physics-simulator

how-to

• click a particle to select it
• drag an object to change its position
• shift-drag an object to change its initial velocity
• click the canvas to remove the current particle selection
• press the gear icon with a particle (the canvas) selected to edit the particle properties (background fields)
  • the background field editor can use three parameters: $x$, $y$, $v_x$* (v_x), $v_y$* (v_y), and $t$ in the field calculation
  • $x$ and $y$ are the positions of the particle
  • $v_x$ and $v_y$ are the velocities of the particle
  • $t$ is the time since simulation has begun
• press the play/stop button to play/stop the simulation
• levels can be loaded and saved after being created using the buttons in the header of the simulator

^{(*it is technically unphysical for a gravitational or electric field to be velocity-dependent, but it is a neat feature)}
