How can I create a physics simulation using VPython?

How can I create a physics simulation using VPython?

To create a physics simulation using VPython, you first need to install the VPython library. You can do this using pip: pip install vpython. After that, you can start coding your simulation in Python.

What are some examples of simulations I can create?

You can create simulations like projectile motion, pendulum motion, or even complex systems like solar systems. Each simulation can visually represent the physics involved.

Can you show me a simple code example for a bouncing ball?

Sure! Here's a simple example:

from vpython import *
ball = sphere(pos=vector(0,5,0), radius=0.5, color=color.red)
v = vector(1,0,0)
while True:
    rate(100)
    ball.pos.y += v.y
    if ball.pos.y <= 0:
        v.y = -v.y

This code creates a red ball that bounces off the ground.

How do I add gravity to my simulation?

You can add gravity by modifying the vertical velocity of the ball. For example, you can decrease the y-component of the velocity by a constant value each frame to simulate gravitational acceleration.
