An experiment to investigate simple harmonic motion consists of a mass oscillating at the end of a vertical spring.
The mass oscillates vertically above a motion sensor that measures the speed of the mass. Test 1 is carried out with a 1.0 kg mass and spring of spring constant . Test 2 is a repeat of the experiment with a 4.0 kg mass and spring of spring constant .
The variation with time of the vertical speed of the masses, for one cycle of the oscillation, is shown for each test.
In test 2, the maximum elastic potential energy Ep stored in the spring is 44 J.
When t = 0 the value of Ep for test 2 is zero.
Sketch, on the axes, the variation with time of Ep for test 2.
