Die sewende, hersiene uitgawe van die Nasionale Woordeboek definieer massa soos volg:

"... die hoeveelheid materie waaruit 'n liggaam bestaan, gemeet in kilogram..."

As ek dus sê dat ek 55 kg weeg, bedoel ek dat die hoeveelheid materie waaruit my liggaam bestaan, 55 kg is.

Die massa van 'n voorwerp gee dus 'n aanduiding van die hoeveelheid materie wat die voorwerp bevat.

Die term gewig se definisie lui weer soos volg:

"... die krag waarmee die aarde of 'n ander hemelliggaam 'n voorwerp aantrek..."

Dit is ook belangrik om te weet dat alle vorme van materie (vastestowwe, vloeistowwe en gasse) massa het.

Skryf in jou eie woorde neer wat die verskil tussen massa en gewig is.

Assessering

Leeruitkomste 1: Die leerder is in staat om met selfvertroue op weetgierigheid oor natuurlike verskynsels te reageer, en om binne die konteks van wetenskap, tegnologie en die omgewing verbande te ondersoek en probleme op te los.

Assesseringstandaard 1.1: Dit is duidelik wanneer die leerder ondersoeke beplan: beplan eenvoudige toetse en vergelykings en bedink hoe om dit deeglik uit te voer.

Leeruitkomste 2: Die leerder ken, interpreteer en pas wetenskaplike, tegnologiese en omgewingskennis toe.

Assesseringstandaard 2.3: Dit is duidelik wanneer die leerder inligting interpreteer: identifiseer kernidees in die teks, vind patrone in aangetekende data en maak gevolgtrekkings uit inligting in verskeie vorme (prente, diagramme, ens.).

in what situation (s) would be the use of a scanning electron microscope be ideal and why?
Kenna Reply
A scanning electron microscope (SEM) is ideal for situations requiring high-resolution imaging of surfaces. It is commonly used in materials science, biology, and geology to examine the topography and composition of samples at a nanoscale level. SEM is particularly useful for studying fine details,
