3 Undersoek die verwantskap tussen krag en
Eksperiment 1
versnelling
In hierdie eksperiment sal jy:
die versnelling van 'n trollie meet met tikkerlint wat die trollie deur 'n
tydtikker trek
'n netto krag op 'n trollie toepas deur rekkies wat ewe veel gerek is, aan te
o
heg. Die netto krag Fnetto is eweredig aan die getal rekkies.
die versnelling van die trollie vergelyk wanneer verskillende kragte daaro
O
toegepas word
die verwantskap tussen die netto krag op 'n trollie en die versnelling var
die trollie ondersoek.
HIPOTESE
Skryf 'n hipotese vir die ondersoek.​

An  atom  (ours, not carroll's) consists of a positively charged  nucleus, surrounded by one or more negatively charged particles called  electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6  nm.  *  if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -
