Nails fall at the same speed as feathers because of air resistance. In the absence of air resistance, all objects would fall at the same rate regardless of their mass. However, in the presence of air resistance, lighter objects like feathers experience more air resistance than heavier objects like nails, which balances out the effect of gravity and causes them to fall at the same speed. This phenomenon is known as the principle of equivalence. **

In a vacuum, feathers and iron balls would fall at the same speed due to the principle of gravitational acceleration. However, in the Earth's atmosphere, feathers experience more air resistance compared to iron balls, causing them to fall at different speeds. Feathers have a larger surface area relative to their mass, leading to greater air resistance, while iron balls are more aerodynamically shaped and experience less air resistance, allowing them to fall faster. **

The volume of 1 kg of bed feathers can vary depending on the type and density of the feathers. However, on average, 1 kg of bed feathers can occupy a volume of approximately 10-15 liters. This can be equivalent to the size of a large pillow or a small to medium-sized backpack. Feathers are lightweight and can be compressed, so the volume may vary based on how tightly they are packed. **

You can get bird feathers from a variety of sources such as craft stores, online retailers, or specialty shops that sell natural materials. Look for stores that specifically sell feathers for crafting or fly tying, as they are more likely to carry a variety of bird feathers. You can also consider reaching out to local bird sanctuaries or wildlife rehabilitation centers, as they may have feathers available for educational or crafting purposes. **
