Download the Quicktime file: Video of roller coaster 2 (Quicktime Video 11.4MB Jul23 12) here.

Download the Quicktime file: Video of roller coaster 3 (Quicktime Video 5.8MB Jul23 12) here.


Sample question: What is the speed of the roller coaster?

July 4th Cannon

This clip shows a fire works bomb expelled from a cannon. The cannon is aimed upward, but the camera is turned so upwards is to the left of the screen. The initial explosion that expels the bomb from the tube is visible as a puff of smoke before the bomb is expelled.

Download the QuickTime file: July 4th cannon (Quicktime Video 1.9MB Nov12 12)

Sample question: Determine the speed of the bomb after it exits the launch tube. Based on this launch speed, predict the maximum height of the bomb (assuming it does not explode first).


Toy Car Accelerates

This video shows a toy car accelerating along a table top.

Download the QuickTime file: Direct Measurement Video of Toy Car Accelerating (Quicktime Video 5MB Feb20 13)

Sample question: Determine the acceleration of the car.
