QUIZ on energy and momentum TODAY!
After the quiz, you will work independently to learn about torque. Watch the following demonstration. Think about why my daughter appears stronger than me! (I was actually pushing pretty hard!)
There are two additional videos to watch:
Then, you'll work on some simple torque problems.
Homework: Finish page 1 of the Torque Packet. Watch the video if you need help with the last problem.

Daily Check-in #7: Static Equilibrium - component of force method
Today, we'll apply the concepts of torque and static equilibrium to find the mass of a meterstick. If you still need help here, review the following video.
Lab Safety: Be careful when handling metersticks that you do not swing into someone else. Make sure that you handle masses with care and do not drop off the table as they could hurt you if they fall on you. Always follow your teacher's directions to use the equipment exactly as outlined.
Handout: Torque Meterstick Lab
Homework: If you have not already, finish page 1 of the Torque Packet. Watch the video if you need help with the last problem.
Finally, watch the following video on using the line of action method to solve Static Equilibrium Problems. Also, read the following webpage on Vector Multiplication. Remember that to calculate torque, we use a cross product. Review the right hand rule.
In case you miss class, you can do the above lab by using some materials you have at home:
a ruler (at least 30cm) or meterstick or a long uniform stick that you can measure or put evenly spaced markings on. (Whatever you use should be as inflexible as possible, a metal or flexible ruler will probably not work.)
something thin that you can balance the ruler on (I used a round pencil taped to my desk, but you could perhaps even use your finger).
some coins or washers of known mass (the heavier your ruler, the heavier/more things you'll need) - you'll need probably 8 of the same type.
some tape to secure the coins or washers to the ruler.
Simulation Alternative: PhET Balancing Act - Part 1 can be done using this simulation if you do not have the materials. You'll have to partner with someone in your lab group for part 2 if you don't have physical materials.

Today, we'll try the Hard Torque Problems for practice with static equilibrium. For the first three problems, try using the component of force method. For problem 4, check the video below to review line of action. We will continue working on this worksheet next hour as well.
Homework: Consider finishing the first 3 Hard Torque Problems. Also, make sure that you've watched the "line of action" video by next class.
