I-Calculator ye-Force (F = ma)
Lungiselela umthetho wesithathu kaNewton wokusebenza, ubukhulu noma ukukhawulelwa.
Iziphetho zivuselelwa uma ubhala.
Malunga nale khadi
Newton's second law is the cornerstone of classical mechanics: the net force on an object equals 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 newtons (N), the SI unit of force defined as the force that gives a 1 kg mass an acceleration of 1 m/s². This calculator also converts to pound-force and kilogram-force, using 1 N = 0.2248 lbf = 0.1020 kgf.
Choose which quantity to solve for and enter the other two. For example, accelerating a 10 kg mass at 9.8 m/s² takes F = 10 × 9.8 = 98 N — which is also the weight of that mass on Earth, since weight is just the gravitational force m × g. Push a 1,500 kg car to 2 m/s² and you need 3,000 N; halve the mass or the acceleration and the force halves too, because force is directly proportional to both.
Force calculations underpin everything from working out the thrust a rocket needs and the braking force to stop a vehicle, to the tension in a lift cable and the recoil of a firearm. Keep the units consistent — kilograms, metres and seconds give newtons — and remember the law describes the net force: if several forces act, add them as vectors first, then divide by mass to get the actual acceleration.
Imibuzo ebuzwa kaningi
Yini umthetho wesithathu kaNewton?
Isho ukuthi amandla aphelele kunoma yini alingana nenani layo lesisindo kanye nesikhathi sokulinganisa, F = m × a. Ukulinganisa kabili inani lesisindo noma ukulinganisa kuphindeka amandla.
Yini i-newton?
I-Newton yiyunithi ye-SI yokusebenza: umsebenzi onikeza i-1 kg yesisindo ukukhawulelwa kwe-1 m/s². Kulingana no-0.2248 ama-pound-force.
Ngiyithola kanjani i-acceleration kusuka ku-force ne-mass?
Umthetho uphinde uhlukaniswe abe a = F / m. Umsebenzi ophelele we 3,000 N kumoto enamandla we 1,500 kg ukhiqiza 3,000 / 1,500 = 2 m/s² yokukhawulela. Ubukhulu besisindo kubonisa ukukhawulela okuncane kwemisebenzi efanayo.
Ingabe ubunzima bufana nokusebenza?
Ubunzima buyisimo esikhethekile sokusebenza kwengcindezi esigabeni, W = m × g, nge g ≈ 9.81 m/s² ezweni. Ngakho-ke isigabeni esingu-10 kg siyisisindo esingu-98 N. Isigabeni sihlala sifana kuwo wonke amaphuzu; ubunzima bushintsha ngobukhulu bendawo.
Yini ushintsho phakathi kwesisindo nesimo?
Isisindo (amakhilogremu) silinganisela ukuthi iyiphi into equkethe impahla futhi imelana nokuthuthuka; amandla (ama-newtons) ucindezela noma ucindezela. Zixhunywe ngu-F = m × a kodwa ziyizibalo ezahlukene ngeyunithi ezahlukene.
Yini okusho "net force" kufomula?
I-vector sum yezo zonke izimo ezisebenza kuleso sici. Uma u-100 N ucindezela uhlangabezana ne-30 N ucindezela, i-net force yi-70 N, futhi yileyo inombolo echaza ukukhawulelwa okungokoqobo.
Ngiguqula kanjani ama-newtons abe ama-pund-force noma ama-kilogram-force?
Ukuphindaphinda ama-newtons ngo-0.2248 nge-pounds-force noma ngo-0.1020 nge-kilograms-force. Ngakho-ke u-98 N ulingana no-22 lbf noma u-10 kgf — i-calculator ibonisa ukuguqulwa okufanayo.
