Today i'm going to discuss on SPM physics definition that can come out in paper 2 section A, B or C. Although there are a lots of definition need to be memorised, in average only 3 to 4 definition will be asked in the exam. Each definition contributes one mark only. If u are aiming for A+, u cant afford to loose too many marks. So its up to u, whether u want to grab all the marks on definition or to 'sedekah' some of them :)
Some definition can defined straight forward by referring to its formula. For example, pressure can be defined as Force acting per unit area ( P=F/A) or resistance can be defined as ratio of potential differnt over current (R=V/I).
However please be careful because not all definition can be defined based on its formula. For example u can't define potential different by using V=IR. If u say that potential different equals to product of current and resistance, u 'll lose the mark. In fact to define it, u should refer to its fundamental equation, i.e V=E/Q. Thus potential different is defined as 'energy needed to move a unit charge from one point to another'.
Some of the definition does not belong to any equation. For example elasticity is defined as 'the property of an object that enables it to return to its original shape after an applied external force is removed'
This kind of definition will be easier to memorise if u fully understand the keyword used to describe it. Basically once u can understand the physics concept being discussed, its much easier for u to memorize the definition.
