Plt.plot(x,y) #plot each dataset: columns of x and columns of y Timemat = tmax*np.linspace(0,1,100) #create time vectors for each angle Theta = np.arange(25,65,5)/180.0*np.pi #convert to radians, watch out for modulo division G = 9.81 #improved g to standard precision, set it to positive So here's what I'd do: import numpy as np Unless you set the y axis to point downwards, but the word 'projectile' makes me think this is not the case. This assumes that g is positive, which is again wrong in your code. Lastly, you need to use the same plotting time vector in both terms of y, since that's the solution to your mechanics problem: y(t) = v_*t - g/2*t^2

This is not what you need: you need to compute the maximum time t for every angle (which you did in t), then for each angle create a time vector from 0 to t for plotting!

Thirdly, your current code sets t1 to have a single time point for every angle. You have to convert your angles to radians before passing them to the trigonometric functions. Secondly, your angles are in degrees, but math functions by default expect radians. P = # Don't fall through the floorįirstly, less of a mistake, but matplotlib.pylab is supposedly used to access matplotlib.pyplot and numpy together (for a more matlab-like experience), I think it's more suggested to use matplotlib.pyplot as plt in scripts (see also this Q&A). X = ((v*k)*np.cos(i)) # get positions at every point in time T = np.linspace(0, 5, num=100) # Set time as 'continous' parameter.įor i in theta: # Calculate trajectory for every angle #increment theta 25 to 60 then find t, x, y One more thing: Angles can't just be written as 60, 45, etc, python needs something else in order to work, so you need to write them in numerical terms, (0,90) = (0,pi/2). So time is continuous parameter! You don't need the time of flight. Initial is important! That's the time when we start our experiment. Initial velocity and angle, right? The question is: find the position of the particle after some time given that initial velocity is v=something and theta=something. What do you need to know in order to get the trajectory of a particle? You know this already, but lets take a second and discuss something.

Starting today, BlackBerry 10 users can download the free app from BlackBerry World while the app will be released for Android and Windows Phone in early November.First of all g is positive! After fixing that, let's see some equations: However, when looking for an alternative in the current stores I haven’t been able to find anything nearly as complete as what I wrote in 2004. For instance the new version of the app dynamically performs all calculations in real time, while on my TI-83+ it used to take three seconds of computation time to solve for each variable. Granted the new version of the Projectile Physics calculator is much improved over what I was able to hack together years ago. Nine years later I have decided to revisit the topic and release the app for the smartphone owning public. In addition to all of the games, I also wrote an app that would do my physics homework for me by solving projectile motion problems. The majority of the applications that I wrote were silly little text based adventure games with the occasional ASCII graphics, however there was one program that had a more serious twist to it.

Back then my target was not smartphones and tablets, but rather my TI-83+ calculator. I didn’t buy my first BlackBerry until January 2009, but the truth is that I actually started writing mobile apps way back in 2004.

These factors are solved for in real time in order to help you get back the factors of the equation quicker. The app solves for both the vertical and horizontal components of the distance traveled, the constant acceleration, the initial and final velocity, as well as the time. This app is a projectile physics calculator designed to solve for all of the components of a typical projectile motion problem. Additionally iOS and Android users are now given the option to remove all advertising from the calculator with an in-app purchase.

After this update the app now uses the official ISO value for acceleration due to gravity. The Projectile Physics app has been updated for iOS, Android, BlackBerry, and Windows Phone.
