Systems

The video introduces the concept of conservation laws, using Richard Feynman's analogy of a child playing with blocks to explain how certain quantities in science remain constant. It discusses the definition of a system as a collection of objects separated from their environment, emphasizing that whatever is inside a closed system is conserved. The video also explores different types of conservation, such as energy, charge, and momentum, and uses a pulley system as an example to illustrate these ideas. The importance of identifying systems and understanding their properties is highlighted, concluding with a recap of the key concepts.

What types of quantities can be conserved within a system?

How do we treat an object that has no internal structure in a system?
