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.


How can energy get lost?

Friction's just one way.


What happens to the 62 percent of the total energy of glucose that is not used to make ATP molecules?

The remaining energy is lost as heat due to the 2nd law of thermodynamics. According to that law, only part of the energy will transfer and the rest will be lost as heat. For example, and engine uses part of the energy for motion and the rest dissipates through heat.

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.


How do you convert elastic energy into electricity energy?

Elasticity is the ability of a material to return to its original shape after being deformed. It is not a form of energy. Mechanical energy is needed to deform the material which stores this partially as potential (mechanical) energy, some is transformed to heat energy, which dissipates, and some is lost to entropy, as in all energy conversions. When the potential (mechanical) energy is released it can be used to drive an electrical generator to produce electricity, until the material returns to its original shape.


Mechanical energy that has been 'lost' to friction isn't really lost It just is no longer in its mechanical form?

true


Where does the wasted energy from a car go?

Mostly out your radiator in the form of heat, and from braking, which heats up your brake pads. A few new cars are featuring regenerative braking to recoup that lost energy from braking. Tires also generate a lot of heat during use. Some additional energy dissipates as noise, which generates heat in the air as it travels through and fades.


Can energy be changed?

Energy can be transformed from one form to another, e.g it can be changed from electrical energy, to kinetic energy. Also energy can not be destroyed, just lost or wasted.


Is energy lost when energy changes?

Energy is never lost or destroyed.
