What type of energy is possessed by a planet revolving around sun?
It is a combination of kinetic energy, and potential energy. Kinetic energy is related to the planet's movement; and the farther away a planet is from the Sun, the greater its potential energy.
What is potential energy of a satellite?
The potential energy of a satellite in orbit around a planet is due to the gravitational attraction between the satellite and the planet. It is a type of energy that depends on the satellite's position relative to the planet, and is higher the higher the satellite is from the planet's surface. Mathematically, the potential energy of a satellite can be calculated using the formula: PE = - G * (m1 * m2) / r, where G is the gravitational constant, m1 and m2 are the masses of the planet and satellite, and r is the distance between their centers.
How can you increase an object's gravitational potential energy?
By raising the object to a higher position. The potential energy also depends on the force of gravity, and on the object's mass, but for a given object (and for a given planet!), you have no control over these.
What is the formula to solve for gravitational potential energy?
Formula for Gravitational potential is - G M / r Here G is universal Gravitation constant, M - mass of the planet and r is the distance of the point from the centre of the planet. The unit is J/kg If potential energy is needed then the potential is to be multiplied by the mass m. So gravitational potential energy = - G M m / r So the unit would be J (joule)
As a planet approaches perihelion does it potential energy increase or decrease?
At perihelion, the planet is closer to the Sun, and moves faster, that means that the potential energy is at a minimum, and the kinetic energy at a maximum. The sum of kinetic + potential energy, of course, remains constant.At perihelion, the planet is closer to the Sun, and moves faster, that means that the potential energy is at a minimum, and the kinetic energy at a maximum.

Which planet has the least gravitational potential energy when lifted to a height of 1 m if you drop a 30kg bowling ball?
The planet with the least gravitational potential energy when a 30kg bowling ball is lifted to a height of 1m would be the planet with the lowest surface gravity. As an approximation, if we consider only the eight planets in our solar system, Mercury has the lowest surface gravity, followed by Mars. So, if you were to drop a 30kg bowling ball from a height of 1m on either Mercury or Mars, it would have the least gravitational potential energy relative to the other planets.
What is gavitational potential energy?
It represents energy that can be released by dropping a mass, which causes it to gain potential energy as it falls and accelerates. Gravitational potential energy is also noticed in planets' orbits, because as a planet goes round in its elliptical orbit it speeds up and slows down, in such a way that the sum of kinetic energy and potential energy stays constant.
What do you mean by the orbital energy of an orbiting object?
Orbital energy is the sum of an object's kinetic energy and gravitational potential energy while it is in orbit around another object, such as a planet or a star. It dictates the object's total energy in that orbit and is crucial for understanding its motion and stability in space.
What two variables does gravitational energy depend on?
Gravitational energy depends on the masses involved and their distances. For a small (relative to planet-sized masses) mass in a gravitational field, the gravitational potential energy is equal to mgh, where m is the mass of the small mass, g is the gravitational acceleration in the gravitational field, and h is the height of the small mass above the reference surface. This is exactly analogous to the above situation except that the distance has been changed to height above a reference surface in the large (planetary) mass' gravitational field.
How is the escape velocity equation derived?
The escape velocity equation is derived by setting the kinetic energy of an object equal to the gravitational potential energy at the surface of a planet. By equating these two energies, we can solve for the velocity needed for an object to escape the planet's gravitational pull. The equation is derived using principles of energy conservation and Newton's laws of motion.
What factor affects potential energy?
The equation for Potential Energy isU=mghWhere:U=Potential energym= MassG= acceleration due to gravity which is 9.81m/s/s on Earthh= heightTherefore, the factors that affect potential energy are mass and height. Technically also gravity but if the experiment is carried out on the same planet, satellite etc then it should be constant.
What is the derivation of the escape velocity?
The escape velocity is derived from the gravitational potential energy and kinetic energy equations, taking into account the mass of the object and the distance from the center of the gravitational field. It represents the minimum velocity needed for an object to break free from the gravitational pull of a celestial body, such as a planet or a star.
