DOWNLOAD FOR BEST EFFECT! Two blocks, connected by springs. You can change the length and stiffness of each spring, the mass of the blocks, and the damping force (friction). Click near a block to drag it around. All the equations of motion for this project are completely realistic (they would work like this in real life). Press reset to set the model in equilibrium. Thanks for watching and please leave a comment! Updates: -The spring is green if is it longer than resting length, and red if it is shorter than its resting length. -Blocks can actually go far off the edge, and its connecting spring does the same -Special and easy dragging system
