What concepts would you use to describe the asteroid's motion?
If the asteroid is moving at a constant speed in its orbit, does
this also mean it is moving at a constant velocity? Explain your
answer.  Based on your answer above, is the asteroid
accelerating? Explain.  What force acts to hold this massive
object in orbit around the Sun? What direction does this force
act?  This asteroid's motion is affected by many different
massive objects. Rank the following in order of increasing
influence: the Sun, Mars, Jupiter, and other asteroids. Explain
your answer clearly and specify the main determining factor for
each body.  Assume this asteroid has the shape of a sphere. A
rock sitting on the surface of the asteroid has a weight of 100
newtons. What would the weight of this rock be if it were moved
to a distance above the surface equal to the radius of the
asteroid? It may be helpful to draw a picture to better
visualize what is going on. How is the mass of the rock affected
by its change in position?  At some p
