  • Fresh Ideas for Your Relative Speed Discussions

    Posted on September 1, 2011 by Dr. Joel Bryan

    Whether we realize it or not, all velocity/speed measurements are made relative to some other object. When your car's speedometer reads 55 mph, the assumption is that the change in position of the car compared to the stationary ground is 55 miles every hour. However, not all velocity/speed measurements are made relative to a stationary object. The Constant Velocity cars allow students to experimentally investigate relative speeds as the cars with different speeds move in the same and in opposite directions.
