Physics app allows fun fieldwork

Vernier Software & Technology’s new Video Physics app allows educators to take a video of an object in motion, mark its position frame by frame, and set up the scale using a known distance. Examples of its use in the field include: measuring the velocity of a free throw shot, a child's swing, a roller-coaster, or a car. Video Physics then draws trajectory, position, and velocity graphs for the object.

Vernier is giving away iPod touches and iTunes gift certificates as awards for the most creative video analysis clips using Video Physics on behalf of their school.
