## What are the factors affecting G?

Solution : The value of the acceleration due to gravity, g, changes from place to place on the earth.

It also varies with the altitude and depth below the earth’s surface.

The factors affecting the value of g are the shape of the earth, altitude and depth bleow the earth’s surface..

## What is difference between G and G?

Difference between g and G in tabular form The basic difference between g and G is that ‘g’ is the Gravitational acceleration while ‘G ‘ is the Gravitational constant.

## What is the effect of shape of Earth on value of G?

Thus, acceleration due to gravity at a place is inversely proportional to the square of the distance of the point from the center of earth. Now, the earth is not perfectly spherical. It is flattened at the poles and elongated on the equatorial region is approximately 21 km more than that at the poles.

## At what height is there no gravity?

Near the surface of the Earth (sea level), gravity decreases with height such that linear extrapolation would give zero gravity at a height of one half of the Earth’s radius – (9.8 m·s−2 per 3,200 km.) and altitude h in metres.

## What two factors affect gravitational?

The factors that affect an object’s gravitational potential energy are its height relative to some reference point, its mass, and the strength of the gravitational field it is in.

## Which factors affect gravitational force?

Newton’s law also states that the strength of gravity between any two objects depends on two factors: the masses of the objects and the distance between them.Objects with greater mass have a stronger force of gravity between them. … Objects that are closer together have a stronger force of gravity between them.

## Does height affect gravitational force?

gravity increases with height. gravity is significantly less on high mountains or tall buildings and increases as we lose height (which is why falling objects speed up) … gravity affects things while they are falling but stops when they reach the ground. It does not operate on things that are moving upwards.

## What two factors will make an object stable?

The stability of an object is dependent on two factors:The base width of the object.The center of gravity.

## What is the value of G?

9.8 m/s2In the first equation above, g is referred to as the acceleration of gravity. Its value is 9.8 m/s2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2. When discussing the acceleration of gravity, it was mentioned that the value of g is dependent upon location.

## Does gravitational force increase with mass?

Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.

## What is gravitational constant?

n. The constant in Newton’s law of gravitation that yields the attractive force between two bodies when multiplied by the product of the masses of the two bodies and divided by the square of the distance between them.

## What are 3 examples of gravitational potential energy?

Examples of Gravitational Potential EnergyA raised weight.Water that is behind a dam.A car that is parked at the top of a hill.A snow pack (potential avalanche)A yoyo before it is released.River water at the top of a waterfall.A book on a table before it falls.A child at the top of a slide.More items…

## What is an example of a gravitational force?

The force that holds the gases in the sun. The force that causes a ball you throw in the air to come down again. The force that causes a car to coast downhill even when you aren’t stepping on the gas. The force that causes a glass you drop to fall to the floor.

## How does mass affect gravitational force?

Anything that has mass also has gravity. Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is.

## Why the value of g is constant?

The force of attraction between any two unit masses separated by a unit distance is called universal gravitational constant denoted by G measured in Nm2/kg2. … The value of the gravitational constant is the same throughout the universe. The value of G is different from g, which denotes the acceleration due to gravity.

## How Does height affect force?

The change in velocity is very small, and the change in time is small. When you hit the ground falling from 50 meters, the change in velocity is very large, and the change in time is small. This means the hitting force goes up, or is proportional to the initial height. Bigger fall, results in a bigger force.

## Does gravity affect weight?

Weight is a measure of how much gravity pulls on a mass or object. On the moon, there is less gravity pulling on objects, so they weigh less. For example, a rock that weighs one pound while on Earth will weigh less than that if it is taken to the moon.
