This is just a test using trigonometry in scratch. Watch several pendulums swing. Drag the pendulums from either the root or the ball to move them. Slide DRAW_VELS? to 1 to show the pendulums' scaled velocities. Used old, but good tutorials: https://scratch.mit.edu/projects/1884342/ https://scratch.mit.edu/projects/1584815/ #Pendulums #Trigonometry Changelog: v1.1 After dragging pendulum, vel carries on. v1.0 Pendulum with gravity, can drag balls & roots.
