Question

question 8 of 10
a leaf falls from a tree. because the leaf is so light, it will be affected by air resistance. taking this into account, what is the acceleration of the leaf as it falls?
a. 0 m/s²
b. less than 9.8 m/s²
c. exactly 9.8 m/s²
d. more than 9.8 m/s²

Explanation:

On Earth, the acceleration of free - fall without air resistance is approximately 9.8 m/s². When air resistance acts on a falling object like a light leaf, it opposes the motion and reduces the net force acting on the leaf. According to Newton's second law $F = ma$, a reduced net force leads to a reduced acceleration.

Answer:

B. Less than 9.8 m/s²
