Lesson 6?: Title: WORK
... The moon is orbiting the earth; is work being done on it? No. The centripetal force is d. This means that gravity will not change the speed (or Ek or Eg) of the moon. Note: we don’t look at Work for astronomical situations – we use gravitational energy formulae, and changes of momentum. Work-Ener ...

... SPEED is how rapidly an object moves or changes its position. It is calculated by dividing how far an object moves by the time taken to move. Speed = (distance moved) / (time taken moving) Example. If a runner covers 400m in 50 s, the average speed is 400m / 50 s = 8 m/s ACCELERATION is how rapidly ...

Alternative energy
Alternative energy is any energy source that is an alternative to fossil fuel. These alternatives are intended to address concerns about such fossil fuels.The nature of what constitutes an alternative energy source has changed considerably over time, as have controversies regarding energy use. Today, because of the variety of energy choices and differing goals of their advocates, defining some energy types as ""alternative"" is highly controversial.In a general sense, alternative energy as it is currently conceived, is that which is produced or recovered without the undesirable consequences inherent in fossil fuel use, particularly high carbon dioxide emissions (greenhouse gas), an important factor in global warming.
