the measure of the force of gravity acting on object is called?

Answer 1

your "weight" is measured in newtons. gravity in itself is not a force however.
weight is calculated by the equation W=mass x (acceleration due to gravity)

so for a 70kg person at the earth's surface it would be:
W = 70 x 9.81
=686.7N of force acting on the object

Answer 2

The force of gravity is measured as an acceleration on the planet earth at sea level this force is called 1 G and it has been measured at 9.8 m/sec or 32 ft/sec.

Gravity is measured in distance per unit of time like feet per second.

According to Wikipedia: http://en.wikipedia.org/wiki/Newton
"A newton is the amount of force required to accelerate a body with a mass of one kilogram at a rate of one meter per second squared. Algebraically, N = kg•m/s²."

So you measure gravity in Gs, feet or meters per second AND newtons.

The answer is NOT mass because mass is constant, the size of the object that the mass is resting on can vary so the force of gravity can vary. On earth and under 1G we say that the mass = weight which would be pounds or kilograms. But a force is an action working on an object over time therefore the correct answer is Newtons, mass is only part of the equation.

Answer 3

Ignore the ones saying 'mass' - the answer is weight. This is why your mass remains the same when you are on the moon (you still have the same volume and density) but your WEIGHT is lower since gravity's pull is lesser on the moon.

The answer is 'weight'. MASS IS NOT CORRECT.

So, next time someone asks you how much you WEIGH, you can respond '870 Newtons'. Your mass may be 87 kg, but your weight is measured in units of force, hence Newtons.

Answer 4

Force is measured in Newtons (N)
N = kg*m/s^2

On Earth's surface, an object's "gravitational force" can be approximated by 9.8 times the object's mass in kilograms. For example, a 2kg rock will have 19.6N of gravitational force acting on it.

The equation for general gravitational force is:
F = G*M*m/r^2
where G is the gravitational constant = 6.673x10^-11, M is the mass of object 1, and m is the mass of object 2.
r is the distance between their centers of mass.
This equation holds true for objects ranging in mass from hydrogen nuclei to red giant stars.

You can use Newton's F=m*a law to cancel out one of the masses in the gravitational force equation, resulting in a "gravity constant" for a given radius. Plugging in the mass and radius of the earth as constants, you end up with
a = 9.80665, which is where we get our 9.8 approximation from.

Answer 5

"g"s I think. The Earth exerts a force of 1g. But I'm no physics expert.

Answer 6

The answer is Mass

Answer 7

I am 100% positive that the answer is mass

Answer 8

weight
