What else can I help you with?
Mechanical energy that has been 'lost' to friction isn't really lost It just is no longer in its mechanical form?
When mechanical energy is lost to friction, it is converted into thermal energy due to the heat generated by the friction. This thermal energy dissipates into the surroundings, which is why the original mechanical energy is no longer in its mechanical form.
What is lost energy called?
Energy cannot be lost it is only converted from one state to the next.
What two ways is energy lost?
Energy is lost through heat transfer, where a portion of the original energy is converted into heat and dissipates into the surroundings. Energy can also be lost through friction, which occurs when surfaces rub against each other and generate heat, resulting in a loss of energy.
Why is the heart makes sounds?
The heart is not a perfect system and some energy dissipates in the form of sound energy. It is similar to light bulb not converting 100% energy to light; e.g. some of the energy is lost as heat and sound.
What if one form of energy is converted into another there is always some energy lost as?
When one form of energy is converted into another, some energy is lost as heat due to inefficiencies in the conversion process. This is known as the law of conservation of energy, which states that energy cannot be created or destroyed, only transformed. The lost energy typically dissipates into the surroundings, making the total amount of energy in a closed system remain constant.
How is energy permantely lost?
Energy can be permanently lost through processes such as heat transfer, friction, and radiative cooling. When energy is converted from one form to another, some of it is inevitably lost as waste heat, which cannot be used to do work and ultimately dissipates into the surroundings. This is a fundamental principle known as the second law of thermodynamics.
How can energy get lost?
Friction's just one way.
Is there a disease called short memory lost?
No there isnt. That is called Alzheimer
What is food energy lost as?
Calories in. Calories out. A calorie is just a way to measure the energy created and spent by eating. This is just a simplified answer.
An inefficient machine is said to waste energy Does this mean that energy is actually lost?
No. By wasting energy, this means that the machine is not as efficient at converting input into work as it could be. Generally the energy is converted into friction or heat by mechanical means and is counted as a loss towards viable work as it can not be utilized, but the total amount of energy is equivalent.
Why damping causw decrease in the amplitude of a vibration?
Damping in a vibrating system causes a decrease in amplitude because it dissipates energy from the system in the form of heat or sound. As energy is lost to damping forces such as friction or air resistance, the system's natural frequency is reduced, leading to smaller oscillations over time.
What happens to the other 90 percent of energy and in what form does it re-enter the environment?
The other 90 percent of energy is typically lost as heat energy during energy transformations in an ecosystem. This heat energy eventually dissipates into the environment, contributing to the overall increase in entropy.
