It's either a comet or meteorite.
gravity
The force of mutual gravitational attraction between the earth and any other object pulls the object toward the center of the earth, and pulls the earth toward the center of the object. Both pulls have equal strength.
The centripetal force is responsible for pulling objects toward the center of a circle as they move in a curved path. This force acts perpendicular to the velocity of the object, keeping it on a circular trajectory.
Gravity is the cause of a pair of forces that attract any two specks of mass toward each other. The forces act along the line between the centers of the objects. As long as you're anywhere near Earth, the forces of gravity pull the Earth toward the center of you, and pull you toward the center of the Earth (and they're equal).
Pressure increases as you travel toward the center of the Earth due to the weight of the overlying rock and material pushing down. The high pressure at the Earth's core is believed to be extreme, over 360 GPa.
Toward the center of mass of the object or objects attracting you. Gravity also pulls it/them toward the center of mass of you.
The resistance will increase
Centripetal force is the force toward the center of a circular path. It is often confused with centrifugal force, which is the force away from the center.
9 feet in toward the exact center.
The ball speeds up as it travels to the ground as gravity pulls it down to make it go fast.
Yes. Sort of. If you consider the rotating system from the point of view of somebody OUTSIDE the system (not participating in the rotation), no "centrifugal force" is required to explain anything; there is an unbalanced centripetal (center-seeking) force, which accelerates whatever rotates, toward the center.

Toward the center of mass of the object

The ideaitself tend toward the "heaviest" center was basis of the geocentric system. Copernicus argued that movement was basis of that system is only perceived, not real and used examples to predict the movement of planets to support his own theory
Gravity is the force that causes objects to move toward the center of the earth. This force is proportional to the mass of the object and the mass of the earth, and it decreases with distance from the center of the earth.
An incident light ray is a light ray that travels toward a reflective surface. When this ray hits the surface, it may be reflected, refracted, or absorbed, depending on the properties of the surface and the angle at which the light ray strikes it.
