Science Mechanical Energy

• Energy


  Measure of the capacity to do work
• Mechanical Energy


  Energy of particle due to its motion and position
• Types of Mechanical Energy

  • Kinetic Energy
  • Potential Energy
• Kinetic Energy


  Energy of bodies in motion
• Potential Energy


  Stored energy
• Ball on top

  1. Has Potential Energy

  2. Potential Energy converted to Kinetic Energy

  3. No more Potential Energy, only Kinetic Energy
• Doubled Mass


  Doubled Kinetic Energy
• Doubled Velocity


  Four Kinetic Energy
• Doubled Mass


  GPE will be doubled
• Gravitational Potential Energy (GPE)


  Energy possessed by an object due to its position or location. The higher the position of the object, the higher the GPE.
• Elastic Potential Energy (EPE)

  Anything that can act like a spring, or a rubber band can have elastic potential energy.
• Chemical Potential Energy (CPE)


  A chemical bond can be thought of as an attractive force between atoms
• Loss of Kinetic Energy


  Gain of Potential Energy
• The sum of Kinetic Energy and Potential Energy is equal (energy was just converted)
• The energy stored within an object is called potential energy.
• Potential energy can be transferred to kinetic energy when the object moves or falls, resulting in motion.
• Kinetic energy is the energy possessed by moving objects due to their mass and velocity.
