Why do We Feel Weightless in Space?

-
 
The Earth pulls everything downwards with a force known as gravity. It keeps objects on the Earth's surface and prevents them from floating away. It gives the objects, their weights. This gravitational pull gets weaker as we move away from the Earth.

  In space, the force of gravity has very little effect and so is the pull from other planets, since they are also far away. Without the force of gravity, objects in space do not have weight and hence are weightless.

Quantum Theory Full Documentary HD https://www.youtube.com/watch?v=A-iB5iEy2Kc&t=1183s quantum hypothesis Posted by: Margaret Rouse Contributor(s): Ivy Wigmore Quantum hypothesis is the hypothetical premise of current material science that clarifies the nature and conduct of issue and vitality on the nuclear and subatomic dimension. The nature and conduct of issue and vitality at that dimension is at times alluded to as quantum material science and quantum mechanics. In 1900, physicist Max Planck introduced his quantum hypothesis to the German Physical Society. Planck had tried to find the reason that radiation from a sparkling body changes in shading from red, to orange, and, at last, to blue as its temperature rises. He found that by making the suspicion that vitality existed in individual units similarly that issue does, instead of similarly as a steady electromagnetic wave - as had been once in the past accepted - and was consequently quantifiable, he could...

F latworms are flat, simple-bodied worm like animals ranging from the size Of a few millimetres to larger tropical forms. These worms are largely found in temperate and tropical regions of the world. They live under the stones and leaves , in freshwater streams and ponds. A few of them also live on land. Flatworms can regenerate themselves and if a worm is cut into few pieces , each piece will grow into a new flatworm. Some flatworms are parasites. For example the flukes and tapeworms.

What is a Meteorite?

Meteorites are bodies (a lump of stone or metal) from space that are large enough to reach the ground without burning up in the atmosphere. The largest known meteorite weighed about 60 tones and landed in Namibia , Southern Africa. Meteorites were probably formed at the same time as the Solar System. A falling meteorite leaves a brilliant trail in the sky known as a fireball. Some meteorites are mostly metal (iron and nickel ) while others are made of stone.
