How can you calculate the amount of gravity something has?

Answer 1

Tossing a ball up repeatedly will do the trick. It will fall. You can catch it when it comes down and toss it back up. It won't not come back down. Gravity has a firm hold on it, and it won't let go.

Answer 2

Gravity has never been detected. It remains one of the mysteries of physics because no wave or particle has ever been detected, but all indications are that it must exist. One of the reasons that is is not detectable is because it is like a quiet pond where all the water is still, because everything is in such close balance in the Universe. If you drop a pebble in the pond, you will see the pebble and the ripples. Scientists have not yet been able to see a 'pebble' or 'ripple' in the pond that is called the force of gravity; one of the four basic forces in the universe along with the weak force, the strong force, and the electromagnetic force. ya know what, i think you can detect it. hold up an apple and let go. if it falls, there is gravity

Answer 3

Gravity is always measured in interaction between two masses, for it must act between two masses (it pulls two objects together). If you only have one object, there is no gravitational force. You will see why if you put a 0 as one of the two masses in the formula.

The formula for calculating gravitational force is:

F = G(m1m2) / r2

- G is the gravitational constant, a very small number representing the strength of gravity; as far as we know, this should always be 6.67 * 10-11 in anything you are calculating.

- r is the distance between the centres of the masses.

- m1 is the mass (in kilograms) of the first object, and m2 is the mass of the second.

This will give you F, the force of gravity in Newtons.

Here's what you would do with calculating the gravity between a 100kg object on Earth and the Earth itself:

G = 6.67 * 10-11

m1 (this will be the 100kg person) = 100kg

m2 (earth, of course) = 5.97219 * 1024

r (pretty much the radius of Earth; we can consider this object on the surface) = 6,378,137 meters

Now:

F = 6.67*10-11(100 * 5.97219*1024) / 63711372

Throw that into a calculator and get:

9.81353687175 N

Answer 4

Gravity is dependent on mass and distance between objects. The formula for calculating the force of gravity between two objects is F = (G * m1 * m2) / r^2, where G is the gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between their centers. The greater the mass and the smaller the distance between objects, the stronger the gravitational force.

Answer 5

Drop a wright from a height s and measure the time to fall t, s= 1/2 gt2.

Gravity is then measured by g= 2s/t2.
