What is the force of gravity at Earth's surface?
Rock samples and Indirect evidence from seismic waves.:)
Which planet has little gravity and little atmosphere?
This depends on you definition of little. The best fit would probably be Mercury that has virtually no atmosphere and less than 40 % of Earth's gravity on the surface. (Until 2006 Pluto which has even less surface gravity was a planet as well but is now considered a dwarf planet)
Is the pull if gravity the same all over the earth?
At the surface the force on both the earth and the object is given by: force (newtons) = mass (kg) * acceleration due to gravity (m/s)/s > another way to look at it is , every kg mass has 9.8 newtons of force acting on it.
Why is gravity called a force?
Because it is a force. Gravity is one of the four fundamental forces (gravity, electromagnetism, weak nuclear, strong nuclear or color force).Gravity causes mass to accelerate. F = ma. Gravity must therefore be a force.
Does the moon have a gravitational force stronger than earth?
No. The Moon's mass is only about 1/81 of the Earth, and gravity is dependent on mass and distance. Lunar surface gravity is about 1/6 that of Earth beause the Moon's surface is closer to the center of mass.
What is the force of gravity on the surface of mercury?
About 38% of Earth's gravity.
What is mercury gravity?
The force of gravity on the surface of Mercury is 3.7 ms-2, compared to 9.81 ms-2 on earth.
What is the gravity force of mercury?
The gravity force on Mercury is about 0.38 times that on Earth, which means objects weigh less on Mercury compared to Earth due to its lower gravity. This lower gravity is due to Mercury's smaller mass and size compared to Earth.
What is the gravitational force of Mercury?
Mercury has a force of gravity of 3.7m/s2.
What is Murcurys gravitional force?
The acceleration of gravity at the surface of Mercury is 3.7 m/sec2. The force on a mass on the planet's surface depends on the size of the mass. The magnitude of the force, in newtons, is (3.7) times (the object's mass).
What is the force of gravity of mercury in newtons?
The force of gravity on Mercury is about 3.7 meters per second squared, or 3.7 N/kg. The force of gravity on an object on Mercury will depend on the object's mass.
What is the gravitational force on mercury?
The acceleration of gravity on the surface of Mercury is 3.7 m/s2, compared to 9.8 m/s2 on the surface of the earth. The force between Mercury and any mass there depends on the size of the mass, just as it does on earth. The weight of any object on Mercury would be about 38% of the same object's weight on earth.
What is Mercury's surface gravity in kg?
Local gravity can't be described in units of "kg".The acceleration of gravity at the surface of Mercury is3.697 meters (12.13 feet) per second2 .
What is the force of gravity at the surface on mercury for example what would a 100-pound person weigh on in mercury?
The acceleration of gravity on Mercury's surface, and therefore the weight of anyobject located there, is 37.7% of its value on the surface of the Earth. It followslogically that a person whose body weighs 100 pounds on the Earth's surfacewould weigh 37pounds 11.2ounces on the surface of Mercury just before it beganto vaporize in the bright sunshine there.
Does mercury have more gravity than earth?
Gravity behaves exactly the same on Mercury as it does on Earth. The forces between Mercury and any other mass are proportional to the product of Mercury's mass and the other mass, and inversely proportional to the square of the distance between Mercury's center and the other object's center. Mercury's size is about 38% as big as the Earth's size, which would place the center of an object on its surface closer to the planet's center, and cause a greater gravitational force. But its mass is only 5.5% of Earth's mass. So the force of gravity between Mercury and an object on its surface winds up being only about 37% of the gravitational force on the same object when it's on Earth's surface. That means that a person who weighs 100 pounds on Earth would weigh 37 pounds on Mercury.
How does a planet's size affect its gravity?
The distance between a planet and an object affects the gravitational force between them. That means the size of a planet affects the value of the "surface gravity" for that planet. The greater thedistance from the surface to the center of the planet, the smaller the gravity at the surface (for the same planet mass). An example is the fact that Mars and Mercury have almost exactly the same surface gravity. Mars has more mass than Mercury, but this is balancedby the fact that Mercury hasthe smaller radius.
Is Mercury gravity?
No Mercury, either the metal or the planet is not equal to gravity. Gravity is a force of nature, not a planet or a substance.
