Just goes to show how important it is to have more than one source!“E. "Big Bang"- a big group of mass starts spinning with no force to make it do that, and it gathered into one big ball of mass. Then somehow exploded. Then made all the stars in the universe. The Planets: Nepute, Pluto, and Uranus spin backwards, yet the law of 'angular mo-mentum' states when any gathering of mass implodes or explodes, all the remains, or planets, will spin in the same direction. BOOM. FALSE.”

I dunno what this is supposed to describe but it sure as Hell isn’t Big Bang.
The law of conservation of angular momentum:The angular momentum of a rigid object is defined as the product of the moment of inertia and the angular velocity. It is analogous to linear momentum and is subject to the fundamental constraints of the conservation of angular momentum principle if there is no external torque on the object. Angular momentum is a vector quantity. It is derivable from the expression for the angular momentum of a particle
IF THERE IS NO EXTERNAL TORGUE… But guess what, moron. Asteroids and comets have col-lided with the planets since they were formed. So there… nahnah.
Idiot.Momentum = Mass moving with constant velocity = mass times velocity
Angular momentum = Mass moving in a circle = moment of inertia cross-product angular ve-locity.Easy to confuse the two, I agree. However, neither momentum nor angular momentum can be conserved in the solar-system, because things collide.
only a few more weeks and I'll be able to understand that. I'm assuming our lessons in cicluar motion will lead to angular motion in my physics class.
