It turns out that gravity can be described as either a theory or a law.
Every time I pick up something and let it og, it falls to the ground. This is repeatable and I can masure the rate of fall through equations. Acceleration due to gravity:
g = 9.8 m/s/s, downward
Just two ways to explain gravity (there are more out there) (very simplified):
In this session, we will exlore the effects of gravity on the Sun-Earth-Moon system.
