What is the principle of conservation of energy in an analysis of a roller coaster ride from start to finish?

The typical roller coaster starts out with a cog rail that boosts the cars to a height. Here, electrical energy is added to the system, and converted to gravitational potential energy. At the top, the coaster basically stops before starting the plunge. As the cars plunge, the potential energy is converted to the energy of motion (kinetic energy). If there are subsequent ups and downs, kinetic energy is partially traded back to potential energy and vice versa. At the end, a brake slows the cars down right at the finish, converting the kinetic energy to heat. During the ride, some friction also converts some energy to heat irreversibly.

Friction causes some of the kinetic and potential energy to be lost so the energy can't be "saved" somewhere. The only way really possible to conserve energy in a roller coaster is to have a complete vaccum where in theory there would be no friction causing energy to be lost and the roller coaster could carry on forever.

what is the role of Joule's experiment in establishing the principle of conservation of energy?
total energy IS CONSERVED and the principle of conservation of energy does hold
Where the rockets operates on the principle?
energy conservation
Which of the conservation law does not apply to an inelastic collision?
Both conservation laws are applied. The conservation of momentum and conservation of energy. However, in an inelastic collision, kinetic energy is not conserved. But total energy IS CONSERVED and the principle of conservation of energy does hold.
On what principle does calorimetry depends?
law of conservation of energy.
Energy is created nor destroyed is a statement of?
The Conservation of Energy Principle.
Hess's law is based on what principle?
conservation of energy
Can you compare the D alembert's principle and energy conservation?
no
How is the principle of conservation of energy seen in fission and fusion reactions?
Because of the principle of energy conservation the lost mass must reappear as generated energy, according to Einstein's equation E = mc²
Compare and contrast between D'alembert's principle with principle of conservation of energy?
because swag
What is the priniciple that says energy cannot be created or destroyed?
The Principle of Conservation of Energy.
Is the Ritz's combination principle to be a statement of energy conservation?
yes
What is the principle of conser vation of energy?
The principle of conservation of energy states that energy cannot be created or destroyed, but it can be transferred or transformed from one form to another. In a closed system, the total amount of energy remains constant. This principle is derived from the first law of thermodynamics, which is a fundamental principle in physics.
