Maphunziro Oyambira a Fiziki

Mfundo ya Mphamvu ya Ntchito ndi Kinetic

Ngati mphamvu ya neti ikugwira ntchito pa chinthu, chinthucho chimapeza kufulumira (chinthucho chimapeza kusuntha). Chinthucho chikapeza kufulumira, liwiro la chinthucho limasintha. Mwa kuyankhula kwina, ntchito yochitidwa ndi mphamvu ya neti imakhudzana ndi liwiro loyamba ndi lomaliza la chinthucho.

Ntchito yochitidwa pa chinthu ndi mphamvu yokhazikika ndi iyi:

W _net = ΣF s

Lamulo lachiwiri la Newton limati ngati pali mphamvu yogwira ntchito pa chinthu, chinthucho chimathamanga.

1.1 Tanthauzo la Ntchito

Ngati muikankhira buku pamwamba pa tebulo mpaka buku litasunthika, mumauzidwa kuti mwagwira ntchito pa bukulo. Ngati chinthu chagwa pansi chifukwa cha kukoka kwa mphamvu yokoka, mphamvu yokoka imanenedwa kuti yagwira ntchito pa chinthucho. M'malo mwake, ngati muikankhira chinthu ndi mphamvu zanu zonse mpaka kutuluka thukuta kwambiri, koma chinthucho sichikusuntha konse, mumanenedwa kuti simunagwire ntchito pa chinthucho. M'moyo watsiku ndi tsiku, anthu anganene kuti mwagwira ntchito molimbika pokankhira chinthucho koma mu Fizikiki, simugwira ntchito pa chinthucho chifukwa palibe kusunthika kwa chinthucho.
