Phet free online physics8/19/2023 The sizes of the symbols in the equation change to match the circuit diagram. Adjust the voltage and resistance, and see the current change according to Ohm's law. See how the equation form of Ohm's law relates to a simple circuit. Control energy production in a nuclear reactor! (Previously part of the Nuclear Physics simulation - now there are separate Alpha Decay and Nuclear Fission sims.)ĭetails and get access to Nuclear Fission Start a chain reaction, or introduce non-radioactive isotopes to prevent one. View a Free Body Diagram of all the forces (including gravitational and normal forces).ĭetails and get access to Forces and Motion Charts show the forces, position, velocity, and acceleration vs. Create an applied force and see the resulting friction force and total force acting on the cabinet. Can you identify all the mystery objects?Įxplore the forces at work when you try to push a filing cabinet. Can you discover the relationship? Use the scale to measure the mass of an object, then hold the object under water to measure its volume. Why do objects like wood float in water? Does it depend on size? Create a custom object to explore the effects of mass and volume on density. Play with prisms of different shapes and make rainbows. See how changing from air to water to glass changes the bending angle. See how random decay times relate to the half life.Įxplore bending of light between two media with different indices of refraction. Watch alpha particles escape from a polonium nucleus, causing radioactive alpha decay. Here are some highlights: Online Activity Labs: There are 106 simulations in the PhET Physics Collection. The PhET project is hard at work increasing the accessibility of their simulations, and a number of PhET simulations have accessibility features. They are written in Java and Flash, and can be run using a standard web browser as long as Flash and Java are installed. PhET offers tips for integrating these simulations into your class.Īll PhET simulations are available for free from the PhET website. PhET simulations are very flexible tools that can be used in many ways. Unlike some educational software, these simulations are free, easily translated into multiple languages, and available either online or offline. Going beyond traditional educational resources, PhET simulations offer an intuitive, game-like environment where students can learn through scientist-like exploration, where dynamic visual representations make the invisible visible, and where science ideas are connected to real-world phenomena. PhET Lab experiments represent real interactive, and research-based simulations of physical phenomena from the PhET™ project at the University of Colorado.įor teachers and students around the world, the PhET project provides interactive simulations that are based on extensive education research and support more effective science education. The National Science Digital Library (NSDL).The King's Centre for Visualization in Science.Open Text BC database of OER Labs in Physics and Astronomy.See related teacher-created activity (directly below), developed for use in middle school classrooms with "Wave On a String". Finally, students can view the string's vibration with a fixed end, a loose end, or no end. Students can set amplitude, frequency, damping, and string tension, then observe the results. Or, choose "Oscillator" and traveling or standing waves will be auto-generated. As the sim opens, you can "wiggle" a string to set up a manual pulse or make waves. This PhET favorite has been converted to HTML5 - all ready for mobile devices and tablets.
