# mechanic

Notes

# mechanical energy Energy associated with the Motion (Kinetic), Position (Potential) or shape of an object. Anything that requires a motor to operate is mechanical energy. what is transfer? Transfer is to move from one place to another. what is power Power is how fast energy transfers (how fast or slow) the relationship between power, energy and work is that without energy, none of them can function. energy → power → work law of conservation of energy Energy can't be created or destroyed. It can only be converted or transferred from one form to another or transform. Total amount of energy always remains the same. potential energy · Energy due to height of an object Stored energy · Mass and height is used to determine the amount of potential energy. Gravitational and elastic energy are both types of potential energy. Kinetic energy Energy from motion. The faster an object is, the higher the kinetic energy. Depends on: Mass and Speed. what is energy? Energy is the ability to do work and cause change what is work? Work is the transfer of energy Work=force X distance Work depends on both FORCE and DISTANCE. Joule (J) is unit for work.
