## How do you find the height of gravitational force?

The change in gravitational potential energy, ΔPEg, is ΔPEg = mgh, with h being the increase in height and g the acceleration due to gravity. The gravitational potential energy of an object near Earth’s surface is due to its position in the mass-Earth system.

## How many km of gravity is on earth?

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.)

**Does distance determine gravitational force?**

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 two objects are separated from each other, the force of gravitational attraction between them also decreases.

**How do you find mass with height and gravity?**

For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.

### What is the magnitude of the gravitational force between Earth and a 1 kg object on its surface?

What is the magnitude of the gravitational force between the earth and a 1 kg object on its surface? (Mass of the earth is 6 × 10^{24} kg and radius of the earth is 6.4 × 10^6 m). This shows that Earth exerts a force of 9.8 N on a body of mass 1 kg.

### What will happen if there is no attraction coming from the earth?

Without gravity, the air in the atmosphere has no reason to hang around, and it would immediately leap into space. Without an atmosphere, any living thing would die immediately and anything liquid would boil away into space. In other words, no one would last long if the planet didn’t have gravity.

**Where is the highest gravitational acceleration on Earth?**

The highest gravity on earth occurs at the surface of the Arctic Ocean, at 9.8337 m/s2.

**How do you calculate the force of gravity on the Earth?**

On the surface of the Earth, it’s value is 9.8 meters per square second or 32.2 feet per square second. ge = G * m earth / (d earth)^2. The weight W, or gravitational force, is then just the mass of an object times the gravitational acceleration. W = m * g.

#### How is the distance of an object from the Earth measured?

For objects near the Earth , the sum of the mass of all the particles is simply the mass of the Earth and the distance is then measured from the center of the Earth. On the surface of the Earth the distance is about 4000 miles.

#### What is the value of G at the height 3600km above Earth?

Looks like about 4 meters per second squared, compared with 9.8 for g, so the answer is about 0.41 g. Originally Answered: What is the value of g at the height of 3600km above the surface of earth? Man, those are some detailed answers for such a simple question.

**What is the ratio of the gravitational constant to the Earth’s mass?**

We can calculate the ratio of the gravitational constant to the value at the surface of the Earth as the square of (4000/4007) which equals .9965. If the rocket weighs 100 pounds on the surface of the Earth, it weighs 99.65 pounds at 35000 feet; it has lost .35 pounds, a very small amount compared to 100 pounds.
