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

What is the energy transfer while Jumping?

When jumping, the energy transfer involves converting potential energy into kinetic energy. Initially, the jumper has high potential energy due to their raised position. As they jump, this potential energy is converted into kinetic energy as they move upwards and forwards. Some energy is also lost as heat due to air resistance and friction with the ground.


What is the relationship between electricity and potential or kinetic energy?

Electricity is a form of energy that can be converted into either potential energy, which is stored energy, or kinetic energy, which is energy of motion. The relationship between electricity and potential or kinetic energy is that electricity can be used to create or transfer these types of energy.


How are potential and kinetic related or connected in terms of their properties or characteristics?

Potential and kinetic energy are related in that they are both forms of energy that an object can possess. Potential energy is the energy stored in an object due to its position or condition, while kinetic energy is the energy of motion. When potential energy is converted into kinetic energy, the object is in motion. This relationship between potential and kinetic energy demonstrates the transfer and transformation of energy within a system.


When is potential energy transfer into kinetic energy?

Potential energy is transferred into kinetic energy when an object moves and its height decreases. As the object falls, potential energy due to its height gets converted to kinetic energy of its motion. This transfer occurs in processes like free fall, a roller coaster's descent, or an object sliding down a slope.


How does potential energy transfer to kinetic energy?

Potential energy is converted to kinetic energy when an object transitions from a higher position to a lower position in a gravitational field. As the object falls, potential energy is converted into kinetic energy, increasing the object's speed. The total energy of the system remains constant, with the initial potential energy being transformed into kinetic energy.

How do you tell if an energy transfer is kinetic or potential?

An energy transfer is kinetic if it involves movement of an object, like an object speeding up or slowing down. It is potential if it involves stored energy that can be released later, like an object held at a height that can fall due to gravity.

Describe the conversions between potential and kinetic energy that occur when you shoot a basketball in a basket?

When the ball is positioned in your hands it has full potential energy. As you move and the ball is thrown at the basket, the potential energy is converted to kinetic energy, by the transfer of kinetic energy from your arms, to your hands, to the ball. When the ball hits the basket some of its kinetic energy was converted into potential energy and then back into kinetic energy as it hit the ground.
