Demonstration Description: In this experiment you allow a cart to roll down an inclined ramp and run into a spring
that is attached to a force sensor. You will measure the position of the cart and the force
exerted on it by the spring while they are in contact. It is a "real world" experiment,
which means that there are non-conservative forces: friction as the cart rolls up and down
the track, and dissipation (internal friction?) in the spring. The goals of the experiment
To investigate experimentally the work-kinetic energy theorem, how potential energy
in a gravity field converts to kinetic energy which is then converted into the potential
energy of a compressed spring.
To observe and quantify the effect of non-conservative forces and estimate the work
done by these forces at various stages of the cart's motion up and down the ramp.
