Gravity is 9.8 m/s per second
its actually 9.8
9.8 meters per second square
The standard value is 9.80665 ms-2.
Its standard value is 9.80665
Yes. It's a fine acceleration value, with proper units and dimensions. It's roughly 31% of the acceleration of gravity on earth.
Gravity is about 9.8 meters/second2. This refers to planet Earth, near the surface. The value varies a bit from one place to another. For example, it varies with latitude.
9.8
The acceleration of gravity on or near the surface of Venus is 8.87 m/s2 . . .about 91% of its value on or near the surface of Earth.
I presume you mean acceleration due to gravity on earth (ignoring any air resistance). It is approx. 9.81 ms-2.
It is the approximate value of the acceleration due to gravity on the surface of the earth.
That all depends on where you are. On the surface of the Earth, it's 9.807 . It's 1.623 on the surface of the moon, and 3.711 on Mars. (All rounded.) And it's not an "acceleration force". It's just acceleration. To get a force, you have to multiply acceleration by a mass.
