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.
Kesyon ki poze souvan
Ki sa ki se enèji potansyèl gravitasyonèl?
Li se enèji yon objè jwenn lè li leve kont gravite, PE = m × g × h. Yon mas 2 kg leve 10 m sou tè a estoke 2 × 9.80665 × 10 ≈ 196 joules.
Èske enèji potansyèl la depann de wotè referans la?
Wi. PE a mezire relativman a yon nivo zewo chwazi, anjeneral tè a. Se sèlman diferans nan wotè ant de pwen ki gen siyifikasyon fizik.
Ki jan gravite sou lòt planèt yo chanje rezilta a?
PE se pwopòsyonèl ak g, se konsa menm leve a estoke anpil plis sou Jupiter (g ≈ 24.8) ak anpil mwens sou Lune (g ≈ 1.62). leve yon mas 2 kg 10 m estoke sou 196 J sou tè a men sèlman sou 32 J sou Lune.
Ki jan vitè a nan yon frape tonbe gratis se kalkule?
Si yon objè tonbe soti nan yon wotè h, tout enèji potansyèl li genyen an vin enèji kinetik, se konsa ½mv² = mgh bay v = √(2gh) — ki pa gen rapò ak mas la. Soti nan 10 m sou tè a sa se sou 14 m/s, ak kalkulatè a montre sa ansanm ak enèji a.
Ki jan enèji potansyèl la gen rapò ak enèji kinetik la?
Lè yon objè tonbe, enèji potansyèl la konvèti nan enèji kinetik pandan ke total la (ki pa pran an kont rezistans lè a) rete konstan.Sa a konsèvasyon enèji se poukisa vitès la nan enpak la depann sèlman sou wotè a nan tonbe a, pa mas la.
Ki diferans ki genyen ant mas ak pwa?
Formule a itilize mas nan kilogram; pwa (fòs gravitasyonèl) se m × g ak se deja kwit nan ekspresyon an PE = mgh pa tèm g, se konsa ou antre mas, pa pwa.
