This is a demonstration of Newton's First Law using a cart on a track, showing that objects at rest remain at rest and objects in motion remain in motion with constant velocity unless acted upon by a net force. The video discusses how a car moving down a straight road at constant velocity has no net force acting on it.

This demonstration was created at Utah State University by Professor Boyd F. Edwards, assisted by James Coburn (demonstration specialist), David Evans (videography), and Rebecca Whitney (closed captions), with support from Jan Sojka, Physics Department Head, and Robert Wagner, Executive Vice Provost and Dean of Academic and Instructional Services.
