WebNov 29, 2024 · An object can move uniformly in a line by inertia without any force being applied, forces are needed only for acceleration. If you consider force fields to be "objects" then all forces come from "objects" in "physical contact" with them, modern physics does not admit action at a distance (as gravity was once thought to be). WebKey points: The force of gravity, or gravitational force, pulls objects with mass toward each other. We often think about the force of gravity from Earth. This force is what keeps your body on the ground. But any object with mass exerts a gravitational force on all other objects with mass. For example, there is a gravitational force between you ...

WebApr 5, 2024 · Gravity is a force of attraction between any two objects. That attraction is stronger when the two objects are more massive. It’s also stronger when the objects are closer together. Earth’s gravity holds your feet on the ground. This gravitational tug is so strong because Earth is so massive and so close. But gravity acts over any distance. WebSep 1, 2024 · The amount of gravitational force between two objects will depend on two things: the masses of the two objects and the distance between them. The mass of each object is proportional … WebThe truth is, gravity does not "pull" objects at all; rather, gravity warps spacetime, causing objects to follow the bends that are created and, as a result, they sometimes accelerate.
