Ball-In-Gravity-Trailing

Status

What you need before starting

• Python3
• Matplotlib
• Numpy
• Virtual Environment(recommended)

Supposition

• No air resistance

  This program had not been developed to consider the air resistance.
  

• No ground

   This program had not been developed to consider the Ground.
   The ball will keep going through the own way, both not stoping or bouncing on the ground.
   There is no GROUND to give any force to the ball.
  

How to run

1. clone the repository into your desktop.
2. make a python vertual environment.
3. get into the vertualenv
4. import ball_physics.py in the code where you will use ball_physics function.
5. use the function such as "draw(args)"

• The availiable function list is below.

How to Import API

• Use Below Code

 import ball_physics as bp

Availiable Function

draw(args)

you can draw the trail of the ball on 3D Axes Graph with draw() function.

• args should be passed to draw() as tuple
• example below

  args = (10, 10, 10, 5, 5, 80, 9.8)
  draw(args)

args[0] : initial position of X
args[1] : initial position of Y
args[2] : initial position of Z
args[3] : initial velocity of X
args[4] : initial velocity of Y
args[5] : initial velocity of Z
args[6] : acceleration of gravity

where(args)

you can let your computer calculate the position and velocity of the ball at (n) second after thrown.

• args should be passed to draw() as tuple
• example below

  args = (10, 10, 10, 5, 5, 80, 9.8, 20)
  where(args)

args[0] : initial position of X
args[1] : initial position of Y
args[2] : initial position of Z
args[3] : initial velocity of X
args[4] : initial velocity of Y
args[5] : initial velocity of Z
args[6] : acceleration of gravity
args[7] : time that you want to know position and velocity after the ball have been thrown

Example

draw 5 5 5 10 15 80 9.8

init X: 5, init Y: 5, init Z: 5
int VX: 10, init VY: 15, initVZ:80
acceleration of gravity: 9.8

where 5 5 5 10 15 80 9.8 10

init X: 5, init Y: 5, init Z: 5
int VX: 10, init VY: 15, initVZ:80
acceleration of gravity: 9.8
time after a ball has been thrown: 10.
