(a) What is the angular momentum of the Moon in its orbit around Earth? (b) How does this angular momentum compare with the angular momentum of the Moon on its axis? Remember that the Moon keeps one side toward Earth at all times. (c) Discuss whether the values found in parts (a) and (b) seem consistent with the fact that tidal effects with Earth have caused the Moon to rotate with one side always facing Earth.

Definition Definition Product of the moment of inertia and angular velocity of the rotating body: (L) = Iω Angular momentum is a vector quantity, and it has both magnitude and direction. The magnitude of angular momentum is represented by the length of the vector, and the direction is the same as the direction of angular velocity.
Calculate the axial & total angular momentum of the Earth.
Imagine a disc which has a diameter of 2.00m. The angular velocity of the spinning disk is 305rev/min.
a) What is the angular velocity of the disk in radians per second?
b) What is the linear speed of a point on the rim of the disk? (m/s)
c) Find the angular accleration (in revolutions per minute-squared)that will increase the disk's angular velocity to 1000 rev/min in 60 s. Assume the acceleration is constant.
d) How many revolutions does the disk make during this 60 s accleration?
d)
Earth orbits Sun... (Choose the right answer.)
a
Earth orbits Sun in elliptical path at slower speed when it's far from the Sun because its total angular momentum is unchanged
b
Earth orbit Sun in elliptical path at slower speed when it's near the Sun because its total angular momentum is unchanged
c
Earth orbits Sun in circular path with the same speed because its total angular momentum is unchanged
d
Earth orbits Sun in elliptical path at faster speed when it's near the Sun because its total angular momentum changes
e
Earth orbits Sun in elliptical path with same speed because its total angular momentum is unchanged
f
Earth orbits Sun in elliptical path at faster speed when it's far from the Sun because its total angular momentum is unchanged
