WebSep 12, 2024 · Take the cross product →l = →r × →p and use the right-hand rule to establish the direction of the angular momentum vector. See if there is a time dependence in the expression of the angular momentum vector. If there is, then a torque exists about the origin, and use d→l dt = ∑ →τ to calculate the torque. WebThe total angular momentum is the sum of the spin and orbital angular momenta. In the case of the Earth the primary conserved quantity is the total angular momentum of the solar system because angular momentum is exchanged to a small but important extent among the planets and the Sun.

Web(a) Calculate the orbital angular momentum of the moon. (b) Take Ls = 5.9 × 10 33 kg · m 2 /s for the earth today, and calculate the radius of the moon's orbit back when the length of the day was 10 hr instead of 24 hr. Assume that Ls α 1/ T, where T is the length of the day. ( Hint: Use Example 6 .) 27. WebJan 1, 2024 · Many interesting results about angular momentum have been analyzed and reported such as the spin–orbit interaction [37,38], and the angular momentum of … WebThe spin angular momentum of the Earth–Moon system is anomalously high compared with that of Mars, Venus, or the Earth alone. Some event or process spun up the system relative to the other terrestrial planets. However, the angular momentum of the Earth–Moon system (3.41 × 10 41 g·cm 2 /s) is not sufficiently high for classic fission to ... bai 74
