If you weigh 100 kilograms on earth, would your mass be 100 kilograms too (on earth)?

No...mass and weight are two different things. You would weigh 100 kilograms, but you can't take up room of 100 kilograms. It is not possible.

it is because acrylic blanket have acrylic textile fiber

explanation:

its is better than wool blanket

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
