Every Saturday we highlight three resources that have received particularly heavy traffic from website visitors during the past week. This week's winners are …
1.Definition and Mathematics of Work at The Tutorial
A very popular page at The Physics Classroom Tutorial was the page titled Definition and Mathematics of Work. The page lays the foundation for understanding mechanical work and its connection to energy. The page combines informative text written in an everyday style, graphics, widgets, a quick quiz and more.
2. Momentum Concept Builder
The Momentum Concept Builder is designed to help students build an understanding of momentum. The main outcomes are an understanding of the dependence of momentum on mass and velocity and the vector nature of momentum. There are three activities in the Concept Builder - What's Happening With Momentum?, Momentum Ranking Tasks, and Getting Direction on Momentum. Question-specific help is provided for each question. The built-in score-keeping makes this Concept Builder a perfect candidate for a classroom activity.
3. Uniform Circular Motion at The Physics Interactives
One of this week's top Interactive was the Uniform Circular Motion Interactive. This Interactive is part of our Circular and Satellite Motion collection. The Interactive allows learners to explore the concepts and mathematics associated with objects moving in circles at a constant speed. The Interactive has controls for modifying the object mass and speed and the radius of the circle. The acceleration and net force are reported on a digital display. Velocity and acceleration vectors can be toggled on an off. The Interactive is accompanied by an activity sheet that can be used by teachers with their classes. The Interactive works well on tablets such as the iPad, on Chromebooks, and on most mobile devices.
