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.
Imibuzo ebuzwa kaningi
Yini amandla anamandla okuphakelayo?
Le yi-energy etholakale yinto ngokunyuka kwayo ngokumelene nobunzima, PE = m × g × h. Isisindo se-2 kg esiphakama ama-m angu-10 ezweni sigcina ama-2 × 9.80665 × 10 ≈ 196 joules.
Ingabe amandla akhona axhomekeka kuphakama okubhekiswe kulo?
Yebo. I-PE ilinganiselwa ngokuphathelene nezinga lesibalo elikhethiwe, ngokuvamile i-ground. Ukuhlukana kuphela kobukhulu phakathi kwezinhlamvu ezimbili kunesici esibalulekile.
Ingabe ukunyakaza kweplanethi kwezinye iziplanethi kushintsha imiphumela?
I-PE ilingana ne-g, ngakho-ke i-lift efanayo igcina okuningi kuJupiter (g ≈ 24.8) futhi igcina okuncane kuMhlaba (g ≈ 1.62). Ukuphakamisa i-2 kg mass 10 m igcina okungaphezu kuka-196 J ezweni kodwa cishe 32 J kuphela eMhlaba.
Indlela ecalwa ngayo ijubane lokuhlaselwa ngokukhululekileyo?
Ukuwa kusuka ephakeme h, wonke amandla akhona azoba amandla kagesi, ngakho ½mv² = mgh unikeza v = √(2gh) — ohlukile kusisindo. Kusuka ku-10 m ezweni, okuwu-14 m/s, futhi i-calculator ibonisa lokhu kanye nokusebenza kwe-energy.
Ingabe amandla akhona ahlobene kanjani ne-kinetic energy?
Uma into iwela, amandla akhona aguqulwa abe amandla anamandla kanti okuphelele (ukukhohlwa ukumelana komoya) kuhlala kuqhubeka. Ukugcina amandla kuyisizathu sokuthi ijubane lokushaya lixhomekeke kuphela ekuphathweni, hhayi emthambekeni.
Yini ushintsho phakathi kwesisindo nesisindo lapha?
Ifomu lisebenzisa isisindo esiyikilograma; ubunzima (ubunzima bokuzizwa) yi m × g futhi sekuyisikhathi eside sifakwe ku-PE = mgh imvumo ngegama le-g, ngakho ufaka isisindo, hhayi ubunzima.
