Study of such motion is called ballistics. A projectile, that is launched into the air near the surface of the Earth’s and moves along a curved path, or in other words a parabolic path, under the action of gravity, assuming the air resistance is negligible. Projectile motion is the motion experienced by an object in the air only under the influence of gravity.

Projectiles can roughly be classified into three kinds:Ī projectile which is left to free fall from a considerable heightĪ projectile which is launched directly upwardsĪ projectile upwards at an angle towards the horizontal We can define a projectile as an object which is projected into the air with only downward gravitational force influencing it and continues its motion by the virtue of its own inertia. An object which is in motion in the air with no other force but gravity influencing it is a projectile. When we throw an object up, due to the force of gravity it eventually comes down. The object which is launched into the air is called projectile, and this kind of motion is called projectile motion. Due to the influence of gravity, that object takes a curve path forward towards the ground before it eventually stops after touching the ground. But since the object is also under the influence of gravity, it also dips down in the ground. Also, if you launch an object up into the air, it travels into the air due to its inertia of motion. Gravity influences any object suspended in the air to fall downwards, as in the case of fruits from trees. By multiplying a row vector and a column vector, array broadcasting ensures that the resulting matrix behaves the way we want it (i.e.We all know from Newton’s Universal Laws of Gravity that any object on Earth is constantly influenced by gravity and pulled towards the center of the gravitational field, that is the center of the Earth. 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:
