gravity varies with altitude and latitude. interesting that they have they are anagrams of each other.
9.8 m/s2 on earth
Fg = G m1 m2 / d2
WOW! |

So far, we know that charge is a property of all matter, whether it be a positive, negative, or neutral overall charge. We also know that charge is responsible for all electrical and magnetic forces and interactions.
But what is the electric force?

Quite Simply, action = reaction.
In more sophisticated terms:
For every action force, there is a reaction force which is equal in magnitude and opposite in direction.

Here's the link to the article I mentioned this morning. I don't know how legit this is, I haven't looked for any other sources, but I found it interesting nonetheless. http://www.pinktentacle.com/2008/12/scientists-extract-images-directly-from-brain/ What's your take? Is this completely incredible, or horribly terrifying? |

From Newton's first law, and by analysing the inertia of an object, what must we do to accelerate an object?
Apply a force!
What if the object is really, really massive?
