Where should I post questions about how to make a DIY Stirling Engine work?

Just how to use the foumulas and what each one does also their names. V = Vo + at X - Xo = volt + .5at2 v2 = vo2 + 2a(X - Xo) X - Xo = .5(Vo + V)t Thanks again Also if I am missing any fourmulas let me know (I just want the formulas that relate to 1d and 2d kinematics)

Can Anyone Help Me Understand Kinematics? I just need to know a little more about 1-d kinematics. Note: I have read the definition and the formulas but I still need help! Thanks for any help! It is all gladly appreciated!

I did some tests on a new tennis ball... It's c.o.r. was about 0.75... Any more help is gladly apprecreated! :biggrin::biggrin::biggrin::biggrin:

What I meant by the three colored parts of this quote, is that... #1. "Height" = The height from the ground to the point of reference on the ball... ((This is basically the position at which the ball will be at the singular point of time given)) -Note: See "#2" for "Time given"- #2...

What if i want to figure for a tennis ball? (Mass = 58 grams, max height of 2nd bounce = ?, height of drop = 10ft) Rest of conditions are same as before... By the way, I need to make a graph of the results.

:confused:What?:confused: I don't understand what i need to do... Edit note: not derected at you "tiny tim"

What is the equation to find the height of a bouncing ball under Earth's gravity (9.8?) if given the time (t) from the start of the drop (10ft) if the ball is either a tennis ball or a ball that reaches 1/2 of the previous max height? (Ignoring air resistance & spin) In addition, the angle of...
