1 Answer
the equipment you have to use is a force sensor, multiple carts, multiple masses, multiple springs, a track and some clamps. by putting the cart in motion and observing the oscillation we can see the reduction in amplitude over time and use that to model the decaying amplitude. that model will allow us to evaluate b for the oscillation. our guided question is: is the damping coefficient of a spring-cart system independent of mass?
