what is the relationship between the strength of a gravitational force and distance?

Gravitational field strength is inversely proportional to the square of the distance from the centre of the Earth. You can also write this as: gravitational field strength is proportional to 1r 2, where r is the distance from the centre of the Earth.

In symbols, the magnitude of the attractive force F is equal to G (the gravitational constant, a number the size of which depends on the system of units used and which is a universal constant) multiplied by the product of the masses (m1 and m2) and divided by the square of the distance R: F = G(m1m2)/R2.

As the height of the object(the distance from Earth's surface) increases, the gravitational force decreases and vice versa. If an object starts free-falling from a certain height, then the gravitational force increases as it falls down reaching a maximum when it touches down.

If the mass of both of the objects is doubled, then the force of gravity between them is quadrupled; and so on. Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.

So as the mass of either object increases, the force of gravitational attraction between them also increases. If the mass of one of the objects is doubled, then the force of gravity between them is doubled. If the mass of one of the objects is tripled, then the force of gravity between them is tripled.

The acceleration on an object due to the gravity of any massive body is represented by g (small g). The force of attraction between any two unit masses separated by unit distance is called universal gravitational constant denoted by G(capital g). The relation between G and g is not proportional.

If we consider Newtonian mechanics, the gravitational force between two massive bodies is given by{ (GMm)/r^2} , Using mks system of units the gravitational force is found to be 1.7847E20 newton. Note: Due to considerations made in average distance between earth and moon, the result can vary slightly.

Gravity is a force of attraction that exists between any two masses, any two bodies, any two particles. Gravity is not just the attraction between objects and the Earth. It is an attraction that exists between all objects, everywhere in the universe.

The Brainliest Answer! Importantance of universal law of gravitation. The gravitational force of attraction of the earth binds all terrestrial objects to the Earth. It explains the attractive force between any two objects which have mass.

Weight is the gravitational force experienced on a body. If you move up to higher altitudes, the distance between you and earth increases. Since gravitational force is inversely proportional to distance multiplied by itself, the gravitational force exerted on your body decreases and so you weigh less.

Gravity is a fundamental underlying force in the universe. The amount of gravity that something possesses is proportional to its mass and distance between it and another object. This relationship was first published by Sir Issac Newton.

This means that gravitational acceleration is inversely proportional to the square of the distance from the centre of Earth. As the distance is doubled, the gravitational acceleration decreases by a factor of 4.

Thinking Proportionally About Newton's Equation Observe how the force of gravity is directly proportional to the product of the two masses and inversely proportional to the square of the distance of separation.

This means that gravitational acceleration is inversely proportional to the square of the distance from the centre of Earth. As the distance is doubled, the gravitational acceleration decreases by a factor of 4. As the distance is tripled, the gravitational acceleration decreases by a factor of 9, and so on.
