ENERGY IS CONSERVE The law of conservation of mechanical energy states: Energy cannot be created or destroyed, only transformed! Energy Before Energy After PE Am I moving? If yes, Ko Am I moving? If yes, KE Am I above the ground? If yes, U Am I above the ground? If yes, U
Conservation of energy and conservation of mechanical energy Conservation of energy means conservation of all forms of energy together. Accounting all forms of energy within an isolated system the total energy remains constant. While mechanical energy accounts only two forms of energy namely kinetic energy K and potential energy U. If only conservative forces act on a system then total mechanical energy of the system remains constant l.e. K+U= cons tant Therefore, K + U = 0
Suppose you throw a ball upward What does work while it is flying through the air? Is the CHANGE in kinetic energy POSITIVE or NEGATIVE? Is the CHANGE in potential energy POSITIVE or NEGATIVE?
What does work while it is flying through the air? AKE GRAVITY (KE-KE .) = PE-PE Is the CHANGE in kinetic energy POSITIVE or NEGATIVE? NEGATIVE Is the CHANGE in potential energy POSITIVE or NEGATIVE? VEory Energy Beloe- Energy Energy Before Energy After POSITIVE
Conservation of Energy potential energy potential energy kinetic energy potential energy + kinetic
Energy consistently changes PE = KE- ME =- 3 PE = KE = PE = 1 m ME =-
