In a curtain collapse, what happens to materials?

• A. Materials Fall Straight Down
• B. Materials Fall Outward
• C. Materials Explode Upward
• D. Materials Bend Downward

Answer: (A)

When a curtain-style barrier fails, gravity pulls the hanging fabric downward. Curtains are lightweight and flexible, not rigidly braced to push material outward or upward. Once support is lost, the mass simply drops toward the floor, so the debris falls straight down rather than outward, upward, or bending away. This vertical drop is the typical behavior you’d expect in a curtain collapse.
