Material Detail

Content quality - The simulation helps learners visualize the position vector and the velocity vector in a uniform circular motion. The site explains that the object accelerates due to the change in the direction of its velocity and indicates that this acceleration is toward the center. Newton's Second Law is also used to justify that there is an unbalanced force and that it must also point toward the center of the circle. The text refers to the simulated motion as Circular Motion, whereas it only demonstrates a Uniform Circular Motion where the speed is constant. Also, It would have been very helpful to also show the acceleration vector. Potential effectiveness as a teaching tool - This site provides a decent introduction to uniform circular motion. Ease of use - No particular plugin or application is needed to view the simulation. The site is easy to navigate.

this site was really helpful in aiding my understanding of circular motion, the
problems were especially helpful. kmorgan

The text is clear, and the online quiz is very helpful in preparing students for
exams.
