So is the strength of gravity proportional to the speed of acceleration of gravity? So would an object with 2g of gravity have a 19.62 m/s^2 acceleration? I am sure this sounds like a stupid question

Eh, come on phinds, that looks like it's meant to be "magnitude of acceleration due to gravity".phinds said:I wouldn't say it is a stupid question, I'd say it is an incomprehensible question. What is the "speed of acceleration of gravity" ?

Here's your belated award:
Sure, you can say that the strength of Earth's gravitational field (near the surface) is 1g.lundyjb said:Haha sorry. Isn't Earth gravity acceleration something like 9.81 m/s^2? We also describe Earth's gravity as being 1g (I assume the g stands for gravity, if not, please tell me).
Still not quite sure what you mean. Are you asking: If the strength of the gravitational field were twice as much, would a falling object have twice the acceleration? If so, then yes.So would an object with a gravity of 2g have an acceleration of 2*9.81 (19.62) or is the 9.81 a universal rate of acceleration? (Sorry meant to say rate, not speed of acceleration)
Something like that. The acceleration due to gravity is inversely proportional to the square of the distance from the Earth's center. Since the radius of the Earth is about 6.4 x 106 kilometers, if you were that distance above the Earth's surface (which is quite far) the acceleration would be 1/4 as much as it is on the Earth's surface.lundyjb said:Ahh i see. So theoretically, something falling towards the Earth will have an acceleration slightly less than 9.81 (proportional to its distance from the surface) until the instant it hits the surface?

The strength of gravity is a measure of the force of attraction between two objects due to their mass and distance from each other. It is responsible for keeping objects on Earth and other planets in orbit around the sun.
The strength of gravity can be calculated using Newton's Law of Gravitation, which states that the force of gravity is directly proportional to the product of the masses of the two objects and inversely proportional to the square of the distance between them.
Yes, the strength of gravity varies on different planets depending on their mass and size. For example, the force of gravity on Earth is stronger than on the moon due to its larger mass.
The strength of gravity cannot be changed as it is a fundamental force of nature. However, it can be affected by factors such as the mass and distance of objects, as well as the presence of other gravitational forces.
The strength of gravity plays a crucial role in understanding the behavior of celestial bodies and in predicting their movements. It also has important implications in fields such as astrophysics, space exploration, and satellite technology.
