Forces in Circles Concept Builder: in this interactive exercise, students identify the free-body diagrams for situations involving the motion of objects in circles. Learners are presented with a short verbal description of an object's motion. They toggle through a set of free-body diagrams until they find the one that they thinkg is the matching diagram for the description.
Case Studies in Circular Motion Concept Builder: provides learners with the challenge of comparing the speeds, accelerations, and net forces acting upon two objects when given information about the relative radius, period, mass, and speed. Learners must use circular motion equations to think proportionally about these quantities and their dependence upon other variables within the equations.
You might have wondered why you get that queasy feeling in an elevator as you start up and slow down. The phenomenon is explained by some simple physics. This Interactive allows a learner to explore the physics behind the sensations of weightlessness and weightiness ... and you won't get sick in the process. Chromebook and iPad compatible.
With the Roller Coaster Design Interactive, learners investigate the effect of design parameters upon the safety and thrill of a roller coaster ride. Modify the height and radius of curvature of loops and hills and investigate the effect of such changes upon the rider's experience. Accompanied by an activity sheet; works great on iPads and Chromebooks.
Race a car around an oval race track and demonstrate your knowledge of inertia and centripetal force. You're the driver and you use force buttons to accelerate, decelerate, and turn the car in this turn-based (no pun intended) game. Your objective is to stay on the track and use as few moves as possible This requires a good physics understanding and a commitment to watching your speed on the turns. Great 1:1 physics classroom activity; works on iPads, Chromebooks, and smart phones.
This Interactive from The Physics Classroom simulates the motion of an object in a circle. The velocity and force vectors are shown. The speed, radius and mass can be modified. The Interactive is accompanied by an activity sheet; it is a perfect activity for a 1:1 classroom using iPads or Chromebooks. Works on smart phones as well.
