What Is Energy Flashcards
What is the conservation of energy
Energy cannot be created or destroyed, only transferred from one energy store to another
What are the different energy stores
Kinetic Thermal
Chemical Magnetic
Gravitation Electrostatic
Elastic Nuclear
Kinetic energy
Stored in moving objects
What is the kinetic energy equation
Ek= 1/2 x m x v^2
Thermal energy
Kinetic energy in the vibrations of the particles in a solid liquid or gas
What does the temperature of an object depend on
The average kinetic energy of the particle
Chemical energy
Energy stored in chemical bonds between atoms in molecules
Nuclear energy
Released when a nucleus is split
Elastic potential energy
Energy stored in an object that has been stretched, twisted or deformed from its natural shape
Gravitational potential energy
Energy the object has because of its position in a gravitational field
Light energy
Transmitted by electromagnetic waves by oscillation in magnetic and electric fields
Elastics potential energy equation
Ee= 1/2 x k x e^2
