DL-Linear Kinematics
Demo - Float in a Jar - The direction of acceleration. Demonstrating positive and negative acceleration and positive and negative velocity
Demo - Free Fall tube. This is a feather in a vacuum demo. I have a steel marble (that I don't put in the tube) and a ping pong ball and a feather.
Lab - Graphs of motion "Labs" on Canvas. These are pretty cool, they watch a video of motion on YouTube with tracking and then they choose the graph of motion that matches the video. I have one for displacement, velocity, and acceleration.
They are in my Canvas Courses, also the regular Canvas Quizzes version is on the commons
Here is the website with all the content:

Lab - Graphs of Motion ILD. Students use the ILD process to analyze various known motion. I use a motion encoder track because it gives better data than a rangefinder. You can have the students do the predictions on a google sheet.

Lab - Moving Plots for IB Physics. We drop a 0.50 kg mass towing a 1.30 m piece of spark timer tape through a 60Hz spark timer, and derive through various means the acceleration of gravity.
The Help Site is helpful:
Lab - Moving Plots for General Physics. A dynamics cart rolls down an incline, then rolls to rest across a table towing a 2.00 m piece of spark timer tape through a 10Hz spark timer. They make beautiful graphs of the cart speeding up then slowing down.

Lab - Air Rocket. Students determine the launch velocity of Low, Medium, High, and Super thrust washers. Students launch the rocket straight up and time from launch until it hits the ground. I talk about random error (i.e. the 5 trials are intrinsically different).
Arbor just released these new systems - You can control when you launch them, as well as at what pressure. Super cool. I ordered 6 of them, and hope to have them all set up for you!! (My gift to you)
Demo - stuff
