Aangaande hierdie sakrekenaar
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.
Dikwels gevra vrae
Wat is Newton se tweede wet?
Dit sê dat die netkrag op'n voorwerp gelyk is aan sy massa maal sy versnelling, F = m × a.'n Verlaaging van die massa of die versnelling verdubbel die krag.
Wat is'n nuweton?
A newton is the SI unit of force: the force that gives a 1 kg mass an acceleration of 1 m/s². It equals about 0.2248 pounds-force.
Hoe vind ek versnelling van krag en massa?
Die wet word aan'n = F / m gegee.'n 3 000 N netmag op'n 1 500 kilogrammotor produseer 3 000 / 1 500 = 2 m/s2 van versnelling. Groter massa beteken minder versnelling vir dieselfde krag.
Is gewig dieselfde as krag?
Gewig is die spesifieke gravitasiekrag op'n massa, W = m × g, met g π 9,81 m/s2 op Aarde.'n 10 kgmassa weeg dus ongeveer 98 N. Mass bly oral dieselfde; gewigsveranderinge met plaaslike swaartekrag.
Wat is die verskil tussen massa en mag?
Die mis (kilogramme) meet hoeveel materie'n voorwerp bevat en weerstaan versnelling; krag (nettels) is'n stoot of trek.'n Mens word met F = m × a verbind, maar hulle is verskillende hoeveelhede met verskillende eenhede.
Wat beteken "netkrag" in die formule?
Dit is die vektor-waarde van alle kragte wat op die voorwerp werk. As 'n 100 N-modisie voldoen aan 'n 30 N wrywingskrag, is die netkrag 70 N, en dit is die waarde wat bepaal die werklike versnelling.
Hoe omskep ek newtone tot kilogramme-krag of kilogram-krag?
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.
