Which one of the following objects will have the greatest force of gravity to the Earth at its surface

. A large book
B. A house

C. A human being

D. An average-size car
i don't get it??

    Well I think that the question means which of the follwing objects will have the greatest force of weight to the earth at its surface. I think the answer is a house

  • earth science - ,

    F = G m Mearth / Radius earth^2
    all the same for each object except m
    so the biggest m gives the biggest gravitational force
    Houses generally have more mass than even the largest cars.

    Is this a common formula used

  • earth science - ,

    Yes, that is Newton's law of gravity

  • earth science - ,

    force between two masses equals Newton's gravitational constant times the product of the two masses divided by the square of the distance between them.

  • earth science - ,

    The gravitational constant G = 6.67259 * 10^-11 Newton meters^2/kg^2

  • earth science - ,

    Mass of earth = 5.98 * 10^24 kilograms
    radius of earth = 6.38 * 10^6 meters

    oh, i was just asking, because i really don't get any of this stuff

  • earth science - ,

    That is the famous one though, about the mythical apple falling on Newton's actual head and him coming up with the law of gravity as a result.

    oh I heard about the one, but I can't remember but it was about a crown. By the way I'm only in grade 8, these things r way toooooo difficult 4 me

    Well, your answer was correct anyway :)

  • earth science - ,

    yeah, I guess. :-\
