science energy Flashcards
Radiant energy
The energy of light
Thermal energy
Heat or temperature of an object (all objects have it
Electrical energy
A type of kinetic energy cause by by moving electric charges
Mechanical energy
Energy due to motion and position of an object
Nuclear energy
Energy stored in the nucleus of an object
Chemical energy
Stored energy (potential energy) it is stored in the bonds between atoms and molecules. Chemical energy holds the atom in the molecule together.
Law of conservation of energy
States energy cannot be created or destroyed, but can be transformed into a new energy.
Work
The use of force to move an object. For work to be done, the force must be applied in the same direction that the object is.
Force
An action that changes or maintains the motion of a body or object. A force is a push or pull. Forces can change objects speed.
Potential energy
Is the stored energy a object has because of its position or state.
Kinetic energy
Is the energy of moving matter.
Electrical circuit
It is a closed loop through which electric current can flow. A circuit must include a source of voltage and conductors such as wires to carry the current from the source of voltage and back again.
