What is the difference between negligence and omission?

Negligence refers to a failure to take reasonable care, resulting in harm or damage to another person, often involving an action that should have been taken but wasn't. Omission, on the other hand, specifically refers to the failure to act when there is a duty to do so, which can lead to negative consequences. While negligence encompasses both actions and omissions that lead to harm, omission focuses solely on the lack of action in situations where action is required. In legal contexts, both concepts can lead to liability, but they address different aspects of responsibility.
