Malunga nale Calculator
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 ebuza rhoqo
Yintoni umthetho wesibini kaNewton?
Ichaza ukuba amandla apheleleyo kwizinto alingana nesisindo sazo phinda-phinda ukukhawulezisa, F = m × a. Ukuphinda-phinda isisindo okanye ukukhawulezisa kuphinda-phinda amandla.
Yintoni i-newton?
I-newton yiyunithi ye-SI yoxinzelelo: uxinzelelo olunika i-1 kg yomthwalo ukhawuleziso lwe-1 m/s². Ilingana malunga ne-0.2248 yee-pund zoxinzelelo.
Ndiyifumana njani intshukumo esuka kumandla kunye nobunzima?
Umthetho uphinde ucwangciswe kwakhona ukuba ube yi a = F / m. Umandla opheleleyo we-3,000 N kwimoto ye-1,500 kg uvelisa unamandla ombane o-3,000 / 1,500 = 2 m/s². Ubunzima obukhulu kuthetha unamandla aphantsi onamandla afanayo.
Ingaba ubunzima bufana nobunzima obunamandla?
Ubunzima buyimfuneko yoxinzelelo lokutsala kwisisindo, W = m × g, nge g ≈ 9.81 m/s² emhlabeni. Ngoko ke i-10 kg yesisindo siyi-98 N. Isisindo sihlala sifana naphi na; ubunzima butshintsha ngoxinzelelo olungaphakathi.
Yintoni utshintsho phakathi kwesisindo kunye nobunzima?
Ubunzima (iikilogram) bulinganisela ukuba yintoni eninzi into equlethe kwaye imelana nokukhawuleza; ubunzima (ii-newtons) butyhala okanye butsala. Badityaniswa ngu F = m × a kodwa zizinto ezihlukileyo ezinomlinganiselo kunye neeyunithi ezahlukeneyo.
Yintoni "i-net force" ethetha ngayo kwifomula?
I-vector sum yezo zonke ii-forces ezisebenza kwi-object. Ukuba i-100 N yokuthambisa idibana ne-30 N yoxinzelelo, i-net force yi-70 N, kwaye le yixabiso elichaza ukhawuleziso olukhoyo.
Ndiguqula njani i-newtons ibe yi-pund-force okanye i-kilogram-force?
Multiply newtons by 0.2248 for pounds-force or by 0.1020 for kilograms-force. So 98 N is about 22 lbf or 10 kgf — the calculator shows both conversions automatically.
