Here you not only you can download the PDF with ease rather you can view online in case you are unable to download the PDF or your smartphone doesn’t have a PDF reader.
By the way, I not only uploaded the notes of the 4th chapter, rather of all the chapters of 9th Class Physics have been uploaded here on Top Study World.
Physics is the underlying science for much of technology, and so it is responsible for a large fraction of the wealth of the modern world. If you are reading this essay on a computer screen, that screen would not be possible without a century of physics research.
The computer in which it is displayed would not be possible either. The Internet through which you read this essay also relies on physics discoveries. If physics hadn’t been discovered when it was, some other field might have produced the same results, but we can’t be sure of that.
It’s not just that physics has produced things we like, like computers and medicine and lasers and nuclear power plants. Physics has also produced things we don’t like, like nuclear weapons and pollution from fossil fuels.
But if we had never developed physics, I suspect our lives would be less pleasant than they are now: poorer, shorter, more brutal, and more isolated from one another.
The idea that things fall because they’re attracted to the earth is an ancient one, but it wasn’t until Newton unified all of physics in a single grand design that anyone realized how simple gravity really was.
You might think that’s because Newton was the greatest genius who ever lived. But I wouldn’t be surprised if you think that. After all, Newton said it himself.
He called his theory “the greatest discovery that ever was made by man.” And there’s nothing like the prospect of making a great discovery to make you work hard on something.
But if Newton were alive today, I doubt he’d get funded to study gravity. If you told him you wanted to spend your career working on gravity, he’d think you were crazy.
