I would suggest going to https://www.physicsforums.com/showthread.php?t=110015 and looking at the equations in the first section, 1D Kinematics. The acceleration here is acceleration due to gravity, so that velocity is decreasing at 9.81 m/s each second as the arrow travels upwards, reaching an...

Try adding v2=v20+2aΔx to your arsenal and attack it again ...

Is this a situation where n is large? The difference between dividing by n and dividing by n-1 would be small for large n.

Cool! Thanks! I knew there were things I wasn't thinking of ... the reason I thought of potential energy due to deformation was because of a documentary I watched on the Windscale reactor fire, specifically the part where Wigner energy accumulated in the graphite. Very different materials and...

There is a gummy bear stuck to the ceiling where I work. When it hit the ceiling, some of its kinetic energy would be transformed into thermal energy and some into sound. I'm wondering if some is also stored as potential energy in deforming the gummy bear slightly. Also, are there any other...

I worked with an IR spectroscopy group 12 years ago and the cell windows were NaCl and CaF2. We ran spectra with both because IR absorption patterns were different for the two salts. The windows are hard to clean. The NaCl especially tends to absorb water and requires a special polishing kit...
