Newton's "law" of gravity is a mathematical description of the way bodies are observed to attract one another, based on many scientific experiments and observations. The gravitational equation says …

Jan 2, 2016 · Gravity in Earth’s interior In addition to knowing the gravitational field at different points on the surface, we also have information about how the gravitational field changes as you go deeper …

Jul 20, 2015 · Often students have difficulty reconciling the General Relativity (GR) view of gravity versus their own experience with gravity on the surface of Earth.

Sep 15, 2015 · For two objects with masses, the gravitational force on mass 1 due to the gravitational force of mass 2 can be written as where are the masses of object 1 and 2 respectively, is the …

May 14, 2020 · According to general relativity, gravity is not a force, however it is referred as one of the four fundamental forces. This seems like a contradiction.

Aug 29, 2003 · Both gravity and bouyancy are forces. Gravity causes all mass in the universe to be attracted to all other mass. Bouyancy is a force which is caused by the pressure on the lower portion …

Oct 17, 2022 · From the equation for centripetal force, I can see that the centripetal force is proportional to v^2. Does this have something to do with why there is a normal force at the top? Does the velocity …

May 15, 2024 · A relatively simple question has been bothering me for some time: Why is the weight of an object (the force the object exerts on a surface/rope) equal to the force of gravity that the body …

Oct 7, 2023 · We learned that normal force equal in magnitude as mg and opposite direction, it is reaction force to gravity. 1.If normal force is not equal gravity, isnt this violate newton 3. law …

Jul 4, 2008 · The discussion revolves around two questions regarding the force of gravity. For the first question, the consensus is that statement (c) is false, as it incorrectly suggests that more mass …
