A plane in the air posseses gravitational potential energy or stored energy. If the pilot shuts the engine off the plane releases that energy.
Any object that is higher than ground level in earth's gravitational field has potential energy stored in it. Examples: 1. A plane or bird in the sky 2. A parachutist 3. Water stored in a dam, or water tanks at some height above earth's surface 4. A satellite orbiting Earth
Two of the biggest areas of energy study in high school physics is kinetic energy (energy of an object that is moving) and potential energy (the potential of an object to do work - such as being being at the top of an inclined plane). However there are MANY other forms of energy.
gravity of earth is constant in any plane but the acceleration may vary becoz of irregular plane
Energy is transferred into an inclined by effort
The kinetic energy of an object varies as the square of its velocity (Kinetic energy = mv2/2). So a plane with the same mass travelling at 3 times the velocity will have 9 times the kinetic energy.
The object's height and gravitational potential energy both increase.
the stretch of the rubber band cause elastic energy the movement of the plane cause kinetic energy and the height causes gravitational potential energy
Then efficiency would become more than one. This leads to the concept of creating energy which is against the law of conservation of energy. If there is a gravitational incline, moving down the plane can give an output of work greater than the "immediate" input, because of the gravitational potential energy. So if you ignored the gravitational potential energy, the output could be greater. If you don't ignore the gravity, then no; you can't create energy, you can only transform energy.
That might refer to the fuel, which has chemical energy. Also, any object that is above a reference level (for instance, the ground level) has gravitational potential energy. That energy isn't stored in a specific place; it is related to the interaction between the two objects - in this case, the plane and the Earth.
Gravitational potential energy is converted into kinetic energy.

No, it's losing potential energy, since it gets lower.
When an object is stationary in a plane, (no hill or slope) then potential energy and kinetic energy are equal. Following the case, if an object is stationary at the top of a hill, it has stored energy (potential energy) due to gravitational attraction, as the force of gravity attracts the object towards the ground and once the object gets some kind of motion, all those potential energy will change to kinetic energy. **************************** Actually, the Object CAN be moving, but it is moving Parallel to its Reference Frame, and at a Constant Velocity.

A person parachuting from a plane has already acquired potential energy by rising to whatever altitude the plane is at-this energy has been obtained from the fuel used by the plane. This energy is then turned into kinetic energy as a result of the earth's gravitational attraction, and the parachutist goes into freefall. Braking the speed of fall to make a safe landing, the kinetic energy is returned to the air which is slowing the parachute. The net change when the person lands is zero.
