In this video, we look at how planets, moons and artificial satellites follow circular orbits. We see how in a circular orbit, the velocity changes but the speed does not. We then explore how if the speed of an object changes, its orbital radius must decrease.

This video is based on the AQA spec. This video may be appropriate for iGCSE / O Level Physics. Please consult your specification. The Amazon link above is an affiliate link.
