One elegant way to measure the acceleration of gravity at the place where you are
is to measure it with a swinging pendulum. You must be able to measure the length
of the pendulum, and the time of its swings, very accurately, and you must enclose it
in some sort of a can or a box in order to keep air currents away from it.
When you've measured its length ( ' l ' ) and the time of its swing ( ' T ' ), the acceleration
of gravity ( ' g ' ) is
g = T2/(4π2l)

What is the planet earth's gravitational force?
This can be measured by the acceleration due to gravity at the surface. Earth's surface gravitational acceleration is about 9.8 m/s2
What is the gravitational acceleration at the altitude of 200km?
8.97m/s
Why is the gravitational accleration of any object near Earth is the same?
The earth creates a gravitational acceleration field around the earth and objects in that field experience the same acceleration field.
How do you find the weight of an object on earth?
You could weigh it against other objects. If it is not on the surface, multiply its mass by the acceleration of gravity (at that distance) to find its gravitational potential in newtons.
What is the magnitude of the acceleration of an object free falling for 3 meters in the first second on a planet with no atmosphere?
The magnitude of acceleration depends on the gravitational pull from the planet. The amount of gravitational pull depends on the size and mass of the planet. On Earth gravity will produce an acceleration of 9.8 meters per second squared if there was no atmosphere.
What is the difference between gravitational acceleration and acceleration?
Gravitational acceleration is simply acceleration due to gravity.
Is gravitational pull the same as gravitational acceleration?
No. "Pull" is a force, not an acceleration.
When acceleration upward or downward direction is taken positivw or negative?
If it is gravitational acceleration then it it is positive in downward and negative in upward direction..if it is not gravitational acceleration then it is depending upon the value of acceleration.
How do you find acceleration due to gravity when gravitational constant is given. tell the formula?
Acceleration due to gravity in the vicinity of a mass 'M' is A = G M / R2 A = the acceleration G = gravitational constant M = mass of the mass R = distance from the center of the mass 'M'
How does Acceleration relate to gravity?
Not at all. However Gravity can impart an acceleration - Gravitational acceleration.
Can you calculate gravitational acceleration witn only having the time and the mass of the object?
Gravitational acceleration is always g = 9.8
How do I find the distance an object is from the earth with only it's mass and weight in it's current position?
You divide the mass by the weight, to get the gravitational acceleration. Then you use the fact that this gravitational acceleration, or gravitational field, is inversely proportional to the square of the distance. The distance should be calculated from the center of the Earth.
Can gravitational acceleration be reduced artificially?
No. Gravitational Acceleration is a constant and is a function of mass. The effects of the constant upon another mass can be altered but the acceleration itself will remain the same.
What three measurements do you multiply together to find gravitational potential energy?
Mass, acceleration of gravity, and height
What would you use to find the acceleration?
The answer depends on the context: You can find the acceleration if you know any three of : initial velocity, final velocity, time, distance travelled. You can find it if you know the mass and force. You know the two masses and the distance between them (gravitational acceleration).
How to find out weight of the person in the moon if we know the mass in the earth?
weight= mass x gravitational acceleration. thus if you know the mass and knew that the gravitational acceleration of the moon is 1/6 of that of the earth it is an easy calculation to get the objects lunar weight.
What is the relation connecting acceleration and gravitational force?
The same as the relation between acceleration and any other force. Force = (mass) x (acceleration) If the force happens to be gravitational, then the acceleration is down, and the formula tells you the size of the acceleration. If the acceleration is down and there are no rocket engines strapped to the object, then it's a pretty safe bet that the force is gravitational, and the formula tells you the size of the force.
