It is an approximate average value for acceleration due to gravity on the surface of the earth. It is affected by altitude, the density of the material near the surface from place to place. And of course, it is totally useless in space, on the moon or Mars.

How do you measure force with a rubber band?
A rubber band will , approximately, stretch an amount "x" in direct proportion to the force "F" applied to it. So you can write this as an equation, F = KX . To find the proportionality constant "K" , hang a known weight "W" from the rubber band and measure the stretch "L". then divide W/L = K . This is called "calibrating" the rubber band.
What is the weight of an seventeen year old?
The average weight of a seventeen year old varies greatly with gender and height, and those two elements are crucial in determining the average weight.
Does the weight of the body remains constant everywhere in the universe?
no it does not remain contant.
What is the formula used to calculate the weight of an object if you are given the mass in kilograms?
Mass is a property of matter and is therefore a constant. Weight however can change, it is the force exerted by that mass in a gravity field. Thus in different gravity fields a constant mass will weigh differently. Weight = Mass * the acceleration of gravity.
Does mass remain constant?
Yes, Mass remains constant because the definition of mass does not mean weight. Mass means the amount of room and object takes.
What are difference between constant immersion hydrometer and constant weight hydrometers?
Constant immersion hydrometers are designed to be fully submerged in the liquid being tested, providing readings based on the buoyancy principle. Constant weight hydrometers are initially weighed in air and then in the liquid, with the difference in weight determining the liquid density. Constant immersion hydrometers are typically more accurate for measuring specific gravity, while constant weight hydrometers can be more convenient for quick measurements.
What do you measure when determining weight that you don't measure when determining mass?
The effect of gravity is measured.
What is the pony club weight restriction?
I don't think there is a weight restriction, because some ponies may be overweight, but in order to be classified as a pony, a Horse must be 14.2 hands or under when fully matured.
Is there weight restrictions for a NASCAR driver?
There is no weight restriction on the driver. There is a minimum weight for the car which is 3450 pounds.
What does it mean to say mass and weight are porportional to each other?
Saying mass and weight are proportional means that as an object's mass increases, its weight (the force of gravity acting on it) also increases in direct proportion. This relationship is governed by the equation F = ma, where F is the force (weight), m is the mass, and a is the acceleration due to gravity.
What is a blance scale used for?
Determining the weight of something.
What requires commanders to weight the military advantage anticipated by an attack on a military objective against the harm caused to civilians or civilian property?
proportionality
Can you take a 55 inches tv on the airplane?
Yes, as long as it does not exceed the weight restriction.
What is the formula for calculating weight when you know the mass?
Weight = Mass x (Local Gravitational Constant)/(Standard Gravitational COnstant)
What will the weight of a ball in water be if its weight in air is 2 newtons?
Weight in a constant gravitational field is also constant, regardless of any surroundings. The weight will be two newtons underwater as well.
Why is constant weight important?
Constant weight is important in scientific experiments to ensure that any change in measurements or observations is due to the variables being tested and not due to changes in weight. Maintaining a constant weight helps to minimize potential sources of error and increases the accuracy and reliability of the experimental results.
How do you use the word weight in a sentence?
The great weight of a blue whale is balanced by its buoyancy in the water. His shoulders seemed to sag under the weight of his responsibilities. The heavy weight was being used as a makeshift doorstop.
