The coefficient of restitution is a number which
indicates how much kinetic energy (energy of motion)
remains after a collision of two objects. This project
measures the coefficient of restitution and determines
how elastic the object is.

The objective of the project is to build a preprogrammed model that will roll or
drive a certain distance. The student determines the number of revolutions that
the car will make to get to the target and student will enter that prediction into the
model vehicle’s display screen and then observe moving vehicle.
