# Python Physics Simulation

Python Physics Simulation we carry it for accessing you to design, visualize, develop physics simulations and examine physical systems, as Python is considered as an impactful tool due to its vast libraries and versatility. Accompanied by few important concepts for more innovative projects, we offer step-by-step measures to configure a simple physics simulation in Python:

__Fundamental Physics Simulation: 2D Projectile Motion__

Excluding air resistance, we have to design a basic simulation of projectile motion under the gravitational force:

**Step 1: Load the Essential Libraries**

Required libraries are meant to be loaded here.

import numpy as np

import matplotlib.pyplot as plt

from matplotlib.animation import FuncAnimation

**Step 2: Specify the Physics of the Problem**

Equations which maintain the motion are following below:

**Horizontal motion:**x(t)=vx⋅tx(t) = v_x \cdot tx(t)=vx⋅t**Vertical motion:**y(t)=y0+vy⋅t−12gt2y(t) = y_0 + v_y \cdot t – \frac{1}{2} g t^2y(t)=y0+vy⋅t−21gt2

In which,

- Ggg indicates the speed in view of gravity.
- vyv_yvy signifies the initial vertical velocity.
- Initial height is determined by y0y_0y0 and
- vxv_xvx represents the horizontal velocity.

**Step 3: Configure preliminary Conditions**

Initial conditions are required to be determined.

g = 9.81 # Acceleration due to gravity (m/s^2)

v0 = 20 # Initial speed (m/s)

angle = 45 # Launch angle (degrees)

v0x = v0 * np.cos(np.radians(angle)) # Initial horizontal velocity

v0y = v0 * np.sin(np.radians(angle)) # Initial vertical velocity

t_total = 2 * v0y / g # Total time of flight

t = np.linspace(0, t_total, num=500) # Time steps

x = v0x * t # Horizontal position

y = v0y * t – 0.5 * g * t**2 # Vertical position

**Step 4: Build the Plot**

Plot must be configured:

fig, ax = plt.subplots()

ax.set_xlim(0, max(x))

ax.set_ylim(0, max(y) + 1)

line, = ax.plot([], [], ‘b-‘, lw=2)

point, = ax.plot([], [], ‘ro’)

**Step 5: Design the Animation Function**

Then, we have to model the function of animation.

def animate(i):

line.set_data(x[:i], y[:i])

point.set_data(x[i], y[i])

return line, point

animation = FuncAnimation(fig, animate, frames=len(t), interval=20, blit=True)

plt.show()

An animated simulation of a projectile’s path is efficiently designed through executing the above mentioned program.

__Description__
