Law of Conservation of Energy
What is Energy?
The ability of a body to do work is called energy.
State the Law of Conservation of Energy?
Law of conservation of energy states, that foe a closed system the total energy of the system is always conserved.
What are some Examples of the Law of Conservation of Energy?
Various examples explaining the law of conservation of energy include,
- Hydroelectric power plants convert potential energy to electrical energy.
- The loudspeaker converts electrical energy into sound energy.
- An electric motor converts electric energy into mechanical energy, etc.
Who Discovered the Law of Conservation of Energy?
Julius Robert Mayer was credited with the discovery of the law of conservation of energy.
Which Types of Energy can be seen when a Block Slides Down a Slope?
When a block slides down a slope, potential energy is converted into kinetic energy.
Give an Example where Potential Energy is Converted into Kinetic Energy.
In rocket propulsion, the chemical potential energy of the fuel is converted into kinetic energy of the exhasust gases which provide the required upthrust to the rocket.
Law of Conservation of Energy
Law of Conservation of Energy is the most fundamental law of physics which states that “Energy can neither be created nor be destroyed it can only change from one form of the energy to another form of the energy.” It is the fundamental law of Physics that governs various processes in our environment.
Before learning deeply about the Law of Conservation of Energy we must know about Energy. Energy is the capacity of the object to do work, It is a physical quantity that allows an object to do different types of work.
