UCM to Projectile: Optimum Launch Angle/Velocity Dependence?

AI Thread Summary
The discussion centers on the optimal launch angle of a projectile exiting uniform circular motion, which is suggested to vary with initial tangential velocity according to a WinPlot simulation. Participants seek clarification on what constitutes "optimal," defined as the angle that maximizes range. The range equation indicates that, without air drag, a 45-degree angle consistently yields maximum range, irrespective of initial velocity. This raises questions about the simulation's accuracy and the conditions under which the optimal angle is determined. The conversation highlights the need for further exploration of the relationship between launch conditions and projectile motion.

I ran a simulation on WinPlot (see attached video) on my computer and was a bit surprised to see that the optimal launch angle of a projectile (with NO air drag) leaving uniform circular motion is dependent on the initial tangential velocity (or at least Winplot thinks it does).

Can someone shed some light on this phenomenon or point me to my error?

What is "optimal?"
 
By "optimal," I mean the angle that produces the maximum range.

As compared to what sort of launch?

As opposed to being launched from ground level from a cannon or something.
The range equation (with no air drag) is ##R=v^2sin(2a)/(2g)##. In that case the maximum range is achieved by using a 45 degree angle of elevation REGARDLESS of the initial velocity.
 
Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...
I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
