Gravitational potential energy is the energy an object stores by virtue of its height in a gravitational field: PE = m × g × h, in joules, where m is mass in kilograms, g is the gravitational acceleration and h is the height it is raised. On Earth g is the standard 9.80665 m/s²; under advanced options you can switch to the Moon (1.62), Mars (3.72), Jupiter (24.79) and other bodies to see how the same lift stores very different amounts of energy. Choose which quantity to solve for — energy, mass or height — and the tool also reports the free-fall impact speed from that height, v = √(2gh).
As a worked example, lifting a 2 kg mass 10 m on Earth stores PE = 2 × 9.80665 × 10 ≈ 196 joules. Let it fall back and, ignoring air resistance, all of that converts to kinetic energy, so it lands at v = √(2 × 9.80665 × 10) ≈ 14 m/s. Take the identical lift to the Moon and only about 32 J is stored, because lunar gravity is roughly one-sixth of Earth’s.
Potential energy is measured relative to a chosen reference level — usually the ground — so only differences in height carry physical meaning. The concept underlies hydroelectric dams, pumped storage, pendulums, roller coasters and any situation where raising a mass banks energy that can later be released, and it pairs directly with kinetic energy through conservation of energy as objects rise and fall.
Mafunso ofunsidwa nthawi zambiri
Kodi ndi chiyani gravity mphamvu?
It is the energy an object gains by being raised against gravity, PE = m × g × h. A 2 kg mass lifted 10 m on Earth stores 2 × 9.80665 × 10 ≈ 196 joules.
Kodi mphamvu ya mphamvu imadalira pa kutalika kwa reference?
Yes. PE ndi kuwerengedwa mogwirizana ndi chosankha zero level, nthawi zambiri pansi. Only zosiyana mu utali pakati pa zidutswa ziwiri ndi zofunika zachikhalidwe.
Kodi gravity pa zina planets kusintha zotsatira?
PE ndi yofanana ndi g, kotero kunyamula kofananako kumasunga zambiri pa Jupiter (g ≈ 24.8) komanso pang'ono pa Mwezi (g ≈ 1.62).Kunyamula 2 kg ya maselo 10 m kumasunga pafupifupi 196 J padziko lapansi koma pafupifupi 32 J pa Mwezi.
Kodi ndi momwe kuphulika kwaulere kwa kuphulika kumawerengedwa?
Kugwa kuchokera pa kutalika h, zonse zofunikira mphamvu amasintha mphamvu kinetic, choncho ½mv² = mgh amapereka v = √ (2gh) — osati maselo. Kuchokera 10 m pa dziko lapansi kuti ndi zoposa 14 m / s, ndi calculator amasonyeza izi kumbuyo mphamvu.
Kodi mphamvu ya potaziyamu ndi yotani?
Mwachitsanzo, ngati chinthu chikugwa, mphamvu ya potaziyamu imasinthidwa kukhala mphamvu ya kinetic, ndipo mphamvu ya kinetic imasinthidwa kukhala mphamvu ya potaziyamu. Kusunga mphamvu ndi chifukwa chomwe chida chokhudzana chimadalirika pa kukula kwa chida chotuluka, osati pa kukula kwake.
Kodi pali kusiyana kotani pakati pa maselo ndi kunenepa?
Fomulesiyi imagwiritsa ntchito maselo m'makilogalamu; kulemera (kulemera kwa gravity) ndi m × g ndipo kale kuphika mu PE = mgh tanthauzo mwa g term, kotero inu mulowa maselo, osati kulemera.
