a book and a piece of paper, the same size, fall at different rates. how can you change the shape of the paper so it will fall at nearly the same rate as the book? explain your answer.

a book and a piece of paper, the same size, fall at different rates. how can you change the shape of the paper so it will fall at nearly the same rate as the book? explain your answer.

Answer

Brief Explanations:

The different fall - rates are due to air resistance. By crumpling the paper, we reduce the air - resistance it experiences. Air resistance acts against the motion of an object falling through the air. A flat piece of paper has a large surface area and thus more air resistance, while a crumpled paper has less surface area exposed to air, similar to a book which has less air - resistance relative to its mass. So, by crumpling the paper, we make the air - resistance on it similar to that on the book in proportion to their masses, making them fall at nearly the same rate.

Answer:

Crumpling the paper reduces its surface area exposed to air, decreasing air resistance so it falls at nearly the same rate as the book.
