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.Coulomb's Law at The Tutorial
One of our most visited Tutorial pages was the page on Coulomb's Law. The page presents Coulomb's law of electrostatic force and illustrates its use in both proportional reasoning and problem-solving exercises. The page provides numerous example problems that range in difficulty from the easy 1-step problems to the challenging multi-step problems that incorporate Coulomb's law with vector principles and Newton's laws. The page ends with a Check Your Understanding section that helps students to self-assess their skill level.
2. Work Concept Builder
The Work Concept Builder is a tool that challenges learners to use an understanding of work and its relationship to energy to analyze numerous situations involving positive and negative work in order to identify the manner in which energy is changing and the forms of energy that are involved. There are 14 different situations to analyze and three different activities, each with its own emphasis. In Activity 1, learners identify whether a situation involves positive work, negative work, or zero work. In Activity 2, learners identify which force is doing work and whether the work contributes to a gain or loss in energy. In Activity 3, learners describe the forms or storage modes of energy that are involved in the situation. The built-in score-keeping makes this Concept Builder a perfect candidate for a classroom activity.
3. Simple Wave Simulator at The Physics Interactives
This week's top Interactive was the Simple Wave Simulator Interactive. This Interactive is part of our Waves and Sound collection. The Interactive allows learners to explore wave mathematics and concepts. The simulator depicts a traveling wave on a rope or a sound wave moving through a column of air. Users can alter the frequency, speed and amplitude of the wave and see immediate changes in the simulation. The distinction between particle motion and wave motion is immediately obvious as learners watch the disturbance move and three "tagged" particles vibrate about a fixed position. The Interactive works well on tablets such as the iPad, on Chromebooks, and on mobile devices.
