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.
