gravitational force act in pairs, and they act toward the center of the earth. does it mean that if u find yourself at the Earth center will your fill weightless?
What do you mean by this? Gravity is most certainly a force in the Newtonian framework. Don't confuse the force of gravity with the strength of the gravitational field, the latter of which is an acceleration.bahamagreen said:Also, gravitation is an acceleration, not a force...
iluvtek said:Although I understand zero gravity does not exist, let's assume deep space is located in area virtually free of any gravitational pull. Wouldn't this be different than having a uniform gravitation force applied from all directions (as is the case with the void in the earth)? If the gravitation pull was strong enough wouldn't this create a type of tensile stress on the astronaut's body?
At Earth's center, the force of gravity is essentially zero. This is because the mass of the Earth is evenly distributed around the center, canceling out the gravitational force.
No, there is no weightlessness at Earth's center. Weightlessness occurs when an object is in freefall, experiencing no force of gravity. However, at Earth's center, the gravitational force is canceled out, but there is still a force present.
At Earth's center, gravity behaves like a point mass, with all of the mass of the Earth concentrated at a single point. This is because the gravitational force from all directions is balanced, resulting in a net force of zero.
No, a person would not experience weightlessness at Earth's center. In order to experience weightlessness, an object must be in freefall, and at Earth's center, the person would not be in freefall but rather experiencing a balanced gravitational force.
No, it is not currently possible to reach Earth's center. The deepest humans have drilled into the Earth is about 7.5 miles, which is only about 0.2% of the distance to the center. The extreme heat and pressure at the Earth's center also make it impossible for humans to reach it.
