Te tātaitai tōpana (F = ma)
Whakaroatia te ture tuarua a Newton mō te tōpana, te nuinga, te tere rānei.
Ka whakahōutia ngā hua i te wā e tātuhi ana.
Mo tēnei tātaitai
the second law of Newton, the net force on an object is equal to its mass times its acceleration, F = m × a. Rearranged, the acceleration a body undergoes is a = F / m, and the mass implied by a known force and acceleration is m = F / a. The result is in pound-force (N) and kilogram-force (kgf). This calculator also converts to pound-force and kilogram-force, using 1 N = 0.2248 lbf = 0.10
Ko nga pātai e pā ana
He aha te ture tuarua a Newton?
E kī ana he ōrite te tōpana tīariari i runga i tētahi ahanoa ki tōna taumahatanga, F = m × a. Ka rua te taumahatanga, te whakateretanga rānei ka rua te tōpana.
He aha te Newton?
Ko te Newton te wae o te tōpana SI: ko te tōpana e hoatu ana ki te taumahatanga 1 kg he tere o te 1 m/s². e ōrite ana ki te 0.2248 pounds-pūnga.
He pēhea te kimi i te tere mai i te tōpana me te nui?
Ka whakahōu anō te ture ki a = F / m. Ko te tōpana tīariari 3,000 N i runga i tētahi 1,500 kg o te waka e whakaputa ana i te 3,000 / 1,500 = 2 m/s² o te tere. Ko te nuinga nui ake ko te tikanga he iti iho te tere mo te tōpana ōrite.
He ōrite te taumaha ki te tōpana?
Ko te taumaha ko te tōpana ā-papa motuhake i runga i tētahi taumaha, W = m × g, me te g ≈ 9.81 m/s² i runga i te Earth. Nā reira ko te taumahatanga o te 10 kg e tata ana ki te 98 N. Ka noho ōrite te taumahatanga i ngā wāhi katoa; Ka rerekē te taumahatanga me te tō ā-papa paetata.
He aha te rerekētanga i waenganui i te nuinga me te kaha?
Ko te nuinga (ki te kila) e ine ana i te nui o te take o tētahi ahanoa, ā, ka ātetetia te tere; ko te tōpana (Newtons) he whakahau, he whakahau rānei. E honoa ana rātau e F = m × a engari he rerekē ngā nui me ngā wae rerekē.
He aha te tikanga o te "pūngao tīariari" i roto i te tātai?
Ko te taumahatanga rarangi o ngā tōpana katoa e mahi ana ki runga i te ahanoa. Mēnā he 100 N te whakahauhau e tūtaki ana i tētahi tōpana whakaroa 30 N, ko te tōpana tīariari ko te 70 N, ā, ko taua uara e whakatau ana i te whakateretanga tūturu.
He pēhea te tahuri i a Newton ki te pūngao-pūngao, ki te pūngao-kiomio rānei?
Whakarea ngā Newtons e 0.2248 mō te pūngao pūngao, e 0.1020 rānei mō te pūngao kiloko. Nā reira, e 98 N tata ki te 22 lbf, 10 kgf rānei — ka whakaaturia ngā tatauranga e rua i ngā tahuritanga.
