kinetic vs. time graph for one period
The graph shows that the mass completed two full motions from the starting point. The harmonic motion for this time period is what caused the parabola to form. As shown in this graph I can see that the kinetic energy started at about 0.4 J at about 0.3 seconds and rose as it went towards the equilibrium point at about 3.1 J at about 0.18 seconds and lowered from 0.21 to 0.38 seconds and dropped from 3.1 J to 0 J.
Total mechanical energy Vs. Time For one Period
This graph looks very similar to the graph above. Their harmonic motion is actually the same but at different heights. The total mechanical energy would be the same harmonic motion because it is just the kinetic energy combined with the potential energy. The total mechanical energy harmonic motion still formed a parabola and had the energy rise and fall at the same slope.
gravitational potential energy vs. time for one period
A few points are missing after the 0 and before the 0.8 seconds. The shape of the graph is not like the others. It doesn't complete a full parabola and it doesn't really have the harmonic motion. The gravitational potential energy must of not stored a lot of energy when the mass was heading towards the highest point. But it was greater when the mass was heading towards its lowest point.
Kinetic vs. time f0r entire m0tion
This graph shows the entire motion of the kinetic energy during the whole lab. The mass had a very good continuous harmonic motion. As you can see at the end a glitch must of happened with tracker or the video stopped before the mass could complete the last harmonic motion. And i also noticed there was a gradual decrease of kinetic energy of the graph which indicated that energy was being converted. The kinetic energy was probably converted to heat in the spring or sound.
