6 April 2018 Astronomy Lesson

6 April 2018

Today, we learned more about Orbital Mechanics such as the different types of orbits (elliptical, parabolic etc.) and about Kepler's Laws. Kepler's Laws are especially important in understanding how planets and other celestial bodies orbit each other.

Another equation we learned about is the equation for Angular Momentum. L = tangent velocity x radius x mass. Using this equation, we would be able to calculate the angular velocity of objects in orbit. A practical application of angular momentum is in the calculations of angular velocity of objects in Earth's orbit (e.g. Satellites) to ensure that they are at the minimum speed to stay in orbit above Earth.

We also started planning the design for our rockets that we will be building and launching next week. Chris and I planned a rocket design with a 1.5 litre bottle which we want to attempt to modify by adding chemical boosters :D
