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 ebuza rhoqo
Yintoni uxinzelelo olunokwenzeka lwengxolo?
Le yi-energy efunyenwe yinto ngokunyuka phantsi koxinzelelo lwesinyithi, PE = m × g × h. I-2 kg yomthwalo onyuka 10 m emhlabeni igcina i-2 × 9.80665 × 10 ≈ 196 joules.
Ingaba amandla anamandla axhomekeke kuphakamo obhekiswe kulo?
Ewe. I-PE ilinganiselwa ngokuhambelana nomphakamo okhethiweyo ongekho ngaphantsi, oqhelekileyo umhlaba. Kuzo kuphela iindidi zobude phakathi kweendawo ezimbini ezinophawu olubonakalayo.
Ubunzima bezinto ezijikelezayo kwezinye iiplanethi butshintsha njani impumelelo?
I-PE ilingana ne-g, ngoko ukunyuka okufanayo kugcinwa ngaphezu kweJupiter (g ≈ 24.8) kwaye ngaphantsi kweNyanga (g ≈ 1.62). Ukunyuka kwe-2 kg yomthwalo 10 m kugcinwa malunga ne-196 J kwihlabathi kodwa kuphela malunga ne-32 J kwiNyanga.
Ukhawulezo lokubetha olusuka ekungeneni ngokukhululekileyo luxabiswa njani?
Ukuwa ukusuka kumphakamo h, onke amandla anamandla avela kumandla anamandla, ngoko ½mv² = mgh inika v = √(2gh) - ikhululekileyo kwisisindo. Kusuka kwi-10 m emhlabeni oko kumalunga ne-14 m/s, kwaye i-calculator ibonisa oku kufutshane nomandla.
Umandla onamandla ahambelana njani nomandla ojikelezayo?
Xa into iwela, amandla anamandla aguqulwa abe amandla anamandla ngelixa okupheleleyo (ukuyeka ukumelana nomoya) kuhlala kuqhubeka. Ukugcina amandla kubangela ukuba ukhawulezo lokubetha luxhomekeke kuphela kuphakamo lokuwa, hayi kubunzima.
Yintoni utshintsho phakathi kwesisindo kunye nobunzima apha?
Ifomula isebenzisa umthamo kwi kilogram; ubunzima (umandla woxinzelelo) ngu m × g kwaye sele uphekwe kwi PE = mgh ulwimi ngegama le g, ngoko ufaka umthamo, hayi ubunzima.
