Question

The weight of a body varies from place to place why ?​

Answer 1

Gravity has a major influence on weight, which causes it to vary widely from place to place.

Reason:

Weight = mass x gravity

• Remember that mass is a constant everywhere.
• Gravity varies, therefore weight does too.
• Meaning that a body won't weigh the same across the surface of the earth.

The following factors may be in charge of weight variation:

• The earth's shape is an oblate spheroid, which means that its surface doesn't have a constant radius.
• Due to this, some locations are closer to the earth's center than others (such as the poles), and vice versa (the equator).
• In accordance with Newton's law of universal gravitation, an object's weight is inversely proportional to its mean distance squared (also called inverse square law).
• Because of this, an object put close to the equator will weigh less than an identical thing positioned closer to the pole.
• The earth's rotation, altitude, and regional topography are other factors that affect weight distribution across the surface of the planet.

The weight of an object is a measurement of the gravitational force acting on it or the force necessary to support it, whereas mass is a measure of the thing's inertial attribute or we may describe it as the quantity of matter an object contains.
