Car Railroad

Why was the wheel a great invention? Physics?

Why was the wheel a great invention?

One way to answer a question like this is to consider what the world would be like without wheels.

No cars, railroads, bicycles, roller skates, tractors, gears, pulleys just to name a few. I'm sure you can think of many other inventions that rely on wheels. Just think of all of the inventions that wouldn't exist without the wheel. So how would the world be different without these things? That is the answer to why the wheel is a great invention.

For example, imagine the implications of farming without tractors. Could the current population survive based on farming using manual methods? You get the idea.. :)

Hope this helps,
