Hi, really educational video. I was wondering if and how one can move the coordinates lines frame to frame. For a project I have, it would be useful to pick as the Cartesian lines’ origin a given point and keep it as such throughout the time Tracker is following a point mass.

Hey Brian, great video. Helped me with my physics lab. I have a question? Why does the velocity and acceleration data do not start in the first frame when shown recorded values? Thanks, Mark

Velocity is defined as the difference (change) in position in a time interval. So you need two data points before you can calculate the first velocity point. Similarly for acceleration.

Hi Brian, hope all is well. Quick question for you I’m doing a lab where I throw the ball from one place to another across the room and I’m using tracker. It’s a lab and they want us to estimate the maximum height of the ball traveled above my hand, not the earth. What would be the steps you would have to do to measure this in tracker? How do I find the height of the ball above the hand? It is standing from one side and throwing it in an arcing motion to the other. It’s not in the single position like this video that they want us to measure the height. If you could help me with this I would greatly appreciate it.

When doing the calibration, set the axes' origin to your hand location. The y vs. t data will be a parabola. The max of this curve is the max height above your hand.

wow. I have to try this in class. I put students to film their hobbies and analyze it.
