The acceleration due to gravity is almost constant during the entire flight. A minimal difference is found due to altitude, the further away from the center of the earth, the less the gravitational acceleration, so in a SAM the point when the missile is at it's greatest altitude will have the lowest gravitational acceleration component.
The acceleration of gravity at its surface is currently estimated as 0.4 m/s2 .That's about 4% of the acceleration of gravity on the Earth's surface.
Because the acceleration of gravity on the surface of any given body depends on the mass of the body and its radius ... the distance of the surface from the center. Mars' mass ... about 11% of Earth's ... and Mars' radius ... about 53% of Earth's ... combine to produce about 38% of Earth's gravitational acceleration at the surface of Mars.
its 13.6
9.81 is the acceleration due to the force of gravity experienced by bodies on or about the surface of the earth (nominally at sea level) the units are meters per second / per second, that is to say a stone dropped from a height will gain 9.81 m/s velocity for every second it falls (is in freefall) however , if you move from the earths surface , this figure will diminish, an example being : if you double your distance from the earths centre you will experience 1/4 of the acceleration (or force) you experienced at the surface
The acceleration affects the weight of the person and object
Force = Mass x Acceleration F = ma W=mg It is the intensity of the gravitational field. The acceleration. due to gravity is the force experienced by a body of unit mass in a gravitational field. it is the force experienced by a body of unit mass towards the centre of the earth by the pull of the earth.
The acceleration due to gravity on or near the Earth's surface is about 9.81 meters per second2 . The forces of gravity between the Earth and a mass on or near the surface are 9.81 newtons per kilogram in each direction.
weight
The force of gravity on the earth is 9.8 m/s^2
The acceleration of gravity at the 'surface' of Jupiter is 2.639 times its value at the Earth's surface.
On the surface of Venus, the acceleration of gravity, and therefore the weight of any object, is 90.3 percent of what it is on the surface of Earth.
The acceleration of gravity on the surface of Mercury, and therefore the weight of any mass located there, is roughly 37.7% of what it is on Earth's surface.
