Few people are surprised by the fact that an asteroid, the size of Mt. Everest, could do a lot of damage when it hits the Earth. And it is not really surprising that such bodies are out there; every few years, there is a newspaper headline about a "near miss" in which an object misses the Earth by "only a few million miles." But why should an asteroid impact cause an explosion? It was made of rock, not dynamite. And why such a big explosion? But then, what is an explosion, after all?
We all know that golf isnt the most fun sport in the world but what this video reveals is the components that make up the physics of the sport and surprisingly it is very interesting. First off, i want to give a little information about the mechanics of golf, for example, a backspin imparted on a golf ball will cause the ball to gain loft and stay in the air longer. As the ball spins in the air, it directs more airflow up over the top of it and then downward behind it.
This means that the ai
Although a bit lengthly the significance of this video takes a tour of the life and death of starts and what they have to offer in the universe. Also, some facts about stars include that it is large celestial body composed of gravitationally contained hot gases emitting electromagnetic radiation, especially light, as a result of nuclear reactions inside the star.
Stars are wondrous things that we know little about because of our limitations in t
