Hot Hits at The Physics Classroom

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.Momentum and Impusle at The Tutorial

One of the most visited pages at The Physics Classroom this week was the Momentum and Impulse Connection page found in the Momentum and Collisions chapter of The Physics Classroom Tutorial. This Tutorial page helps learners to understand the connection between the impulse an object experiences and the momentum change that results. Using graphics and numerous examples, this Tutorial explains how collisions are characterized by impulses that change the momentum of an object. The concept and mathematics are explained and elaborated upon.

2. Impulse and Force Concept Builder

The Case Studies: Impulse and Force Concept Builder is designed to help students gain comfort with the use of the impulse-momentum change theorem. The main outcomes is an understanding of how to use the theorem to analyze a collision to identify how the variables mass, time and velocity change affect the force experienced by an object. There are two difficulty levels in the Concept Builder - Master and Wizard. 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. Roller Coaster Model at The Physics Interactives

One of this week's hottest simulations was the Roller Coaster Model. This Interactive allows a learner to study the interplay between forces, accelerations, velocities, and kinetic and potential energies for a roller coaster car. The track can be modified by lowering and raising strategic locations and by changing the amount of curvature of loops and hills. The simulation is accompanied by a classroom-ready exercise. It is an HTML5, mobile-friendly Interactive that suits itself as an ideal accompaniment to any classroom, but especially for the 1:1 classroom.
