Question
Explain why the feather reaches the ground after the hammer
Solution
The reason why a feather reaches the ground after a hammer when dropped from the same height is due to air resistance. Here's a step-by-step explanation:
-
Gravity: Both the feather and the hammer are subject to the same gravitational force, which pulls them towards the ground.
-
Air Resistance: However, the feather experiences a greater air resistance than the hammer. This is because of its shape and light weight. The feather's large surface area in relation to its weight increases the effect of air resistance on it.
-
Velocity: Due to the greater air resistance, the feather falls slower than the hammer. The hammer, being heavier and more compact, can break through the air more easily and thus falls faster.
-
Impact: As a result, the hammer reaches the ground first, followed by the feather.
Note: In a vacuum, where there is no air resistance, a feather and a hammer would fall at the same rate. This was famously demonstrated by astronaut David Scott on the moon in 1971.
