Momentum & Collision Simulator
Simulate elastic, inelastic, and partially inelastic 1D collisions with energy analysis.
Explore elastic and inelastic collisions.
Pulley Calculator
Calculate mechanical advantage, effort force, and efficiency for fixed, movable, compound, and multiple pulley systems. SVG diagrams show rope paths and force arrows.
Pushes & Motion Lab
Apply pushes and pulls to different objects and observe how force type, strength, and direction change motion. Collect data and discover Newton's laws in action. Grades K-2.
Simple Machines & Mechanical Advantage Lab
Explore six simple machines with mechanical advantage, efficiency, and friction. Calculate effort force, distance ratios, and work for levers, inclined planes, pulleys, and more
