Coasting is often used to describe a car or a bike that is moving downhill without the use of its engine. However, the word can also be used in other contexts, such as when referring to someone who is performing poorly at work but relying on past successes to maintain their position. Synonyms for coasting in this sense include slacking, resting on one's laurels, taking it easy, and riding on past achievements. Other synonyms for coasting in a sense of movement include gliding, drifting, sailing, and cruising. However, it is important to note that each of these has its own connotations and is best used in specific contexts.
