Why Does a Feather Fall More Slowly than a Coin?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why does a feather fall more slowly than a coin?

The Big Idea

Drop a feather and a coin. The feather drifts, the coin zooms. Why is one so much slower?

Air Pushes Up

Step one: air pushes up. Air pushes up on everything that falls. That upward push is called air resistance, or drag.

Shape and Weight

Step two: shape and weight. A feather is light and wide, so the air resistance is large compared with its weight, and it drifts down slowly. A coin is dense and compact, so it drops fast.

No Air

Step three: no air, same speed. In a place with no air, such as a vacuum chamber or the Moon, they fall at the same speed. An astronaut showed this on the Moon in nineteen seventy-one.

A Closer Look

Let's take a closer look! Air pushes up on falling things. A feather feels lots of drag. A coin cuts through air. With no air, they match.

Quick Facts

Quick facts! In a vacuum or on the Moon, a feather and a coin fall at the same speed. An astronaut showed this on the Moon in nineteen seventy-one with a hammer and a feather. A feather is light and wide, so air resistance is large compared with its weight. A coin is dense and compact, so it drops fast.

Think Like a Scientist

Now, think like a scientist! Drop a flat sheet of paper and a paper ball from the same height. Which lands first? Ask why the shapes matter. Try it again to check your result. Write what you notice, and share it with a grown-up.

Outro

A feather falls more slowly than a coin because air resistance is large compared with its light weight, but without air they fall together, as the Moon test showed. Science is amazing! Stay curious!
