Mass on a Spring
After running the simulation press the Reset button to activate the sliders. To get the total energy graph to display correctly after changing the initial velocity, hit the Reset button again.
First experiment with the simulation to see what effect changing the initial velocity and the mass has on the motion. Then consider the following four cases, which differ in the settings used in the simulation above:
Case A: Initial velocity = +v; Mass = m
Case B: Initial velocity = -v; Mass = m
Case C: Initial velocity = 0; Mass = m
Case D: Initial velocity = +2v; Mass = m
Predict the results of the questions below, and then use the simulation to verify your predictions.
(a) Rank these cases based on the oscillation amplitude, from largest to smallest (use the notation > or =, for example A>B=D>C).
Answer is not case sensitive.

(b) Rank these cases based on the time (after t=0) the mass first passes through the equilibrium position, from longest time to shortest time (use the notation > or =, for example A>B=D>C).
Answer is not case sensitive.
