Question

a parachute works because the canvas of the parachute is acted upon by _______.
a. air resistance
b. gravity
c. velocity
d. momentum

please select the best answer from the choices provided.
○ a
○ b
○ c
○ d

Explanation:

A parachute functions by utilizing air resistance. When a parachute opens, the large surface area of the canvas interacts with the air, creating a significant upward force (air resistance) that opposes the downward force of gravity, slowing the descent. Gravity (B) is the force pulling down, velocity (C) is speed with direction, and momentum (D) is mass times velocity—none of these explain how the parachute works to slow down; air resistance is the key force here.

Answer:

A. air resistance
