The law of conservation of energy states that energy can neither be created nor destroyed. What does “conservation” mean in this law?

Answer 1

Sample Response: The word “conservation” refers to an amount that is unchanged. The total amount of energy in the universe remains the same. The energy in the universe is in balance.

Answer 2

Law of conservation of energy

The law of conservation of energy states that energy can neither be created nor destroyed.

The word conservation means the total value of a physical quantity or parameter (such as energy, mass, linear or angular momentum). in this case, energy will remain constant in a system throughout the process which is not subject to external influence.

Formula

$K_{1}+U_{1}+P_{1} =K_{2}+U_{2}+P_{2}$

where,

$K_{1}$ is the initial kinetic energy,

$U_{1}$ is the initial internal energy,

$P_{1}$ is the initial potential energy,

$K_{2}$ is the final kinetic energy,

$U_{2}$ is the final internal energy,

$P_{2}$ is the final potential energy.

Example

For example, when we drive a car, the chemical energy of the fuel (such as petrol, diesel, gasoline), is transformed from chemical energy to heat energy and then to kinetic energy.
