A ball is thrown up at 12m/s. Assume no air resistance and you have to assume that the gravitational field is constant at 9.8ms^-2 then
(for this x will represent the number of seconds since the object was first at a height of 0m)
to work out the speed at each point in time we use the equation 12-9.8x
the 12 is the original speed and the -9.8 is the acceloration towards the earth and the x is the seconds if we calculate the units
12m/s+(-9.8m/s/s*xs) = 12m/s + (-9.8x)m/s this means that the end units are m/s which is speed.
to work out the position we have to times by time again to get m
so the (position at time x) = 12x+(-9.8)*(x^2)
then to find the highest point use the formula x=-b/2a which in this case as we are using the quadratic -9.8x^2+12x+0
-b = -12
2a = -19.6
-12/19.6 = about 0.61 seconds (this is at what time it reaches its highest point) as we have x we can work out the height which is
-9.8(0.61)^2 +12(0.61)+0 = 3.67m
so in answer to the question proposed as an answer for the original question the object would reach 3.67 meters
I think you need to try and clear up what you actually want as an answer for the original question before you can get a proper answer to it.

g = GM / (R + h)2
Where:
g = Acceleration Due To Gravity
G = The Gravitational Constant (=6.67300 x 10-11)
R = The Radius of the body (For earth this is 6378.1)
h = The height above the surface
Weight = (mass)(acceleration due to gravity). On Earth, the acceleration due to gravity is 9.82 m/s2.
You can use a simple pendulum, measure how long one period takes, then use the formula for a pendulum, and solve for gravitational acceleration.
Potential Energy=mass*acceleration due to gravity*height. PE=mgh The acceleration due to gravity= 9.8m/s
I suppose you are asking about what forces change when acceleration due to gravity changes. In this case, the formula for forces concerning acceleration due to gravity is as such: fg=mg. When acceleration due to gravity(g) changes, it affects the force of gravity which is also known as the weight of the object. This is shown as fg.
Mass = force ( weight) / acceleration due to gravity
Gravity and acceleration are definitely NOT the same. Gravity and acceleration can have the same EFFECTS.Dark matter is some unknown substance, which provides gravitational attraction. As a result, just like any regular matter, it will accelerate any nearby matter. But calling it "dark acceleration" doesn't really solve the mystery of what it's made of.
WEIGHT IS EQUAL TO MASS INTO ACCELERATION DUE TO GRAVITY. MATHEMATICALLY: W=mg
Weight=m*g m=mass g=acceleration of gravity
The acceleration due to gravity at sea level at the equator is 32.25744 feet/second2 (983.2186 cm/second2)Formula for your own altitude:Acceleration Due to Gravity (cm/s2) at Altitude (h) = Acceleration Due to Gravity (cm/s2) at Sea Level - 0.3086hwhere h is the altitude in kilometers.
Not at all. However Gravity can impart an acceleration - Gravitational acceleration.
Acceleration does not effect gravity. It is rather the other way round. Gravity can affect the rate of acceleration.
E (joules) = mgh where: m = mass (Kilograms) g = acceleration due to gravity (metres per second squared) h = height above ground (or lower boundary) (metres)
