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
Kinetic energy can turn into potential when an object goes fast and then there is a part where there is too much friction or a part is to high , that is where it kind of stop (potential) , but if it continues going it turns into kinetic all of a sudden. A good example is where you roll a marble and there is a high hill , the marble may not make it so it turns into potential if someone pushes it or it burly continues moving to a part where there is a part that it goes down (it goes fast because of gravity).
I hope that answers your question :-)
Most of the kinetic energy will have turned into potential energy - all of it, if there is no friction.Most of the kinetic energy will have turned into potential energy - all of it, if there is no friction.Most of the kinetic energy will have turned into potential energy - all of it, if there is no friction.Most of the kinetic energy will have turned into potential energy - all of it, if there is no friction.
Potential energy (turned into kinetic energy to drive the turbines), (turned into electrical energy by the turbines). Note the original source of this energy is the Sun (nuclear fusion).
Stored energy can change into moving energy by transfering energy from potential energy to kinetic energy
1) Kinetic energy being turned back into potential energy. Look at a child on a swing. As the swing lowers (and they speed up), that's potential to kinetic. As the swing reaches its peak and stops, that kinetic to potential. 2) Burning is chemical energy being turned into heat and light. 3) In the Sun, nuclear fusion releases energy into heat and light.
Potential energy and kinetic energy. mechanical energy is the energy of motion(kinetic energy)or the potential of motion(potential energy) so i would say-kinetic and potential energy
Potential energy being turned into kinetic energy
kinetic,potential,light energy
The two main forms of energy are Kinetic energy and Potential Energy. Kinetic energy is motion energy. Potential energy is energy stored in matter.
It is the sum of potential and kinetic energy.
Gravitational potential energy to kinetic energy
There are two main types of energy which is kinetic and potential energy.. Kinetic energy is an energy associated with motion.. while the potential energy is an energy stored with the position of an object, or its chemical composition.
Mechanical Energy= Potential energy+ Kinetic energy, so for the mechanical energy to be equal to be potential energy, the kinetic energy must be 0.
