Why are bonds more like springs than like sticks?

Bonds are more like springs than sticks because they can stretch and compress, allowing for flexibility in molecular interactions. Just as springs can store energy when deformed, bonds can absorb energy during molecular vibrations or reactions. Unlike sticks, which are rigid and break under stress, bonds can adjust their lengths and angles, enabling dynamic behavior in chemical structures. This adaptability is crucial for processes like chemical reactions and molecular conformations.
