SimReal SimReal - VPython - GlowScript - Trinket - Physics - k03 - Particle Particle: A particle is moving according to the following parameteric curve: x(t) = 10cos(3t) y(t) = 5sin(2t) This application is a simulation of the motion of a particle (green color) moving on a given path. Click 'Run' and you will see the particle (green) in the simulation window together with the path (white), the position vector (green), the velocity vector (blue) and the acceleration vector (red).
