Explanation :
The weight of an object is defined as the force that is exerted due to the gravitational force.
Mathematically, it can be written as :
W = m g
Where
m is the mass of the object
g is the acceleration due to gravity
Also,

We know that the value of g varies with respect to the location. At equator the value of g is less as compared to the poles.
The feature of an object that affects its weight are :
- Mass of the object
- Location of the object
- How much force Earth exerts on the object
