The gravitational pull of the earth on an object is inverselyproportional to the square of the distance of the object from thecenter of the earth. At the earth's surface this force is equal tothe object's normal weight mgmg ,where gg=9.8m/s2m/s2, and at large distances, the force iszero.
If a 40000-kgkg asteroid falls to earth from a very greatdistance away, how much kinetic energy will it impart to ourplanet? You can ignore the effects of the earth's atmosphere.
