The list of choices that you posted along with your question
doesn't include any such object.
If you have a better list there, then just select the heaviest item from it.
On the earths surface gravity pulls you down.
Gravity
B
The forces of gravity that attract the Earth and an object on its surface toward each other are greatest for the object with the greatest mass. Among the items on your list, that's probably the house.
because of gravity
its a house
The answer is B. A house.
The asteroid belt does not have a surface as it is not an objects. It is a loose scattering of objects.
On the earths surface gravity pulls you down.
The object with the greatest mass.
Gravity
Objects with the greatest mass will have the greatest force of gravity attracting them to the surface of the earth. Gravitational attraction is based on the mass of an object and the distance between the two "attractors" involved. For things on the Earth's surface, more mass equates to greater gravitational attraction. It's a direct relationship.
B
Gravity, easy!
no it is false
Mainly gravity, and air resistance.
Gravity acts on an entire object, not just on its surface. I don't think there is any physical relevance to investigate only the gravity on a surface, and such a thing definitely doesn't have a special name.
