Open Source Physics. Computational Resources for Teaching The OSP Collection provides curriculum resources that engage students in physics, computation, and computer modeling.
EJS Modeling Learn more about EJS Tools. Forces in 1 Dimension - Force, Motion, Friction. E13. E25. Name That Motion Interactive. Using the Interactive The Name That Motion Interactive is shown in the iFrame below.
There is a small hot spot in the top-left corner. Clicking/tapping the hot spot opens the Interactive in full-screen mode. Use the Escape key on a keyboard (or comparable method) to exit from full-screen mode. There is a second hot-spot in the lower-right corner of the iFrame. This Interactive will open in a separate browser window on your device. Having troubles viewing the video? Graph That Motion. The Graph That Motion Interactive consists of a collection of 12 challenges.
Each challenge presents learners with an animated motion of a car. After viewing the motion, one must match the motion to the corresponding position-time or velocity-time graph. Feedback is immediate and mulitple attempts to get the matching graph correct are allowed. Launch Interactive This Interactive is self-supporting; there is no suggested exercise. Learners and Instructors may also be interested in viewing the accompanying Notes page. Accelerometer. Created by our friends at Nerd Island Studios, the Accelerometer Interactive allows learners to collect data of velocity as a function of time for their mobile device.
If the device has a built-in accelerometer, the Accelerometer Interactive will be able to plot an acceleration vs. time graph as the device moves. Newtons Laws. Force When forces are unbalanced, objects accelerate.
But what factors affect the amount of acceleration? This Interactive allows learners to investigate a variety of factors that affect the acceleration of a box pushed across a surface, The amount of applied force, the mass, and the friction can be altered. A plot of velocity as a function of time can be used to determine the acceleration. Free-Body Diagrams The Free-Body Diagrams Interactive is a skill-building tool that presents users with 12 physical situations for which they must construct free-body diagrams. Rocket Sledder Created by our friends at Nerd Island Studios, this Interactive illustrates the effect of friction, air resistance, and applied force upon a sledder. Skydiving Created by our friends at Nerd Island Studios, this Interactive allows the learner to explore the motion of an object falling under the influence of air resistance.
Everyone is fascinated by pulleys. Acceleration vs. Constant Velocity. Observe the animation of the three cars below.
Use the animation to answer the three questions. (If necessary, review the definition of acceleration.) Magnets and Electromagnets - Magnetism, Magnetic Field, Electromagnets. Topics Magnetic Field Magnets Electromagnets Description Explore the interactions between a compass and bar magnet.
