What Is The Measure Of The Force Of Gravity On An Object?
Answers
Answer:
your answer is here !
Explanation:
Force is the vector product of mass and acceleration: F = ma. Weight is a special case of that formula, where you substitute the acceleration of gravity, g, for a. We can therefore write: W = mg.1
For example, if an object has a mass of 10 slugs2, its weight near the surface of the Earth is 10 x 32.2 (ft/s2) = 322 pounds (pound-force).
If an object has a mass of 10 kilograms, its weight near the surface of the Earth is 10 x 9.8 (m/s2) = 98 newtons.
You can measure the force of gravity on an object (i.e., its weight) by putting it on a scale.
follow me !
The force of gravity on an object is called weight and is measured in pounds in English units and in newtons in metric units, where 1 pound = 4.44822 newtons.
The unit of pounds is used in two ways, as a force (or weight), and as a mass, where 1 pound-mass gives a weight of 1 pound-force.
