Energy Changes in a System (OCR GCSE Physics A, Combined (Gateway Science Suite)): Flashcards

Stored by an object that is moving

Stored by magnets attracting or repelling each other

Stored in an object due to its heat

Stored in chemical bonds

Stored by charges attracting or repelling each other

Stored in object that's been stretched or compressed

Stored when object is lifted to a height

Stored inside the nuclei of atoms

Energy cannot be created or destroyed, only transferred

Energy transferred into a form that is not desired

Energy to raise 1 kg of substance by 1°C

$\frac{\text{Useful output}}{\text{Total input}}$

Heat travels through material more easily

Reduces friction, less energy lost as heat

Less energy is lost as heat
