How do gravity and potential energy work together to give you a great ride on a roller coaster?
the gravitational potential energy of a roller coaster is equal to two things. Not only is it equal to the gravitational potential energy, it is also equal to the kinetic energy at the lowest point of the coaster. the gravitational potential energy can be calculated as: m*g*h where m is mass (kilograms), g is gravity (9.8 m/s^2), and h is height (metres).d the kinetic energy at the bottom of the coaster can be calculated as (m*v^2)/2 where m is mass (kilograms), v is velocity (metres/second).
How do the roles of potential and kinetic energy differ between the newer catapult launched coasters and the older style of roller coaster?
In some newer coaster designs, a catapult launch sets the train in motion. There are several sorts of catapult launches, but they all basically do the same thing. Instead of dragging the train up a hill to build up potential energy, these systems start the train off by building up a good amount of kinetic energy in a short amount of time.
Where does a roller coaster have the lowest amount of kinetic energy?
at the top of the first hill, just before the first drop
Can kinetic energy be changed back to potential energy?
Kinetic and Potential EnergyHistoryA 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 EnergyPotential 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 EnergyThe 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.TheoryWhen 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 quantity is the sum of the kinetic energy and all forms of potential energy in a system?
the total energy U. If there is no work done on the system, Uint= KE+PE
What is usually the highest point on a roller coaster?
The top of the first hill. This is where the coaster has its greatest amount of potential energy which is converted to kinetic energy as it moves along the track.
Where is the greatest amount of potential and kinetic energy in a roller coaster?
If it is a rollercoaster that has a first drop hill, the roller coaster has the greatest kinetic energy at the bottom of that drop. If it is magnetically launched, the kinetic energy is probably greatest immediately after the launch. However, there are cases where these statements may not be true. (i.e. a drop right after a magnetic launch)The energy is the greatest at the bottom of a drop, before some is translated back into potential energy as the car climbs the next rise.
A roller coaster going down the first drop is an example of?
At the top of the first hill, the coaster car has stored the maximum amount of potential energy. This is shown in the equation for potential energy, PE=mgh, where h is the height. The greater the height, the greater the potential energy. During the drop, potential energy is being converted into kinetic energy. The equation for kinetic energy is KE=(1/2)mv^2, where v is the velocity of the coaster car. The faster the car is going, the greater the kinetic energy. So as the car goes faster, the kinetic energy grows. But as the car goes down, h is getting lower, lowering the potential energy.
Total amount of potential and kinetic energy?
Total Energy = Potential + Kinetic TE=PE+KE
Where on a roller coaster is there equal amounts of potential energy and kinetic energy?
There would be equal amounts of kinetic and potential energy at the middle of a drop, because the potential energy would have lost half of it's amount and the kinetic energy would have gained that amount but none else so far. Pretty sure thats all right, 🖒
Is it possible to have more kinetic energy than potential energy?
No, because potential energy is the amount of energy that COULD be used, while kinetic energy is the amount of energy that IS being used.
Where does a roller coaster have the least kinetic energy?
At the tallest point on the track. Potential energy is given by U(Which is potential energy) = mass times height time gravitational constant. You can't change the gravitational constant, or the mass of the roller coaster car. So you have to change the height. PE=mgh so more the height and the mass the more PE
Amount of kinetic and potential energy of an object?
Mechanical Energy :)

What two things do potential and kinetic energy need to gain more energy?
Well, basically, the higher an object is above the ground, the more potential energy it has. For kinetic energy, the amount of energy depends on the amount of force.
What is amount of energy an object has in it?
It is the sum of the potential and kinetic energies
What three types of energy from a roller coaster are added together to equal the total amount of original potential energy?
These would be the Linear Kinetic Energy due to the forward velocity of the car; The Rotational Kinetic Energy of the rotating wheels and the Thermal or Heat Energy due to the various frictional forces on the car.
