![]() ![]() The Projectile Motion Calculator works by taking in the inputs and applying different formulas to it, which allows the calculator to derive the horizontal distance traveled, the maximum height of the projectile, and the time taken for the projectile to reach its destination. It can solve for the initial velocity u, final velocity v, displacement s, acceleration a, and time t. How Does a Projectile Motion Calculator Work? The Uniformly Accelerated Motion calculator or (kinematic equations calculator) solves motion calculations involving constant acceleration in one dimension, a straight line. This quickly displays the results and plots a graph for the projectile’s motion. Step 3įinally, after adding both the input values in the Projectile Motion Calculator, we click the “Submit” button. Step 2Īfter entering the projectile’s initial velocity, we add the angle at which the object is thrown in the Projectile Motion Calculator. ![]() The detailed instructions on using the Projectile Motion Calculator are given below: Step 1įirst, we enter the projectile’s initial velocity into the Projectile Motion Calculator. To use the Projectile Motion Calculator, you input the required values in the calculator and click the “Submit” button. How To Use a Projectile Motion Calculator? ![]() The Projectile Motion Calculator requires two inputs the initial velocity of the projectile and the degree at which the projectile is thrown.Īfter inputting the values in the Projectile Motion Calculator, the calculator finds the projectile’s motion. The Projectile Motion Calculator is a powerful tool used by physicists that helps them quickly find and graph the results of a moving projectile.Ī Projectile Motion Calculator is an online calculator that finds the motion of a projectile given its velocity and angle. The online Projectile Motion Calculator is a calculator that calculates the time and distance an object moves when thrown. By multiplying a row vector and a column vector, array broadcasting ensures that the resulting matrix behaves the way we want it (i.e.Projectile Motion Calculator + Online Solver With Free Steps I also used and to turn 1d numpy arrays to 2d row and column vectors, respectively. I made use of the fact that plt.plot will plot the columns of two matrix inputs versus each other, so no loop over angles is necessary. 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. First of all g is positive! After fixing that, let's see some equations: ![]()
