What is law of conservation of energy? Analyze its application in real
life? Give 3 examples.
Answers
Answer:
⭐ The law of conservation of energy is a law of physics that states that energy cannot be created or destroyed, but only changed from one form into another or transferred from one object to another

⭐ Understanding the Law of Conservation of Energy:-
The law of conservation of energy definition emphasizes that energy is not something that can be destroyed or created. It's important to understand what that really means. It would be incorrect to say that the purpose of an experiment would be to make energy, as that would involve an effort to create something that cannot be created. Instead, energy is constantly being transformed so that it can be used. For example, solar panels don't create solar energy. They harness energy from the sun and transform it into another type of energy (electricity).
⭐ EXAMPLE:-
- Kelly ran across the room and bumped into her brother, pushing him to the floor. The kinetic energy she possessed because of her movement was transferred to her brother, causing him to move.
- Two football players collided on the field, and both went flying backward. Energy was transferred from each player to the other, sending them in the opposite direction from which they had been running.
- When kicking a football that is sitting on the ground, energy is transferred from the kicker's body to the ball, setting it in motion
Answer:
in physics and chemistry the of conservation of energy States that the total energy of the isolated system remains constant it is said to be conserve our time
