Explain the properties of weight in detail note?

Weight is the product of mass multiplied by acceleration acting on that mass. Usually, it's an object's mass multiplied by acceleration due to gravity. On Earth, mass and weight have the same value and units. However, weight has a magnitude, like mass, plus a direction.

The weight of an object is the force of gravity on the object and may be defined as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton. Density is mass/volume.

It is the measure of the force of gravity acting on a body.

The formula for weight is given:

w = mg

As weight is a force its SI unit is also the same as that of force, the SI unit of weight is Newton (N). Looking at the expression of weight we see that it depends on mass and acceleration due to gravity, the mass may not change but the acceleration due to gravity does change from place to place. To understand this concept let’s take this example,

The shape of the earth is not completely spherical, but an 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 the 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.

The material properties are size, shape, the density of the particles, and their intrinsic mechanical properties (Young's modulus, yield stress, fracture toughness, etc.

Weight depends on the effect of gravity. Weight increases or decreases with higher or lower gravity.

Weight can be zero if no gravity acts upon an object, as in space.

Weight varies according to location.

Weight is a vector quantity. It has magnitude and is directed toward the center of the Earth or other gravity well.

Weight is measured using a spring balance.

Weight often is measured in newtons, a unit of force.
