How is weight related to gravity?
Answers
Answer:
Weight is directly related to gravity because, when weight increases gravity also increases.
To understand it clearly, we have to take a cricket ball of 1kg and one of 4kg.
First throw a ball of 1kg in the upward direction, then we see that the ball goes into certain height and after it comes towards the earth in a certain speed.
Again throwing a ball of 4kg in the upward direction, then we see that this ball cannot go more in the upward direction as the first ball goes but it comes more faster than the first ball towards the earth.
By this we can clearly understand that when weight increases gravity also increases.
Answer:
Explanation:
Any two bodies with a mass are attracted towards each other by a force directly proportional to the product of their individual mass and inversely proportional to the square of the distance separating them.
The exact force with which two bodies with mass M1 and M2 and separated by a distance R is given by F = G*M1*M2/R^2 where G is the gravitational constant and equal to 6.674*10^-11 N*m^2/kg^2.
The weight of an object on any other object refers to the gravitational force of attraction between the two. This is expressed in terms of Newton. Mass on the other hand is expressed in terms of kilograms. For example an object with a mass of 1 kg has a weight of 9.8 N on the surface of the Earth. If the object were placed on another planet its mass would continue to remain the same while its weight would vary with the mass of the planet and its radius.
