A straightener and curling wand both use heat energy to style hair. According to the law of conservation of energy, energy cannot be created or destroyed, but only transferred from one form to another. When these styling tools generate heat to change the structure of hair, the energy used is converted from electrical energy to heat energy, showcasing the conservation of energy principle.

How does Noether's theorem relate to the conservation of energy?
Noether's theorem states that for every symmetry in a physical system, there is a corresponding conservation law. In the case of energy conservation, the theorem shows that the symmetry of time translation (the laws of physics remain the same over time) leads to the conservation of energy. This means that energy cannot be created or destroyed, only transformed from one form to another.
What is the significance of the delta PE in the context of energy conservation?
The significance of the change in potential energy (delta PE) in the context of energy conservation is that it represents the amount of energy that is converted between potential and kinetic energy in a system. This change in potential energy is important because it shows how energy is transferred and conserved within a system, helping to maintain the overall energy balance.
How does Einsteins equation Emc2 support the law of conservation of energy?
If you consider mass and energy to be equivalent and interchangeable, it does not conflict with the law of conservation of energy. E=mc2 states that energy is mass and mass is energy, so it does not disprove the law of conservation of energy.
What does your observation show on the manner in which energy is transfered?
My observation shows that energy is transferred through various mechanisms such as conduction, convection, and radiation. The manner in which energy is transferred depends on the nature of the system and the medium through which it travels. Understanding these mechanisms is crucial for studying heat transfer and energy conservation processes.
What is the first law of thermodynamics equation and how does it relate to the conservation of energy in a thermodynamic system?
The first law of thermodynamics equation is: U Q - W. This equation states that the change in internal energy of a system is equal to the heat added to the system minus the work done by the system. This equation relates to the conservation of energy in a thermodynamic system because it shows that energy cannot be created or destroyed, only transferred between different forms (heat and work) within the system.
What law states that energy cannot be created or destroyed?
Law of energy conservation. It shows that energy cannot be created or destroyed

Can mass be transformed into energy and vice versa and if so why does this not follow the conservation of mass and energy?
Transformation of energy does follow the conservation of mass and energy. When a body gains potential energy, it loses kinetic energy and viceversa. Therefore total energy always remains constant.
What equation shows conservation of both mass and charge?
The equation that shows conservation of both mass and charge is the continuity equation, ∂ρ/∂t + ∇⋅J = 0, where ρ is the charge density and J is the current density in an electromagnetic field. This equation states that the rate of change of charge density plus the divergence of the current density must equal zero, implying that charge is conserved locally. Additionally, in nuclear reactions, mass-energy equivalence (E=mc^2) relates the conservation of mass and energy.

Can I build a roller coaster that shows Newton's Three Laws of Motion energy transformation transfer of energy and conservation of energy?
Every roller coaster demonstrates all of those. The challenge is not in how to build it.The challenge is in how to watch it run and identify each of those principles in action.

Law of conservation is what?
There are two laws of conservation. One is the law of conservation of mass, which says mass can neither be created or destroyed, only changed in form. The other is the law of conservation of energy, which says energy can neither be created or destroyed, only changed in form. These laws, formulated in the 18th & 19th century, are still used to solve physics and engineering problems today, however they are now known not to be entirely true. Einstein's theory of relativity shows that mass can be converted into energy. Nuclear bombs do this. E = mc2 means in a nuclear reaction the amount of energy created (E) is equal to the mass (m) times the speed of light (c) squared.
