Energy Skate Park: Basics 1.1.35 - PhET Interactive Simulations
Explore the interactive simulation of Energy Skate Park to learn about energy conservation and observe kinetic, potential, and thermal energy changes.
Circuit Construction Kit: DC - PhET Interactive Simulations
Experiment with an electronics kit! Build circuits with batteries, resistors, ideal and non-Ohmic light bulbs, fuses, and switches. Determine if everyday objects are conductors or insulators, and take measurements with an ammeter and voltmeter. View the circuit as a schematic diagram, or switch to a lifelike view.
