Question

A satellite Is in an elliptical orbit about the Earth. At point X, it is closest to Earth. At point Y, it H furthest from Earth. Point Z is halfway between points X and Y, along the orbital path. Where is the angular momentum (relative to the Earth) of the satellite the highest? A spinning Ice skater is able to control the rate at which she rotates by pulling In her arms. We can best understand this effect by observing that in this process: In rotational dynamics, moment of inertia plays a role analogous (similar) to one of the quantities encountered in linear motion, namely

Explanation / Answer

1. a) It is the same at all locations

2. b) Her angular momentum remains constant

3. C) mass

4. d) 0
