According to the definition of the power (Energy), the scientist is the ability (Ability to do work), this behavior may be in the form of motion or change of an object. Energy breakdown by features 1. potential energy (Potential Energy) is the energy that occurs when an object is placed in a position where it can move either from gravity or magnetic force draws from such stones are placed on high edges. 2. kinetic energy (Kinetic Energy) is the energy that occurs when an object moves like a car running out from the bow rises the bike is moving, etc. 3. the cumulative energy (Stored Energy) is the energy stored in วสัดุ or such things as chemical energy stored in food. In the lump of coal The oil or timber, firewood, which the energy is stored in the form of chemical elements or materials, or anything of that, and will be released when the material or something of the such changes, such as the burning of wood, firewood, energy, heat, etc. Both potential energy and kinetic energy, mechanical energy that can transform plain give him/her to come back.Potential energy is accumulated in the object will change the climate movement. As kinetic energy is energy in motion, and objects that are based on the value of energy, mechanical energy conservation rules will be fixed. Therefore, the mechanical energy = kinetic energy + potential energy always.When the power in the system (mechanical energy) is probably the increase in potential energy. Kinetic energy is reduced, however, if. Potential energy decreased. Kinetic energy increases.The more potential energy that is found has two types. 1. the gravity potential energy Caused by the energy accumulated into an object that is higher up.The accumulated energy is stated in an upon us to make it a higher level than before. Like lifting rocks up above, the potential energy increases.(Ep = mgh when Ep is potential energy m is the mass of the object, g is the acceleration due to Earth's gravity, and h is height).When leaving the rocks down potential energy to kinetic energy is changed by adding more speed (Ek = 1/2 m v ^ 2 when Ek is the kinetic energy.M is the mass of the object and v is the velocity of the object), so when we lift the object will fall through the floor too strong when low. 2. elastic potential energy like we pull spring balances more pulling force from the very length of the spring away from the balance, the more.(Potential energy) (Ep =-kx when Ep is the potential energy of the spring constant is k is the spring or the Shin and x is distance themselves stretched).
