Topics Periodic Motion Hooke's Law Conservation of Energy Newton's Laws Measurement Vectors Description Hang masses from springs and adjust the spring constant and damping. Transport the lab to different planets, or slow down time. Observe the forces and energy in the system in real-time, and measure the period using the stopwatch. Sample Learning Goals Determine the factors which affect the period of oscillation Find the value of g on Planet X Design an experiment to determine the mass of an unknown object Describe the relationship between the velocity and acceleration vectors, and their relationship to motion, at various points in the oscillation Explain how the free-body diagram of the mass changes throughout its oscillation Explain the Conservation of Mechanical Energy using kinetic, elastic potential, gravitational potential, and thermal energy
Click to Run Topics Snell's Law Refraction Reflection Optics Prisms Lenses Light Description Explore bending of light between two media with different indices of refraction. See how changing from air to water to glass changes the bending angle. Play with prisms of different shapes and make rainbows.
Topics Vectors Vector Components Vector Addition Equations Description Explore vectors in 1D or 2D, and discover how vectors add together. Specify vectors in Cartesian or polar coordinates, and see the magnitude, angle, and components of each vector. Experiment with vector equations and compare vector sums and differences. Sample Learning Goals Describe a vector in your own words Explain a method to add vectors Compare and contrast the component styles Decompose a vector into components Describe what happens to a vector when it is multiplied by a scalar Arrange vectors graphically to represent vector addition or subtraction
Topics Ohm's Law Circuits Current Resistance Voltage Description See how the equation form of Ohm's law relates to a simple circuit. Adjust the voltage and resistance, and see the current change according to Ohm's law. Sample Learning Goals Predict how current will change when resistance of the circuit is fixed and voltage is varied. Predict how current will change when voltage of the circuit is fixed and resistance is varied.
In a world where attention is currency, and digital communities are shaping our habits, one platform is reimagining how students learn, connect, and even earn: Unitut . If you haven’t heard about it yet, it’s time to pay attention—because Unitut isn’t just another social app. It’s a movement that blends education, technology, and financial opportunity in a way the world has never seen before. π What Is Unitut? At its core, Unitut is a free social network designed for students, tutors, and lifelong learners . Think of it as Facebook meets a study group—with the added bonus of getting paid for your knowledge. Users can create profiles, post questions, share academic content, and collaborate across subjects and grade levels. But here’s the twist: Every time you engage—whether you’re answering questions, uploading study material, or helping another learner—you earn points . And those points? They can be withdrawn as real money . That’s right: you’re getting paid to be smart and ...
