When a pendulum swings the size of the swing gradually reduces with time until the pendulum stops explain how this can be possible if energy is conserved?
Energy is conserved in an isolated system, meaning since energy cannot be created or destroyed, the amount of energy in the system is the same. The point is, what is the 'system' in a certain scenario. Even if the pendulum was in an isolated room, that doesn't mean the pendulum will swing forever, because energy is constsntly lost to the environment, due to the friction with the air. But while energy is lost from the pendulum, energy is gained by the surrounding air molecules (also isolated), and thus energy in the system is conserved. Eventually the pendulum's kinetic energy will be zero, having lost too much to be able to make it move.
When heat is converted to another form of energy there is loss of energy?
The law of conservation of energy states that energy cannot be created or destroyed, so the total energy in an isolated system remains constant. Since no machine is 100% efficient, it may seem that energy is being lost, but the "lost" energy is just converted to a different form.
What type of energy is lost energy on energy?
energy can not be lost it can only be transported into other things
What can cause loss of energy?
According to the laws of thermodynamics, energy can never be "lost" or "made". Energy, in a closed system, is always constant. Energy can however be "lost" to the environment, for instance by friction. If you drag a box over the floor, some of the energy you are putting into moving the box is being "lost" to the environment by friction between the box and the ground (and a very small amount to air friction). You could therefor say that friction is a cause for "loss" of energy.
When energy is transformed is some lost or gained?
there is an increase in entropy in the universe.
What energy that is lost doing work is lost as what type of energy?
Final end of all energy lost is thermal energy. Thermal energy is the least valuable energy. The concept of entropy is rely on the loss of working capability of the system to the thermal energy. In general, the term for thermal energy lost can be called waste heat.
Why is energy pyramid never inverted?
No, it is not possible. In a particular energy pyramid, no additional energy enters the system, and energy is lost to the environment at every level.

Is energy lost when energy changes?
Energy is never lost or destroyed.

When was Lost Energy created?
Lost Energy was created in 2008.
What is the ultimate fate of energy flowing through a biological community?
the sun through photosynthesis Nope. The ultimate fate of energy flowing through a biological system is that it will be lost. This is due to conversion to non-recyclable forms, specifically heat. Below is the cyclical flow of energy in a system but at every step a large amount of energy is lost through metabolic activity. Sun(energy entering the system) > Primary producers > Herbivores > Carnivores > Primary producers > Herbivores > Carnivores etc.
When people say energy is lost what do they mean?
The energy in a closed system is constant, which is the principle of Conservation of Energy, but in machines the amount of useful energy coming out is less than the amount going in. This is explained by lost energy. In a petrol engine the lost energy comes out in the form of heat because the engine block is hot, which happens because of friction in the bearings but also because the gas in the cylinder has to be at a high temperature and pressure.
How is calorimetry related to the law of conservation of energy?
The Law of Conservation of Energy states that energy is neither created nor destroyed but remains constant in a given system. Therefore, wouldn't calorimetry make use of it because the energy gained/lost by the water would cancel out the energy lost/gained by the substance and result in no change overall?

When is total mechanical energy conserved?
In theory, in a closed frictionless system. In practise, never because some energy is always lost in the form of heat or sound.
How does kenetic energy stop and go by friction?
Let's get started! An object in motion possesses kinetic energy and to bring the object to a stop this kinetic energy must be removed. ... A mechanical brake applies a friction force to convert the kinetic energy of the vehicle into thermal energy which then dissipates into the atmosphere.
