motion, forces, and energy

motion forces and energy : In general, the word energy refers to a concept that can be paraphrased as "the potential for causing changes", and therefore one can say that energy is the cause of any change. See also: Matter & Energy Energy Technology Nuclear Energy Physics Petroleum Thermodynamics Solar Energy The most common definition of energy is the work that a certain force (gravitational, electromagnetic, etc) can do. Due to a variety of forces, energy has many different forms (gravitational, electric, heat, etc.) that can be grouped into two major categories: kinetic energy and potential energy. According to this definition, energy has the same units as work; a force applied through a distance. The SI unit of energy, the joule, equals one newton applied through one meter, for example. Energy has no direction in space, and is therefore considered a scalar quantity. Energy is a conserved quantity, meaning that it cannot be created or destroyed, but only converted from one form into another. Thus, the total en....   More from Science Daily

  is Howard G. Yu I'm the inventor of the Yu Oscillating Generator. My invention produces more energy out then it uses in. Which is global patent pending. How it works is by harnessing the gravity potential energy and kinetic energy. You would get a mechanical gain to torque for a period of time while it oscillate side to side. As it slows due to resistance. An actuator kicker will enter force at the top of the mast to drive the device. Making up for any loss do to resistance. The invention ...

  laws is violated. Second, since gravity is already available (like wind) as an input force field (creating a fictitious force on any mass), there is no energy conservation law violation either. The main difference between wind and gravitation is: Wind power is generated by convection; transforming kinetic energy of the flowing air mass (due to natural temperature and pressure difference) to mechanical energy. On the other hand, gravitation (gravity when planet is alone) is like a ...

Question : Please, someone just give me as many fun facts on each of those. I really need two fun/interesting facts for each one, and even one is appreciated!

Answer : motion-the kinetic energy of a moving body is calculated by multiplying the mass by one half, times the square of the velovity forces-force is measured in newton-meters per square second energy-energy can neither be created nor be destroyed chemistry-table salt is created by the ionic bonding of sodium and chlorine..   More from Yahoo Answers
