Question

If a body is raised to a height then it gains potential energy so if the body goes at a very big height and gains a high pe then when escapes into space where there is no gravity where does the pe goes

Answer 1

Gravitational potential energy (PEg) gains significance with the work done against a gravitational field. Once an object is beyond the influence of Earth's gravity, this type of potential energy ceases to exist but transforms into kinetic energy or is conceptually dispersed.

Step-by-step explanation:

When an object is lifted to a height, it gains gravitational potential energy (PEg) due to the work done against Earth's gravity. This energy is calculated as PEg = mgh, where m is the mass, g is the acceleration due to gravity, and h is the height. When an object is taken to a location where there is no gravity, such as far out in space, the concept of gravitational potential energy as defined by this equation no longer applies since g approaches zero. Instead, the object would have its kinetic energy based on its velocity and the conservation of energy applies.

The change in gravitational potential energy is significant only when there is a change in position within a gravitational field. As an object ascends from Earth's surface and eventually escapes its gravitational pull, the gravitational potential energy effectively decreases to zero beyond the gravitational influence of Earth. The energy does not disappear but transitions to other forms, primarily kinetic energy if it's moving, or may be considered to be infinitely dispersed in the case where the object is brought to rest at an infinite distance from any other mass.

Answer 2

When a body gains potential energy by being raised to a height, that potential energy does not simply disappear when the body escapes into space. Instead, it is transformed into other forms of energy, such as kinetic energy, thermal energy, or electromagnetic energy.

Step-by-step explanation:

When a body is raised to a height, it gains potential energy. The potential energy is the energy associated with the state of separation between two objects that attract each other by the gravitational force. If the body goes to a very high height and gains a high potential energy, and then escapes into space where there is no gravity, the potential energy does not disappear. Instead, it is transformed into a different form of energy.

In space, where there is negligible gravity, the potential energy gained by the body will be converted into other forms of energy, such as kinetic energy, thermal energy, or electromagnetic energy. For example, if the body is released in space, it will start moving with a high velocity due to the conversion of potential energy into kinetic energy.

Therefore, the potential energy gained by a body at a high height does not simply disappear when it escapes into space. It is converted into other forms of energy, depending on the circumstances.
