Aangaande hierdie sakrekenaar
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.
Dikwels gevra vrae
Wat is gravitasiepotensiaal?
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.
Hang potensiële energie van die verwysingshoogte af?
Ja. PE word gemeet aan'n vasgestelde nulvlak, gewoonlik die grond.'n Mens se vlak van net twee punte is fisies betekenisvol.
Hoe verander swaartekrag op ander planete die gevolg?
PE is gelyk aan g, en daarom is dieselfde hefkamere baie meer op Jupiter (g π 24,8) en baie minder op die Maan (g ← 1,62).'n 2 kg massa 10 m winkels is ongeveer 196 J op aarde groot, maar net om 32 J op die Maan.
Hoe word die kostering-werkingstempo bereken?
As jy van hoogte af kap, word al die potensiële energie kinetiese energie, so 1⁄2mv2 = mgh gee v = Ã2gh) Ã2gh) takies van massa. Van 10 m op Aarde wat ongeveer 14 m/s is, en die sakrekenaar wys dit langs die energie.
Hoe hou potensiële energie verband met kinetiese energie?
As'n voorwerp val, word potensiële energie na kinetiese energie omkeer terwyl die totale (ignorerende lugweerstand) voortdurend bly.
Wat is die verskil tussen massa en gewig hier?
Die formule gebruik massa in kilogram; die gewig (die gravitasiekrag) is m × g en word reeds in die PE = mgh uitdrukking deur die g term gebak, sodat jy massa binnegaan, nie gewig nie.
