of the particle as the minimum speed (!)
$\begingroup$ First you need to define the energy of the gravitational field which itself is a thorny subject. The electric field has a scalar energy density field (or,following some older texts, a pressure field) associated with it. There is no nontrivial local energy-momentum tensor for the gravitational field in GR, so the best you can get is a pseudo-tensor (i.e. If total energy is negative: object will go into a circular or elliptical orbit or crash. Gravity - Gravity - Gravitational fields and the theory of general relativity: In Einstein’s theory of general relativity, the physical consequences of gravitational fields are stated in the following way. Space-time is a four-dimensional non-Euclidean continuum, and the curvature of the Riemannian geometry of space-time is produced by or related to the distribution of matter in the world.
When the field vector at a point is E, then the energy density at the same point is Gravitational potential energy (GPE) is an important physical concept that describes the energy something possesses due to its position in a gravitational field. Kinetic Energy and Total Energy As stated earlier, when asked to calculate the total energy of an orbiting satellite you must include both its gravitational potential energy and its kinetic energy. Escape velocity: "minimum speed of object to escape gravitational field of planet/travel to infinity, starting at the surface of a planet, without energy …
If total energy is zero: object will follow a parabolic path to infinity, where it will stop.
The GPE formula GPE = mgh shows that it depends on the mass of the object, the acceleration due to gravity and the height of the object. Examples of how to use “gravitational potential” in a sentence from the Cambridge Dictionary Labs Escape Velocity, Escape Energy As we noted in the previous section, a particle has ``escape energy'' if and only if its total energy is greater than or equal to zero. We define the escape velocity (a misnomer!) The gravitational field points toward the source mass in all known cases.
