One of the many exciting features of PASCO Capstone software is the ability to analyze high speed video. In this particular activity projectile motion is explored with the help of a PASCAR Dynamics System and a Ballistic Cart Accessory.
In this video, a PASCO cart travels along a dynamics track at constant speed. Attached to the cart is the Ballistic Cart Accessory (ME-9486) that fires a vertical projectile it later catches down the track. With the video analysis tools in Capstone, students can track the parabolic trajectory, and analyze the x and y components of motion independently.
This video file was recorded at 210 frames per second. Capstone allows you to analyze high-speed video without the need to place a data point on every single frame. Set a number of frames to skip to give you the time resolution you need. For convenience, the ballistic cart video here is set to skip every 7th frame.

PASCO Capstone features a magnifying tool for more accurate placement of data points. The magnifier hides previously placed data near where you are placing your next object position. This greatly increases your measurement accuracy.
