Is There Gravity In Space?

In this mini-lecture, Dr Pete Edwards (Durham University) discusses gravity in space, focusing in particular on: (i) a demonstration that involves wringing out a wet washcloth in the International Space Station that is orbiting around Earth (done by astronaut Chris Hadfield); (ii) Newton’s Cannon, a thought experiment that helps us understand orbits and the concept of freefall; (iii) a video of an astronaut bunny hopping on the Moon; (iv) gravity on Earth (10 N/kg) compared to gravity on the Moon (1.6 N/kg); (v) the relationship between mass and gravitational field strength; (vi) orbits, which involve an acceleration due to the change in direction of the orbiting object; (vii) and a demonstration of the relationship between radius and velocity of an object in orbit. This lecture is part of a larger course on Exploring the Universe. The full course can be found here: https://www.massolit.io/courses/explo...
