  Mechanical Energy The energyan object has from its motion or its potential for motion.

  1. Potential energy. Theenergy an object has as a result of its position or ability to perform work. A stretched rubber band, compressed air, or a rock sitting on the top of a cliff all have potential energy. 2. Kinetic energy. The energy specifically associated with an object’s motion. A bicycle or skateboard in motion possesses this form of mechanical energy. Mechanical Energy

  Energy in matterdue to arrangements of its parts, its composition, location and structure. It is commonly considered as a stored energy having the potential to do mechanical work. 1. Gravitational Potential Energy (GPE). Energy stored in an object’s position. 2. Chemical Energy. Energy contained inside substances. 3. Elastic Energy. Energy contained in an stretched object. 4. Electrical Energy. Energy from the movement of electrically charged particles. 5. Nuclear Energy. Energy obtained from the Fusion and Fission of Nuclei of atoms.

  Transformation of Energy •LAWOF CONSERVATION OF ENERGY •Definition: This states that energy can change from one form to another, but it cannot be created or destroyed. •Important: When energy is used, it does not disappear……it simply changes to another form.
