Summary
[edit]
| Description |
English: This shell-frame view of a constant "net-acceleration" round-trip jump illustrates a few of the things that the first part of an intro-physics course on basic physics or mechanics & heat might provide insight into. Constant-acceleration round-trips are also interesting when the subject of astrophysical voyaging comes up.
In addition to illustrating certain concepts, this might come in handy for quantitative analysis in the context of various empirical observation exercises. And then there are its prospects for being tiringly repetitious... |

Further notes
[edit]
Assuming that this stick-person is 5'11" or about 1.8 meters tall when standing straight (i.e. just before leaving the ground), what's the depth of the crouch before the jump, the height of the jump after launch, and the acceleration-due-to-gravity assuming that the animation is in real-time.
Note that you can freeze the animation mid-frame by hitting escape on some browsers. This may come in handy if you want to do quantitative work on the movement between after-images.
If you knew the stick-figure's mass to be say 80 kg, one might also be able to track work and energy flows throughout this jump. For example, imagine starting with chemical potential-energy in the stick-figure's leg muscles in the crouch before the jump. What forms does that energy take throughout the process, where does the energy end up, how many Calories (at least) are burned in a single jump, and how much carbon weight was likely exhaled as a result?
If you further knew the mass of the planet on which the stick figure was standing, you might also consider translational momentum in this process. When is the jumper's momentum at its maximum value, what is that maximum value, and what maximum recoil velocity for the planet does that imply during the jump?
