. span two desks at a distance of 50 cm from each other
2. be capable of attaching a force sensor to the middle underside of the span 
3. not be connected or supported to any surface other than the top surface of the desks
4. competition winner will be the bridge that supports the highest load in newtons divided by the mass of the bridge in kg. (ie an advantage to having a strong/light bridge)
3. complete a lab book entry with the following: (will be marked)
1. date and entry name 
2. design sketches including dimmesions
3. recorded data (mass and load)
4. calculation for competition (mass/load) ** do not forget about units!!!

 Have fun!!
