Satellite Motion Summary of Terms: Satellite:  A projectile or small celestial body that orbits a larger celestial body. Ellipse:  The closed oval-like curve wherein the sum of the distances from any point on the curve to both foci is a  constant. When the foci are together at one point, the ellipse is a circle. The farther apart the foci, the more eccentric the  ellipse. Escape Speed:  The speed that a projectile, space probe, or similar object must reach to escape the gravitational  influence of the earth or celestial body to which it is attracted. Equations, Equivalences, and Concepts: The sum or KE and PE for a satellite is a constant at all points along its orbit. For a satellite in circular orbit, it is always moving perpendicularly to the earths gravitational field. Because a satellite moves at right angles to the earths gravitational field, no change in speed occurs - only a  change in direction. The higher the orbit of a satellite, the less its speed and the longer its period. Electricity The force between two electrically charged objects is F=(Kq1q2)/r^2 (r=distance, q=charges, k=proportionality constant) E = Elemental electric charge (-1.6 x 10-19 Coulombs) Conductor  - allows electric charge to move thru it Insulator  - materials in which the electrons are tightly bound E=F/q F=Eq A=F/M=Eq/M W=FD=EqD 1 Volt=1 Joule/1 Coulomb
