Question

What is the definition of Work, Kinetic Energy, Potential Energy, and Mechanical Energy. ​

Answer 1

Answer:

Work:activity involving mental or physical effort done in order to achieve a purpose or result.

Kinetic Energy:energy which a body possesses by virtue of being in motion.

Potential Energy:the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.

Mechanical Energy:In physical sciences, mechanical energy is the sum of potential energy and kinetic energy. It is the macroscopic energy associated with a system. The principle of conservation of mechanical energy states that if an isolated system is subject only to conservative forces, then the mechanical energy is constant.

Mechanical energy:

In physical sciences, mechanical energy is the sum of potential energy and kinetic energy. It is the macroscopic energy associated with a system. The principle of conservation of mechanical energy states that if an isolated system is subject only to conservative forces, then the mechanical energy is constant.

Potential energy:

To summarize, potential energy is the energy that is stored in an object due to its position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height.

Kinetic energy:

In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.

Work:

In physics, work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form, it is often represented as the product of force and displacement
