an object?
anyone can help me don't post shame less comment please give answer me fast

Answer:
As Force is directly proportional to the mass of each object, the force will be doubled. 2) d is doubled, Force will become 1/4th as Force is inversely proportional to the square of distance. d is tripled.
The most important part about this is not only that objects pull on each other, but that two objects attract each other with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between them. This is known as Newton's law of universal gravitation.
The Acceleration of Gravity. It was learned in the previous part of this lesson that a free-falling object is an object that is falling under the sole influence of gravity. A free-falling object has an acceleration of 9.8 m/s/s, downward (on Earth).
Gravitational force between the Earth and an object is known as Earth's gravity or weight of the object. ... The weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton.
Answer:
Explanation:
1. NO
2. NO
3. NO
7. UNIVERSAL GRAVITATION LAW IS IMPORTANT BECAUSE GRAVITATION IS THAT MUCH IMPORTANT TO ALL LIVING AND NON-LIVING ORGANISMS ITS ABOUT HOW THE THINGS ARE ATTRACTED EACH OTHER THE FORCE OF ATTRACTION IS CALLED AS FORCE OF ATTRACTION
