Gravity is zero at any point in the solar system.
Gravity increases with increasing distance.
Gravity increases with increasing distance.
Gravity increases with decreasing distance.
Gravity increases with decreasing distance.
Gravity remains the same regardless of distance.
Gravity increases with decreasing distance.
Gravity decreases with increasing distance.
To understand how distance affects gravity, we need to know that gravity is the force of attraction between two objects. In the case of the solar system, it is the force of attraction between celestial bodies like planets, moons, and the Sun.
The law of universal gravitation, discovered by Sir Isaac Newton, states that the force of gravity is directly proportional to the mass of two objects and inversely proportional to the square of the distance between their centers. This means that as the distance between two objects increases, the force of gravity between them decreases. Therefore, the correct answer is "Gravity decreases with increasing distance."
To find this answer, you can remember Newton's law of universal gravitation, which explains the relationship between gravity, mass, and distance. The farther two objects are from each other, the weaker the gravitational force between them.
