ENERGY CONSERVATION PRINCIPLE!

  • ENERGY CAN NOT BE CREATED OR DESTROYED,ONLY TRANSFORMED.

There are numerous equations linked together to discover different variable related to energy being transformed 
Equations:
  • (position)E=(position)P
  • a=(postion)velocity/(position)time
  • P(momentum)=mass x velocity
  • power=work/time = force x velocity
  • work=force x distance x cos
-> and of course Potential energy=mgh and Kinetic energy=1/2xmxv(squared)
Such graphs that could represent the changes in such equations would appear as so:



The Right Handed graphing system is common in physics allowing people to understand notation convections in 3 dimensional figures on a two dimensional surface. In physics the x axis is represented as the axis ,if in three dimension, would come off of the paper, the y represents the horizontal and the x vertical axis. Such as:




Recently a new spacecraft named Kepler has been launched in search of extraterrestrial life as well as habitable planets other than the only one we know of, Earth! Nasa keeps a missions log for Kepler with the latest updates on such discoveries.
