Suppose that two objects attract each other with a gravitational force of 10 Newtons. If the distance between
the objects was 1/2 the original distance AND the mass of
BOTH of the objects decreased by 1/2, what would the new
force of attraction between them be? (include the
magnitude and units in your answer).

it is called kinetic energy

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

no

explanation:

no i dont know how to solve this you should probably try to google the answer
