Type of Resource: Video/animation

This online resource is a video in which Catalyst's Dr Derek Muller reveals why objects are apparently weightless in space.

The video first explores some of the common misconceptions people have about gravity and the scale of distances in space for objects in near-Earth orbit before explaining the concept of freefall, which gives rise to the apparent weighlessness of astronauts in space.
