Question

Why do we use weight instead of mass

please give me exact answer​

Answer 1

Explanation:

Because they do not know the physics precisely. Mass is what stuff is made of. Weight is the gravitational force that the planet exerts an a given amount of mass at a give distance from the center of gravity of the planet. In a free falling reference system there is mass but no weight.

Answer 2

Answer:

weight = mass * acceleration due to gravity

since we are living on earth with has g = 9.8m/s²,

all the weighing machines will show our weight instead of mass.
