Learning Module 3 Connor MacLeod 100254620 The first video, The Solar Nebular Theory, describes the planetary formation through a collapsing cloud of dust and gas that spins in the same direction at a fast pace. Through angular momentum, as it collapses even more, it speeds up and flattens into a disk. As it flattens, the materials start to come together and planets start to form as well as a young star is created in the middle. What I liked about the video is how they used good analogies such as the pizza and the figure skater to get the idea of angular momentum across. What I didn’t like about the video is how they didn’t go more in depth about the other bodies that are created around the star. To make it better I would’ve used our …show more content…

The pull of Jupiter’s gravity kept the particles accelerating so fast, they could never accrete.
