* a...
Episode 223: Preparation for Circular Motion Topic
These resources, produced by the Institute of Physics, look at circular motion, which is frequently observed in nature. Once students have a grasp of the mechanics of linear motion in one or two dimensions, it is a natural extension to consider circular motion.
There are two learning episodes in this topic...
Episode 224: Describing Circular Motion
From the Institute of Physics, this learning episode introduce students to the importance of circular motion and the need for a centripetal force to keep an object moving along a circular path. The activities include: * observing circular motion * whirling bucket and centripetal force * discussing examples of...
