SCI - Lesson 3

• kinetic energy is the type of energy possessed by an object by virtue of its motion
• potential energy is the type of energy possessed by an object because of its position
• 4 types of potential energy:

  • gravitational energy
  • chemical energy
  • nuclear energy
  • mechanical energy
• 5 types of kinetic energy:

  • motion energy
  • heat energy
  • radiant energy
  • sound energy
  • electrical energy
• gravitational energy - an energy stored in an objects position
• chemical energy - energy stored in bonds of atoms and molecules
• nuclear energy - energy that holds the nucleus together and is stored in the nucleus of the atoms
• mechanical energy - objects by tension
• motion energy - energy stored in the movement of objects
• heat energy - energy due to vibration and movement of the atoms and molecules within substances
• radiant energy - electromagnetic energy that travels in the transverse waves
• sound energy - movement of energy through substances in longitudinal compression/rarefaction waves
• electrical energy - tiny charged particles called electrons, typically moving through a wire
• conversion or transformation of energy is a process a that involves energy change from one to another
• energy conversion in juggling - any object that rises or falls experiences a change in its kinetic and gravitational potential energy
• law of conservation of energy - states that energy is transformed from one form to another
• energy is neither created nor destroyed, thus it has always existed in one form to another
