J.I. AS101 Reading Question Chapter 4, #34 34. Earth’s angular momentum when it is at perihelion (nearest to the Sun) in its orbit is: (a) Greater than its angular momentum at aphelion. (b) Less than its angular momentum at aphelion. (c) Exactly the same as its angular momentum at aphelion. (b) Less than its angular momentum at aphelion. This is because the angular momentum of an object is defined as its mass times the velocity times the radius.

Unformatted text preview: Angular momentum = mass x velocity x radius In the case of the Earth the mass and velocity stay the same and only the radius changes. Following this formula when the radius is small (perihelion) the angular momentum will be smaller than when the radius is larger (aphelion) the angular momentum will be larger....
