Is earths surface shapes mainly by water running downhill?
Because of gravity.
What force of gravity is on the surface of mercury?
3.7 m/s2 or 0.38 g
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.
Why do earth and the moon remain in their orbits?
(simplified) Gravitational force of attraction is balanced by centripital force due to earths velocity. (G*m1*m2) / r2 = m2 * (v2 / r) m1 = sun mass m2 = earth mass r = earth - sun distance v = earths orbital velocity G = newtons gravitational constant
What is the force on the Moon's surface compared to the force of gravity on earths surface?
The moon's gravity is about 1/6th of the earth's.
Which fundamental force of nature is responsible for keeping you on earths surface?
Gravity.
What force holds the atmosphere to earths surface as it travels through space?
Gravity.
What is mars gravity force earths gravity equals 1?
No, Its gravity is much lower due to a lower overall mass of the planet. Mars' gravity is about 37.6% of the Earths.
What is the surface gravity on earth?
The force of gravity on the earth is 9.8 m/s^2
Why is gravity strongest at Earth's surface?
Gravity is strongest at the earths surface because it's atmosphere is v dense and so the force inc.this happens because force is directly proportional to density.
On earths surface how much force does the pull of gravity have on 1 kilogram of mass?
9.8 newtons, down
How does rotation affect the value of gravity at the earth surface?
The (centripital) force due to rotation is at its greatest at the equator, if you weigh 100 kg, the force of gravity on you = approx. 982 n anywhere on earths surface, the centripetal force at the equator = 3.4 n
Which force acts from a distance to play a role both in the formation of tides and mass movements on earths surface?
Gravity.
What is the Suns gravity in relation to Earths gravity?
The Sun's gravity, at its surface, is about 28 times Earth's surface gravity.
How much more is Earths surface of gravity than the Moon's?
Earths surface of gravity is 4.6m/s2 more than moons.
What is the compare of the earth and the moon in terms of size and surface gravity?
earth is 81.3 times the mass of the moon . acceleration due to gravity at earths surface = 9.82 (m/s)/s acceleration due to gravity at moons surface = 1.62 (m/s)/s . 1 kg at earths surface, force = 1 * 9.82 = 9.82 newtons 1 kg at moons surface, force = 1 * 1.62 = 1.62 newtons
