  1. Gravity and OrbitsTrish Loeblein 2/20/11 Only one question at present and it deals with vector representation of forces on moon. Learning Goals- Students will be able to Draw motion of planets, moons and satellites. Draw diagrams to show how gravity is the force that controls the motion of our solar system. Identify the variables that affect the strength of the gravity Predict how motion would change if gravity was stronger or weaker.

  2. If our sun were twice as massive, how might the earth movement change? C. The path would not change The earth would definitely crash into the sun B. The path would be smaller

  3. Which vector representation would show the moon between the earth and the sun? (black arrow Total Gravity Force moon) B. C.

  4. Use the simulation to show the path of the moon and the resulting vectors. Remember that the placement of vectors in space is arbitrary. The point (0,0) can be anywhere.
