Orbits

Today we discussed two types of orbit. Circular orbits (involving satellites around a planet), and elliptical orbits (planets around the sun).

For circular orbits we can equate centripetal force with the force due to gravity to arrive at a formula for orbital velocity:


While for planetary orbits we looked at Kepler's Laws.

I also gave you an old exam to study from so please use your time well this week since our exam is only a week this Friday away.
