What is the Law of Conservation of Energy?

[henry]

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed. For instance, in a pendulum, potential energy converts to kinetic energy and vice versa during its swing.

 

[BarryRaymo]

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed or transferred from one form to another. The total amount of energy in a closed system remains constant, even though energy may change forms—for example, from kinetic to potential or to heat.

 

[SkyDrifter]

The Law of Conservation of Energy refers to the fact that energy simply changes form not that it is lost. Potential energy is converted to kinetic energy and vice versa just like a swinging pendulum.

 

[Jone]

According to the law, no power can be created or lost in a closed system - it can only be transformed into some different form (e.g., kinetic 0 potential) but the sum remains the same.

 

[duke]

The Law of Conservation of Energy means energy can’t be created or destroyed, it only changes from one form to another. For example, in a pendulum, potential energy turns into kinetic energy as it swings.

 

[danisjohn]

The Law of Conservation of Energy states that energy cannot be created or destroyed; it can only change from one form to another. The total energy in a closed system remains constant, though it may transform between kinetic, potential, thermal, or other forms.

 

[nikhilrajoria]

According to the law, energy cannot be created or destroyed within an isolated system, it can only be changed or changed. Therefore, the net energy of a closed system does neither change with time, but its appearance ( Мексиica inc. (n.d., 12), might change.

 

[Robert Willian]

According to this law, the energy is can not bw created ot destroyed with in a system It can change only one form to another form.

 

[Jacks will]

According to the law of conservation of energy, in a closed system no energy can be created or taken away, all it can do is to transform but the overall amount always remains the same (transforming the potential energy into kinetic or the chemical energy into thermal energy). It is a principle of physics, or of the work of many engineers.

 

[nia]

The law of conservation of energy says that energy can’t be created or destroyed, it only changes from one form to another. For example, a pendulum’s potential energy turns into kinetic energy as it swings.

 

[robbin]

The Law of Conservation of Energy states that energy cannot be created or destroyed; it can only be transformed from one form to another. The total energy in a closed system always remains constant. For example, chemical energy can convert to heat or motion, but the overall amount stays the same. This principle is fundamental in physics and explains how energy behaves in all processes.

 

[david01]

According to the law of conservation of energy, energy is neither is created nor destroyed, in an isolated system. It changes its form to another form.
