Question

Two objects fall from an apartment window sill at the same time. Object 1 lands on the sidewalk in 3.6 seconds. Object 2 lands on the sidewalk in 3.3 seconds. What can be concluded about the objects? (1 point)
• Object 1 has more surface area than Object 2.
• Object 2 has more mass than Object 1.
• Object 1 has less surface area than Object 2.
• Object 2 weighs less than Object 1.

Answer 1

Object 1 has more surface area than Object 2.

Reason: Object 1 takes longer to reach the ground, so it experienced greater air resistance (drag). Greater surface area produces more drag and slows the fall. You cannot conclude the masses (weights) from the times alone.
