Distinguish between mass and weight of an object. How does the weight of an object change when moving from the equator to the poles? When can the weight of an object be zero?

(N/A) The distinction is shown in the table below:

Mass	Weight
$1.$ It is the amount of matter contained in a body.	$1.$ It is a force equal to the gravitational pull exerted by a planet.
$2.$ It is a constant quantity and does not change with respect to position or place.	$2.$ It is a variable quantity and changes with the change in acceleration due to gravity of a place.
$3.$ Mass of a body can never be zero.	$3.$ Weight of a body can be zero during free fall.
$4.$ It is measured by using a physical balance.	$4.$ It is measured by using a spring balance.
$5.$ It is a scalar quantity.	$5.$ It is a vector quantity.
$6.$ It is measured in kilograms $(kg)$.	$6.$ It is measured in newtons $(N)$.

When an object is moved from the equator to the poles, its weight increases because the acceleration due to gravity $(g)$ is greater at the poles than at the equator.
Weight of an object becomes zero at the center of the Earth or when a body is in a state of free fall.
