A value that describes how heavy an object is and is related to the force of gravity is
2 answers:
The heaviness of an object with the relation to force of gravity, is described by the ‘weight’
<u>Explanation: </u>
The heaviness of the object is referred to the mass of the object. When the mass of the object is concerned it is taken in space or vacuum where force of gravity do not exist.
Therefore, to value the actual heaviness of the object, mass is multiplied by the component of force of gravity, is termed as weight.

The free-body diagram of the forces acting on the flag is in the picture in attachment.
We have: the weight, downward, with magnitude
the force of the wind F, acting horizontally, with intensity
and the tension T of the rope. To write the conditions of equilibrium, we must decompose T on both x- and y-axis (x-axis is taken horizontally whil y-axis is taken vertically):
By dividing the second equation by the first one, we get
From which we find
which is the angle of the rope with respect to the horizontal.
By replacing this value into the first equation, we can also find the tension of the rope:
