Answer 1

Sure. This happens when an object falls down. Its potential energy will decrease, and its kinetic energy increases.

Answer 2

There are many forms of potential energy. The classic physics homework problem relates gravitational potential (mass*gravitational constant*height above reference) aka PE=mgh. As an object falls, it gets closer to the reference, and has less potential energy (less distance to fall). This lost potential has been turned into another form of energy. In the classic physics problem, that energy is assumed to be entirely kinetic. The equation for kinetic energy is .5*mass*velocity*velocity (KE=.5mv2). Using these two equations, a problem can be solved involving an object falling (losing potential energy) and converting that potential energy into kinetic, and in the end, determining the speed of the falling object.

Answer 3

Kinetic and Potential Energy

History

A roller coaster train going down hill 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

Answer 4

Potential energy is energy that is stored and has the potential to do something, for instance a stretched elastic band that has not yet been released, or a rock teetering on the edge of a cliff but has not yet fallen.

Kinetic energy is the energy of motion. So when the elastic band releases, or the rock falls, the stored energy now becomes kinetic energy. In a way, potential energy is theoretical in that it really only exists when it becomes kinetic energy through some kind of movement or change.

Therefore, potential energy is converted to kinetic energy essentially through some sort of movement.

Answer 6

An object has potential energy if it has been pushed into a certain position, against a certain type of force (a so-called "conservative force"). The potential energy will automatically be "released" when the object goes back to a lower-energy position (meaning, in this case, less potential energy); in that case, the potential energy will quite often be converted into kinetic energy, since the force tends to accelerate the object. One example is when an object in a high position (and which therefore has gravitational potential energy) falls down. Another example is when a spring is released.
