You can download the Vpython from the official site. You need to install both Python and VPython compilers. Now we can look at the VPython but before you start writing any code, you need to install VPython on your computer. Consider, the position of the object at time t to be represented as x(t), after a time dt, the position changes to x(t+dt) which is given as: The velocity results in the change in position of the object. Consider the initial velocity of the object be v(t) and after a time interval of dt, the velocity change to v(t+dt) which is given as: The acceleration results in the change in velocity of the object. You just need to know that when an object falls under the effect of gravity, it experiences an acceleration due to gravity ( g = 9.8 m/s 2). You do not need to know deep physics to understand this simulation. In this post, we are going to simulate a ball which falls under the effect of gravity and bounces off after striking the floor.

You can use all the commands and codes of Python language in VPython also. You can assign different attributes to these objects like size, mass, color, position, velocity, acceleration etc. In VPython, you can create various objects like sphere, box, cone, cylinder etc. Visual Python (VPython) is a module in Python programming language which provides a platform to make 3D models and simulations.
