You notice that in the first part of the lab, with the mass moving up and down that the velocity is continuously changing. May you use the kinematic equations to determine the position or any other parameters (e.g. velocity or acceleration). Why or why not? Explain your answer for full credit. 2. How well does the spring obey Hookes' law in the simulation? Explain. 3. This question refers to part one of the lab (the mass on the spring). How would a graph of the total mechanical energy versus time look if a non-conservative force, such as air resistance, is included?
