The problem is was - and still is - that due to Earth's gravity, to completely leave the Earth, an object must have an initial speed of about 11.2 km/second - or it must in some way (for example, with a hypothetical space elevator) be provided with the equivalent energy.

Is gravity different from England in Australia?

Not so you would easily notice. Gravity at the earths surface varies slightly all over the planet.


Why gravity becomes zero at equator?

Gravity doesn't become zero at equator, its value is roughly the same all over the earths surface.

What is the comparison between the earths gravitationnal force with mercury?

The gravity of Mercury is approximately 38% that of Earths gravity at the surface.Here are some comparisons:A 150 lbs person would weight 57 lbs on Mercury.You would be able to jump about 2.63 times as high on Mercury making a person capable of jumping over their head doing a standard stationary vertical jump.The moon's gravity is 16% of the Earths gravity as opposed to Mercury's 38%


What planets gravity is one-fourth the gravity of earth?

Of the planets in our solar system, Mars has the lowest surface gravity of around 38% of earths - over one third. This comes closest to the 25%. We then have moons and dwarf planets, but these have much lower surface gravities.


When does gravity change?

Gravity is caused by mass. Everything causes gravity but the bigger it is and more mass it has the more pull is felt by its gravity. So you are pulling the earth towards you and the earth is pulling you. The earth is much bigger and has more mass, so it pulls much more. Gravity gets weaker the further away you get from its source. The earths crust does not have the same mass all over, so some areas have slightly less gravity than others. The differences between areas are very very small. The moon has only a quarter the mass of the earth, so gravity on the moon is a quarter of earths gravity.


How do gravity affect earths crust?

Gravity constantly pulls on the Earth's crust, causing it to deform and shift over time. The force of gravity also plays a role in driving tectonic plate movements, which result in earthquakes, mountains, and other geological features. Overall, gravity contributes to the dynamic nature of the Earth's crust.

How is gravity involved in the erosion of earths surface by mass movement?

Gravity plays a key role in mass movement erosion by pulling rock and soil down slopes. When gravity overcomes the resistance of friction and cohesion holding the material in place, mass movement processes like landslides, rockslides, and mudslides occur. Gravity acts as the driving force that causes the material to move downslope, shaping and reshaping the Earth's surface over time.

Can earths gravity increase or decrease?

Yes, it is not a constant. The force of gravity is related to the distance from the centre of the earth so that the force of gravity will be slightly reduced at altitudes. Also, the earth is not a perfect sphere - it bulges at the equator and is flatter at the poles. So the force of gravity will be greater at the poles. The force of gravity is also affected by what is under the surface: if standing over dense rocks, the force will be greater. Finally, the force of gravity is also higher after heavy rainfall. [I guess that is because the water fills up all the air gaps in the soil and so increases its density.]
