Tentang kalkulator ini
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.
Sering kali mengajukan pertanyaan
Apa itu energi potensial gravitasi?
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.
Apakah energi potensial bergantung pada tinggi referensi?
Ya, PE diukur relatif terhadap nol tingkat yang dipilih, biasanya tanah, hanya perbedaan antara dua titik berarti secara fisik.
Bagaimana gravitasi di planet lain mengubah hasilnya?
PE is proportional to g, so the same lift stores far more on Jupiter (g ≈ 24.8) and far less on the Moon (g ≈ 1.62). Raising a 2 kg mass 10 m stores about 196 J on Earth but only around 32 J on the Moon.
Bagaimana dampak jatuh Gratis dihitung kecepatan?
Dropping from height h, all the potential energy becomes kinetic energy, so ½mv² = mgh gives v = √(2gh) — independent of mass. From 10 m on Earth that is about 14 m/s, and the calculator shows this alongside the energy.
Bagaimana energi potensial berhubungan dengan energi kinetik?
Sebagai objek jatuh, energi potensial mengubah energi kinetik sementara total (pemtahanan udara yang tidak mengenal panjang) tetap konstan.
Apa perbedaan antara massa dan berat di sini?
Formula ini menggunakan massa dalam kilogram; berat (gaya gravitasi) adalah m × g dan telah dipanggang ke PE = ekspresi g melalui istilah g, sehingga Anda memasukkan massa, bukan berat badan.
