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.
Mafunso ofunsidwa nthawi zambiri
Kodi ndi chiyani lamulo lachiwiri la Newton?
Mfundo yoyamba ya physics ndi mfundo yoti mphamvu yogwira ntchito pa chinthu ndi yofanana ndi kutalika kwa maselo ake nthawi ya kufulumira kwake, F = m × a.
Kodi ndi chiyani Newton?
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.
Kodi ndingapeze bwanji kufulumira kuchokera ku mphamvu ndi masa?
Kusintha kwa malamulo ku a = F / m. A 3,000 N mphamvu ya net pa 1,500 kg katundu amapanga 3,000 / 1,500 = 2 m / s² ya kufulumira. Kukula kwa maselo kumatanthauza kufulumira pang'ono kwa mphamvu yomweyo.
Kodi kulemera kwake ndi kofanana ndi mphamvu?
Kulemera kwake ndi mphamvu ya gravity pa maselo, W = m × g, ndi g ≈ 9.81 m / s² padziko lapansi. Kulemera kwa 10 kg kumalemera pafupifupi 98 N. Maselo amakhazikika pamodzi kuzungulira; Kulemera kwake kumasintha ndi gravity yamalo.
Kodi pali kusiyana kotani pakati pa maselo ndi mphamvu?
Mphamvu ya kuzungulira (kuzungulira) ndi mphamvu ya kuzungulira (kuzungulira) ndi mfundo zosiyana. Mphamvu ya kuzungulira ndi mphamvu ya kuzungulira ndi mfundo zosiyana. Mphamvu ya kuzungulira ndi mfundo zosiyana.
Kodi "kuchita bwino" kumatanthauza chiyani mu formula?
It is the vector sum of all forces acting on the object. If a 100 N push meets a 30 N friction force, the net force is 70 N, and that is the value that determines the actual acceleration.
Kodi ndingasinthire bwanji Newtons kuti pounds-force kapena kilograms-force?
Kuwonjezera Newtons ndi 0.2248 kwa masentimita-kulimbana kapena ndi 0.1020 kwa masentimita-kulimbana. So 98 N ndi zokhudza 22 lbf kapena 10 kgf — calculator amasonyeza onse kusinthidwa mwamsanga.
