What causes gravitational pull?
Editor s Note: We asked several scientists from various fields what they thought were the greatest mysteries today, and then we added a few that were on our minds, too. This article is one of 15 in LiveScience s Greatest Mysteries series running each weekday. In the deepest depths of space, gravity…
Equations for gravitational field
You told us how an almost churchlike atmosphere is pervading your desolate house now. And justifiably so, for unusual divine powers are at work in there. Besso to Einstein, The basis of Einstein s general theory of relativity is the audacious idea that not only do the metrical relations of spacetime…
Famous scientific laws
As long as we re talking about one of the greatest scientists who ever lived, let s move on to Newton s other famous laws. His three laws of motion form an essential component of modern physics. And like many scientific laws, they re rather elegant in their simplicity. The first of the three laws states…

Physics gravitational constant
In 1665, Isaac Newton recognized that all matter attracts all other matter, but he also recognized that the gravitational attraction of everyday objects for each other was far too small to be measured in his time. Newton tested his theory of gravitation with the large masses of astronomical objects like…
Gravitational force equation Physics
When you drop an object from some height above the ground, it has an initial velocity of zero. Simple equations allow you to calculate the velocity an object falls after a given period of time and the velocity it reaches at a given displacement. The equations assume that air resistance is negligible. Examples demonstrate applications of the equations. Questions you may have…

Define gravitational pull
Yet stick a girl on live telly, and it s as if the cameras exert some weird gravitational pull on her blouse.A star wobbles on its axis when orbiting bodies like planets exert gravitational pull (force of attraction between bodies of matter).The suggestion is the moon s gravitational pull affects the amniotic fluid in the same way it affects the water in the sea.The shipwreck…

Dark energy and Dark Matter
I ve been reading many clever answers here about dark matter and dark energy that called my attention to this question. Since Einstein s theory relates matter and energy as different states of the same thing, is it valid to think about dark matter and dark energy in the same way? Are they two states of the same dark thing ? Are they interchangeable? The short answer to your…

Define matter in science
Matter is everything around you. Atoms and molecules are all composed of matter. Matter is anything that has mass and takes up space. If you are new to the idea of mass, it is the amount of stuff in an object. We talk about the difference between mass and weight in another section. Matter is sometimes related to light and electromagnetic radiation. Even though matter can be…
