Potential energy of a planet
WebObjects accelerate towards the Earth, thus losing their gravitational energy and transforming it into kinetic energy. Gravitational energy or gravitational potential energy is the potential … Web30 Dec 2024 · 1] If we choose a planet’s surface as the zero level or reference, Gravitational Potential Energy Ep at x has a positive value. If infinity is chosen as the zero level, Ep has a negative value. 2] Gravitational potential energy Ep = (mg) × h = mgh (if we choose a planet’s surface as the zero level or reference)
Potential energy of a planet
Did you know?
In physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors. The term potential energy was introduced by the 19th-century Scottish engineer and physicist William Rankine, although it has links to the ancient Greek philosopher Aristotle's concept of potentiality. http://hyperphysics.phy-astr.gsu.edu/hbase/gpot.html

Potential energy is particularly useful for forces that change with position, as the gravitational force does over large distances. In Potential Energy and Conservation of Energy, we showed that the change in gravitational potential energy near Earth’s surface is ΔU = mg(y2 −y1) Δ U = m g ( y 2 − y 1).

Compare this to the escape speed from … See more We use (Figure), clearly defining the values of R and M. To escape Earth, we need the mass and radius of Earth. For escaping the Sun, we need the mass of the Sun, and the orbital distance between Earth and the Sun. See more The speed needed to escape the Sun (leave the solar system) is nearly four times the escape speed from Earth’s surface. But there is help in both cases.
