Fresh Ideas for Your Relative Speed Discussions

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 direction and in opposite directions.

In this demonstration Joel Bryan of Ball State University explores Relative Velocity (Speed) with cars; Moving Opposite Directions (Toward Each Other); Moving Opposite Directions (Away From Each Other); Moving Same Direction (Faster Car in Back); and Moving Same Direction (Faster Car in Front). Watch Professor Joel Bryan explore Relative Velocity with cars here:

Constant Velocity Car
This simple but powerful toy provides a visible source of uniform speed. Students can easily quantify and graph their results, starting them on the road to a conceptual understanding of motion.

Car and Ramp 2.0 Lab
Experiment with distance, time, velocity and acceleration, Newton's laws and simple machines. The 120cm ramp attaches to the Workshop Stand at angles up to 65°.

Pull-back Car
This companion to our popular Constant Velocity Car demonstrates nearly constant acceleration. Simply pull back on the spring-loaded, die-cast roadster, then release. Use a motion sensor or tape timer to measure the acceleration.

Fan Cart
Even Sir Issac Newton would have been a fan of the Fan Cart! The Fan Cart is perfect for exploring Newton's laws of motion, inertia, acceleration, and action-reaction.
