Key Concepts Covered

➡️ Energy conservation – The principle that energy cannot be created or destroyed in an isolated system, only transformed
➡️ Mechanical energy – The energy possessed by an object due to its motion and position
➡️ Friction and non-conservative forces – Forces that dissipate mechanical energy as heat and sound
➡️ Energy dissipation – The process through which mechanical energy converts into other energy forms, decreasing system efficiency
➡️ Energy conservation in ideal systems – Systems where no energy is lost and total mechanical energy remains constant
