What Relationship Did Newton Find Between Orbital and Escape Velocities

question 71

Essay

What relationship did Newton find between orbital and escape velocities? Relate this to thestaging of the Apollo missions, first to a parking orbit about the Earth, and then on to the Moon.

Definitions:

Inductance

The property of an electrical conductor by which a change in current flowing through it induces an electromotive force in both the conductor itself and in any nearby conductors by mutual inductance.

Wire Resistance

The electrical resistance of a wire, determined by its material, length, and cross-sectional area, affecting the flow of electric current through it.

Fleming's Left-hand Generator Rule

A rule used to predict the direction of movement in a motor, the direction of induced current, or the force on a conductor in a magnetic field, based on the thumb, forefinger, and middle finger of the left hand.

Time Constant

The time required for a system to charge or discharge to approximately 63.2% of its maximum value, characteristic of both RC and RL circuits.
