Potential energy

• 1. The energy transferred to an object is stored as potential energy if it is not use to cause a change in the velocity or

  speed of the object.
• The potential energy possessed by an object is the energy present in it by virtue of its position or configuration
• Potential energy of an object at a height

  The energy present in an object that has been raised through a height, due to the work done against gravity
• How potential energy of an object at a height is defined

  1. Object is raised from the ground to a point above the ground

  2. Work is done against gravity in raising the object

  3. The gravitational potential energy is the work done in raising the object
• The potential energy of an object at a height depends on the ground level or the zero level you choose
• An object in a given position can have a certain potential energy with respect to one level and a different value of potential energy with respect to another level
• Energy cannot be created nor destroyed, only transformed from one form to another
• Potential energy can be converted into kinetic energy
