 Hi, I'm Joe Hope. I'm a theoretical physicist at the ANU. And hi, I'm Vanessa Roberts. I'm an applied mathematician at ANU. And I'm Adele Morrison. I'm a climate scientist at ANU. And together, the three of us are going to be taking you through the basics of classical mechanics. Classical mechanics is essentially the foundations of physics as a discipline, which started a few hundred years ago. And mechanics is useful for all kinds of things. Some examples are launching satellites into space, figuring out the fuel efficiency of your car, and what I do, which is modeling how ocean currents move.
