How much work is done by the Moon's gravitational field as a 1005 kg meteor comes in from outer space and impacts on the Moon's surface?


asked by Rachel
  1. mMG/R

    where R = moon radius
    G = universal constant of gravity
    M = Moon's mass
    m = 1005 kg

    You will need to look up G, M and R and do the calculation.

    The number you get will probably be small compared to the kinetic energy of the meteor before entering the moon's gravitational field.
