  2. 2. What is energy????? ● In physics, energy is one of the basic quantitative properties describing a physical system or object's state. Energy can be transformed (converted) among a number of forms that may each manifest and be measurable in differing ways. The law of conservation of energy states that the (total) energy of a system can increase or decrease only by transferring it in or out of the system Energy is measured in SI units of joules (J). Common types of energy transfer and transformation include processes such as heating a material, performing mechanical work on an object, generating or making use of electric energy, and many chemical reactions.
  3. 3. KINETIC ENERGY
  4. 4. Definition and formula ● In physics, the kinetic energy of an object is the energy which it possesses due to its motion.[1] It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body in decelerating from its current speed to a state of rest.
  5. 5. Potential energy ● ● In physics, potential energy is energy stored in a system of forcefully interacting physical entities .[1] The SI unit for measuring work and energy is the joule (symbol J). The term potential energy was introduced by the 19th century Scottish engineer and physicist William Rankine,[2][3] although it has links to Greek philosopher Aristotle's concept of potentiality. Potential energy is associated with forces that act on a body in a way that depends only on the body's position in space. These forces can be represented by vector at every point in space forming what is known as a vector field of forces, or a force field.
  6. 6. Total energy ● ● The total energy of a system can be calculated by simple addition when it is composed of multiple non-interacting parts or has multiple distinct forms of energy. Common energy forms include the kinetic energy of a moving object, the radiant energy carried by light and other electromagnetic radiation, and various types of potential energy such as gravitational and elastic. T.E = P.E.+ K.E = CONSTANT
  7. 7. CONSERVATION OF ENERGY At point 1 TE = PE + KE = mgh +1/2mv2 ( v2 = 0 ) TE = mgh At point 2 TE = mg(h-x) + ½ mv2 ( v2 = 2gx ) = mgh – mgx + 12 * 2mgx = mgh – mgx + mgx TE = mgh At point 3 = mgh +1/2mv2 ( h =0) ( v2 = 2gh ) = 1/2m * 2gh TE = mgh
