If you want me to pick the correct answer from a list of multiple choices for you,
the least you could do would be to let me see the list.
In this case, I can make a pretty good guess, because there are only two things
that can have any influence on the gravitational force between two objects . . .
the masses of the objects, and the distance between them.
The gravitational force between two objects is the result of only two numbers.
So there are exactly two ways to affect the size of the force.
-- Change the product of the masses of the objects, by changing either one or
both of their masses. To increase the force, increase the product of the masses.
-- Change the distance between the centers of the objects. To increase the force,
decrease the distance between their centers.
If we have to increase gravitational force between a chair and the earth, put chair close to center of the earth. As a reference for gravitation force it is always measured from center of two objects. If we move chair away from the center of the earth lets say in space, now gravitational force between chair and the earth decreases.
The gravitational force between two objects increases when either one or both
of their masses is increased, and/or when the distance between their centers is
decreased.
I have the strangest feeling that there's a list of choices that goes
along with this question that you're not letting me see.
Well, no big deal. Almost anybody can answer it if you give them the
multiple choices, but it takes somebody who really knows their stuff
to answer it without the list.
There are only two things that can influence the forces of gravity
between two objects:
-- The masses of the objects. If you want to increase the force,
increase one or both masses.
-- The distance between the centers of the objects. If you want to
increase the force, move the objects closer together.
increase the mass and increase of distance
1) Gravitational attraction increases when distance between the masses decreases.
2) Gravitation attraction increases when mass of the bodies increases.
1). Increase the mass of one or both objects.
2). Move them closer together.
increasing the mass of the smaller object
Because the magnitude of the mutual gravitational force is proportional to theproduct of both masses, so it makes sense that when one of the masses is thewhole Earth, you'd expect the force to be greater than when it's anything elseon Earth.
I would expect the size to increase, because of the repulsive forces between the individual charged particles. I would also expect the effect to be insignificant in most practical cases.
Assuming the only difference is mass and that two objects have the same shape and size, it will take longer for the heavier object to reach terminal velocity than the lighter object. The terminal velocity of the heavier object is greater than that of the lighter object. Since the two objects accelerate at nearly the same rate at slower velocities, the time to reach terminal velocity will increase as weight or mass of the object increases. However I would not expect the increase to be a linear proportion since the drag is proportional to the square of the velocity.
I expect the gravitational force between them will become four times as great as it was originally.
Probably some of the first people to inhabit the earth, now I think about it. However, I expect that you're thinking of Euclid.
As their mass does not change their gravitational force remains the same. For them to move closer together one of the objects must have a stronger gravitaional force than the other. If they collided and became fused together then the gravitaional force would be greater as there would now only be one object.
Because of conditioning. I expect that you would soon notice it if the gravitational constant fell to zero and you were flung off into space! You do not notice atmospheric pressure for a similar reason.
Because the magnitude of the mutual gravitational force is proportional to theproduct of both masses, so it makes sense that when one of the masses is thewhole Earth, you'd expect the force to be greater than when it's anything elseon Earth.
The earth's gravitational pull decreases as altitude increases.
Increase
what can you expect from yourself
Gravity affects objects proportionally to their mass, and electrostatic forces affect objects proportionally to their electrical charge. We can observe that the attraction of the planet Earth for various objects, which we describe as weight, is proportional to mass, not to electrical charge. Consequently we can confidently infer that the attractive force exerted by the planet Earth is gravitational in nature and not electrostatic. It is also true that if there were some enormous electrical charge on the Earth and the moon, causing them to attract each other, we could expect an enormous electrical discharge to take place by which the extra electrons would leave the negatively charged object (moon or planet as the case may be) and travel to the positively charged object.
Increase
I would expect the size to increase, because of the repulsive forces between the individual charged particles. I would also expect the effect to be insignificant in most practical cases.
Increase
increase in CO2 and diminishing of Ozone layer
