Tracker in Teaching Physics
Tracker is an amazing program for physics. It is designed to analyze motion and do modeling from from video clips. It can be used in a bunch of topics in mechanics and the best thing about this program is – its free.
One of the things you can use tracker is in teaching projectiles. Students can easily see how an object behaves as it moves through the air in the x and y component.
1. Using a camera, (or a phone cam) ask them to record the motion of the ball tossed on air, like this:
2. Load the video on Tracker, create a point mass (the object that we need to investigate), track its movement either manually (by shift + click each frame) or autotrack it.
3. Let them investigate the data at the right side of the panel, ask them to look at the x and y velocity of the ball.
4. The students can then discover that an object thrown in the air experiences different motion in the x and y component.
With this program, you can also do authentic assessments by letting them find if a video is faked or not. Here are some things that you can use in your class or have your student try for themselves.

and a lot of other stuff that you can get from movies (even you tube vids like Dude Perfect) to analyze it with the program. This could be another way ( better and a lot cooler) to test students (which are digital natives by the way) aside from conventional quiz that we give.
