https://www.oercommons.org/courses/direct-measurement-video-of-a-toy-car-accelerating
This is a short activity intended to allow students to practice kinematics using a video of a familiar object: a spring-powered toy car. Students measure displacement and elapsed time from the video and use these measurements to calculate average speed. Observing that the car has an initial speed of zero, students can find the final speed and acceleration. Students will use a QuickTime video recorded at 240 frames per second, making measurements directly from the video using a ruler and a frame-counter overlaid on the video.

Screen shot from a video of person jumping on a trampoline (Quicktime Video 7.7MB Jul9 12) This clip shows a person jumping on a trampoline. When studying conservation of energy, a common example is a ball being tossed into the air. This is a real life example of a girl jumping on a trampoline that we can use to find her velocity as she leaves trampoline. Using the handout provided students will be able to determine her velocity when she leaves the trampoline based on the fact that they can calculate her gravitational potential energy at two different locations. To enable students with there calculations there is a ruler included in the video.Beth MarcureTechnologyEducation2016-09-15T12:22:35.287366Course Related MaterialsDirect Measurement Video of a Cart Rolling Down a Ramp
