define weight class 9 physics
Answers
Answer:
It is the measure of the force of gravity acting on a body,
The formula for weight it is given by:
w = mg
As weight is a force its SI unit is also the same as that of force, SI unit of weight is Newton (N). Looking at the expression of weight we see that it depends on mass and the acceleration due to gravity, the mass may not change but acceleration due to gravity does change from place to place, to understand this concept let’s take this example,
Shape of the earth is not completely spherical, but a oblate spheroid, therefore a person standing at the equator is far away from the center of the earth than a person standing at the north pole, as acceleration due to gravity is proportional to the inverse of square of the distance between two objects, a person standing at the north pole would experience more weight as he is closer to the center of the earth than a person standing at the equator.
