Collision Carts
Explore momentum conservation in a two cart system with momentum and energy bar charts, as well as motion and force graphs. Adjust elasticity and collision time or create an "explosion".
Marble Hits a Cart
Visualize what affects one object can transfer momentum to another object. Adjust elasticity to allow objects to bounce, stick, or pass through each other. Analyze momentum and energy.
Stacked Graph Collisions
Study collisions using multiple representations: velocity, momentum and force graphs synchronized with animation. Original by William Calhoun and Brian Frank.
Spring Shot
Launch a cart using a spring and observe how energy is transformed between potential, kinetic, and thermal.
Simple Harmonic Motion
Observe oscillations in a horizontal spring-mass system. Analyze motion, force and energy graphs over time and identify key features of simple harmonic motion.
Mass-Spring in Gravitational Field
Investigate how gravity affects equilibrium and motion in a vertical spring setup.
Damped Driven Oscillator
Explore resonance and damping as you apply periodic forces to an oscillator. Analyze motion and energy vs. time and well as vs. position
