Tunhnaiah
Khawbel khuaa thilthleng whatsapp leh fb velah a darh nual a. Kei
pawhin ka dawng ta malh malh mai a(atam zawk chuan hrilhfian turin min
ngen a). Mizote hi tunhma atanga zeldin thubawl leh tapchhak titi ching
kan nih avang hian thil ni thei miah lo hi sawi kan la ching viau mai a.
Heti ang chi hi society atanga nuaibotu nih ve hi kan tangkaina pakhat
ve niin ka inngai a. tin, keimahni lam kaihnawihte a nih avangin
hrilhfiah ka lo tum ang e.
Thil pahnih engpawh hi an inhip vek a chu chu Newton's law of universal gravitation an ti a. Chu hipna chu a inhipate a len poh leh a na a ni (force a tam tihna). Kawlbem khuaa nufa ft 30 a sanga zuang thlate pawh kha khawvel (earth) nena inhipna vang a ni a. A nu zawk kha a let 5 velin lo rit zawk ta se, lei nena a inhipna chu a let 5in a fapa aiin a chak zawk dawn tihna a ni. Hemi thleng hi Physics background nei lo chuan kan suangtuah thiam niin a lang a. Hemi avang hian anu zawk kha thleng hmasa viau zawk turah kan ngai niin a pawm theih a.
Amaherawhchu, khialaia inhipa force piah lamah khian thildang (parameter dang) lo lang leh a awm a. Chu chu acceleration a ni a. Acceleration chu second khat (hun/time) chhunga a kal chak zawng tiin dah tawp ila kan hrethiam ang chu maw... Chuan thil pahnih an inhip hian khilaia acceleration kan tih a ritah a tlem zawk zel a. A saptawng chuan inversely proportional to mass (a=F/m) a ni. Chumi awmzia chu kan sawi hmasak conditionah khan rihna ngah zawk khan force nei tam mah se acceleration a neih tlem zawk avangin a kal chak bik dawn lo tihna a lo nih chu...
Tin, engpawh hi lei chung atang kan thlak hian a kal chak zawng hi thil rih zawngah a innghat miah lo a. Hei pawh hi universal law awmsa - conservation of energy law hmangin awlsamtein a finfiah theih a. Entirnan a nu zawk rih zawng kha 'm' ni ta se, chuan a zuanna san zawng kha 'h' ni bawk ta se, Energy (potential) a neih zat chu:
PE=mgh (g=lei hipa avanga acceleration lo awm)
A zuan thlak chiah khan khi laia a chakna neih zawng zawng khi Kinetic energy-ah a inthlak anga, heti angin:
KE=1/2mv^2
Mahse KE leh PE hi an inang a chuvangin heti ang hi kan nei leh ang a:
v=sqr2gh tiin.
Chumi awmzi chu thil engpawh hi an tlak thlak chuan an kal chak zawng hi an rihnaah an innghat lo tihna a ni. Chumi awmzia chu Pi Lalnunhlimi leh a fapa chu a rual chiaha an zuan pawhin thleng hmasa zawk awm loin an thleng rual dawn tihna a lo ni a. Anu zawk hi a zuan hnuhnun zawk phei chuan a thleng tlai zawk dawn tihna a ni.
Khilaia ka hrilhfiahna khi free falling behchhan a la ni cheu a. Free falling kan tih chu boruak avanga lo nekkawitu leh dangtu awmlo anga kan ngaih hi a ni. Boruak avanga nekkawina emaw dangtu emaw kan la ngaihtuah tel chuan ball - pianhmang inang chiah chiah pawh hi a lian zawk leh rit zawk chu thleng har zawk tura chhut a ni a. Chuvangin a rualin zuang pawh nise anu zawk khi a thleng tlai hret dawn a lo ni.
Khawbel khuaa thilthleng hi information peksual avang a nih loh pawhin sawi uar hret an awm a ni ang.
