give and explain five examples form daily life to prove the statement energy can neither be created nor destroyed
Answers
Answer: 1) Human metabolism, the food we take gives us energy which we use to move, work, exercise, play.
2) When a moving car hits another car which is parked to make it move, energy of the moving car is transferred from the moving car to the parked car.
3) Water is used to produce electricity. Water falls from the sky, converting potential energy to kinetic energy.
Answer:
Energy is the capacity to do work and is an essential element of our daily lives. Energy is a fundamental concept of physics and all living organisms. It is a fundamental law of physics that energy can neither be created nor destroyed. Instead, it can only be transferred or changed from one form to another. The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.
Explanation:
The first example of energy that can neither be created nor destroyed is the sun's energy. The energy generated by the sun is not created or destroyed, but is instead transferred from the sun to the earth. The sun's energy is ultimately converted into light, heat, and other forms of energy.
The second example of energy that can neither be created nor destroyed is the energy of wind. Wind is a form of kinetic energy that is created from the differences in pressure between the air. The energy of the wind is merely transferred from one place to another and is not created or destroyed.
The third example is water. Water has the potential to store and release energy as it flows from one place to another. The energy of the water is not created or destroyed, but is instead transferred or converted.
The fourth example is Battery. Batteries are a perfect example of energy conversion. When a battery is charged, energy from the power source is converted to chemical energy, which can be released when the battery is discharged. No energy is created or destroyed during this process, it is merely transferred from one form to another.
The fifth example is Cooking. When we cook food, energy from the heat source is transformed into kinetic energy, which causes the food to cook. Again, no energy is created or destroyed, but instead transferred from one form to another.
