Answer:

Concept:

The energy that an object has as a result of its orientation in relation to other objects, interior tensions, electric charge, or other sources is known as potential energy. Potential energy includes the gravitational force of an object, which is defined by its mass and distance from the centre of mass of another object, the elastic elastic potential of a stretched spring, and the electromagnetic current energy of an electrical signal in an electric field. The joule, denoted by the letter J in the Internacional System of Units (SI), is the SI's energy unit.

Given:

A body's potential energy at a given height is 200j. When it just reaches the earth's surface, the kinetic energy it possesses is

Find:

find the then kinetic energy possessed by it when it just touches the surface of the earth is

Answer:

Potential energy is equal to The body's initial potential energy is 200 J. Its potential energy is turned into kinetic energy when it is released.The kinetic energy of the body equals the potential energy when it barely touches the ground.

If there is no drag and there is no vacuum, the KE when it hits the ground is the same as the PE from the altitude at which it was dropped. This is due to the fact that falling turns PE to KE. As a result, KE = 200J.
