📖 Cultural Story
Derived from Latin 'conservatio', used since the 14th century. Gained prominence in the 20th century with environmental movements advocating for natural resource protection.
Meaning 2：law of conservation (conservation)
conservation
/ˌkɒnsəˈveɪʃn/

law of conservation
➕
/lɔː əv ˌkɒnsəˈveɪʃn/
n.
A scientific principle stating that a specific measurable property (such as energy or mass) remains constant in an isolated system over time.
📘 Details & Usage
📖 Example
In our physics class, we were asked to explain the conservation of energy using the example of a rolling ball.
In our physics class, we were asked to explain the principle that energy cannot be created or destroyed, only transformed, using the example of a rolling ball.
🔗 Collocations
