Thanks for bearing with me, I don't know why this is so hard for me to get my head around. I think it is starting to sink in.
c = Acceleration = the numerical value of Distance Fallen in first second
So, we're really talking about acceleration in that first second.
At one second Distance...
The math you posted makes sense if we are really talking about "Velocity in the first second" m/s^2
I think the mess up in my mind is the description of "Distance Fallen in first second"
Should the speaker have said "Velocity in the first second"?
Thanks Bandersnatch,
Distance Fallen in first second = acceleration was the key to making everything work.
Displacement in meters = m/s2 * s2
Velocity in meters per second = 2 * m/s2 * s - m/s2 * s
Acceleration in meters per second squared = 2 * m/s2
Gravity in meters per second squared = 2 *...
Please ignore strikeout (not sure why post is doing that)
I just watched a video from Caltech (Video link at bottom of post)
It says:
Displacement = Distance Fallen in first second of time in [m] * Time2
so Time2 has no si unit as it is just a ratio right?
Instant or Average Velocity = 2 *...
Thanks, CWatters and SteamKing, you 2 were a big help!
I *think* I have it under control now.
I *believe*:
S = (BallSpin * BallRadius) / BallVelocity
R = BallRadius.
And I think the equation was missing all the closing brackets on the end.
I have been at this for days. :)
I seem to be getting...
Hi,
In this article there are some symbols that I do not know what they are can you help me identify them?
http://www.ijimt.org/papers/419-D0260.pdf
Page 347 at the top the equation for CL what does the 'R' stand for? And while we are looking at the same equation. |w| is the magnitude of ball...
Ok, maybe as I go through that document I can ask for some help if that is ok?
In figure 1 of the pdf document. It talks about unit vector l, v, and v x l. Then spin rates around these axis.
I am unsure what these axis are. The arrows in figure 1 do not make sense to me.
They look like like...
Thanks for the reply MarcusAqgrippa. I ended up stumbling upon this article that explains the effect in 3D space. http://www.crm.cat/en/publications/publications/2013/pr1154.pdf I do not totally understand it though. My implementation of the 2D effect can be found here...
I am working on simulating the magnus effect of lift on a spinning ball. Right now spinning on the z axis I can calculate the force effect it has on the x and y coordinates.
If I am to add spin on the x do I do the exact same calculations effecting the y and z coords and just add them to the z...
