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
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
Yes, that is Newton's law of gravity
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.
The gravitational constant G = 6.67259 * 10^-11 Newton meters^2/kg^2
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
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 :)
yeah, I guess. :-\
