The Penny Drop Myth: Why It's Not As Dangerous As You Think
Have you ever heard the saying, "A penny dropped from the Empire State Building can kill you?" It's a popular myth that has circulated for years, fueled by the idea that a small object falling from a great height could gain enough speed to become deadly.
While the thought of a penny plummeting from a skyscraper is certainly unsettling, the reality is much less dramatic. The truth is that a penny dropped from a building like the Empire State Building, while it might sting a bit, won't cause serious harm. Here's why:
The Science of Terminal Velocity
The key to understanding this myth lies in the concept of terminal velocity. Terminal velocity is the maximum speed an object can reach while falling through the air. It's determined by two main factors:
- Gravity: Gravity pulls the object downward, causing it to accelerate.
- Air Resistance: As the object falls, air resistance pushes back against it, slowing its acceleration. Eventually, the force of air resistance equals the force of gravity, and the object stops accelerating, reaching its terminal velocity.
A penny's small size and relatively flat shape create a lot of air resistance. This means its terminal velocity is significantly lower than you might imagine. In fact, a penny's terminal velocity is estimated to be around 50 miles per hour.
Myth Versus Reality
While 50 miles per hour might seem fast, it's not enough to cause serious harm. The force of impact from a penny dropped from a skyscraper would be similar to a light tap. It might sting or leave a small bruise, but it wouldn't be fatal.
The myth of the deadly penny is likely rooted in our fear of falling objects. We know that objects falling from great heights can be dangerous, and our brains tend to exaggerate the potential consequences. However, it's important to remember that the size and shape of an object, as well as its terminal velocity, play a crucial role in determining its impact.
The Real Dangers of Falling Objects
While a penny dropped from a skyscraper is unlikely to cause harm, falling objects in general can be very dangerous. Larger objects, such as bricks, tools, or even furniture, can reach much higher terminal velocities and cause serious injuries or even death. It's essential to be aware of your surroundings and take precautions to prevent falling objects.
Here are some tips to stay safe around falling objects:
- Look up when walking in urban areas: Be aware of your surroundings and watch out for potential falling objects.
- Secure loose objects: Make sure that any objects on balconies, rooftops, or windowsills are properly secured.
- Report loose objects: If you see a loose object that could potentially fall, report it to the appropriate authorities.
Remember, while the penny drop myth is just that, a myth, the dangers of falling objects are real. Stay safe and be aware of your surroundings!
