The common understanding associated with gravity is limited to its relation to the ground beneath our feet. Gravity wants to draw us toward the Earth (a force we experience as our weight) and the Earth to us; however, Earth’s massive size makes its movement towards us imperceptible, i.e....
If earthquake happened, firstly, don’t panic and calm down. Secondly, find some safe place to stay and don‘t run in such a hurry. If in the room, one should hide himself/herself under something hard, such as desk, table or even bed and keep away from shelf and cupboard, and never...

life here on Earth, but a prerequisite for it. However, since human beings seem intent on getting off this rock – escaping the “surly bonds of Earth”, as it were – understanding Earth’s gravity and what it takes to escape it is necessary. So just how strong is Earth’s gravity?

The term ‘single-use plastic’ is kind of self-explanatory, but in case you’ve been living under a rock, it refers to an item made of plastic, which is used once before it is thrown away. If you’ve been living under an even bigger rock, these plastics are polluting our earth mor...
Once aloft, gravity (the weight of the hang glider and pilot) pulls the glider back toward Earth and propels the glider forward, continually causing air to flow over the wing. In addition to the horizontal movement of air, hang gliders can get lift from rising currents of air, such as ...
Plants still need all the basics they receive on Earth -- water, carbon dioxide and nutrients. Though plants can live with little gravity, it's best for them to have at least a small amount to prevent any growth problems. Artificial gravity, produced by a mechanical centrifuge, helps solve...
