In a system the potential energy is related to forces acting between bodies inside the system. Kinetic energy of a moving body is defined as K=(1/2)*m*v^2 where m is the mass of the body and v its velocity. If no energy is transfered to or from the system then the sum of the system's kinetic and potential energy remains constant.

answer2: The universe is composed or quaternions, a real number or scalar and 3 vector numbers. Energy has these two types the potential energy is the real part and kinetic energy is the vector part, for example take gravity energy:

E = Pot + Kin = -mGm/r + mcV = -mu/r + mcV ,

where the potential gravitational energy is the scalar part and mcV is the kinetic vector energy. V is the velocity vector.

Currently Physics defines "energy as a scalar" in spite of Torque, a vector FxR with units joule or Newton -meter.
Well, kinetic energy is the energy of motion and potential energy is the energy of position
Potential Energy. Stored energy that results from the position or shape of an object.

Kinetic Energy Energy that an object has due to its motion.
History

A roller coaster train going downhill represents merely a complex case as a body is descending an inclined plane. Newton's first two laws relate force and acceleration, which are key concepts in roller coaster physics. At amusement parks, Newton's laws can be applied to every ride. These rides range from 'The Swings' to The 'Hammer'. Newton was also one of the developers of calculus which is essential to analyzing falling bodies constrained on more complex paths than inclined planes. A roller coaster rider is in an gravitational field except with the Principle of Equivalence.

Potential Energy

Potential energy is the same as stored energy. The "stored" energy is held within the gravitational field. When you lift a heavy object you exert energy which later will become kinetic energy when the object is dropped. A lift motor from a roller coaster exerts potential energy when lifting the train to the top of the hill. The higher the train is lifted by the motor the more potential energy is produced; thus, forming a greater amount if kinetic energy when the train is dropped. At the top of the hills the train has a huge amount of potential energy, but it has very little kinetic energy.

Kinetic Energy

The word "kinetic" is derived from the Greek word meaning to move, and the word "energy" is the ability to move. Thus, "kinetic energy" is the energy of motion --it's ability to do work. The faster the body moves the more kinetic energy is produced. The greater the mass and speed of an object the more kinetic energy there will be. As the train accelerates down the hill the potential energy is converted into kinetic energy. There is very little potential energy at the bottom of the hill, but there is a great amount of kinetic energy.

Theory

When the train is at the top and bottom of the hill there is not any potential or kinetic energy being used at all. The train at the bottom of the first drop should have enough energy to get back up the height of the lift hill. The "Act of Faith" in riding these amazing rides which seems more of a phenomena that is only a theory. In practices, the train never could make it back up the hill because of dissipative forces. Friction and air resistance, and even possible mid-course breaks, are dissipative forces causing the theory to be changed but not destroyed. These forces make it impossible for the train to have enough energy to make it back up the lift hill's height. In the absence of the dissipative forces the potential and kinetic energies(mechanical energy) will remain the same. Since the mechanical energy is destroyed by the forces, the first hill is always the highest.

KINETIC POTENTIAL ENERGY,

iS the ammount of energy one has, then the other is stopped and it goes down a hill or something steep.

potential energy is stored energy before the object is put into motion the higher the object is at level the more potential energy their is ;kinetic is energy in motion it is when the object is released and put into motion that the potential energy drops and kinetic rises

A thing which has energy due to its movement or motion has kinetic energy e .g a bullet emerging from a revolver.

A thing which has energy due to its position has potential energy e.g. a ball 10 meters off the ground

A Simpler AnswerA boulder sitting on the edge of a cliff has potential energy.

A boulder tumbling down the cliff has kinetic energy.

In a wider sense.......

Kinetic, of course, is meant as 'in motion'. So energy possessed by a material object when it is in motion is said to be kinetic energy. It is calculated by the formula 1/2 m v2

But potential is meant as the status or position. Potential energy is measured as the work performed in moving a unit mass from infinity to the specified position in the gravitational field. Same way, in case of electric field, electric potential energy is the work done in moving positive charge from infinity to the specified position in the electrical field. In the same manner, magnetic potential energy is the work done in moving magnetic pole from infinity to the specified position.

Any way, the formula will be different in different fields. The familiar formula for potential energy viz 'mgh' is actually the potential energy difference not the potential energy at that height or position. Here the potential energy on the surface of the earth is taken to be Zero. But actually the potential energy for a mass 'm' on the surface of earth with mass 'M' and radius 'R' is given as GMm/R2.

Potential energy is the stored energy in an object due of its position or its configuration whereas Kinetic energy is the energy which a body possesses because of its motion.
