Key Differences
Bump generally means a slight hit or collision, or a raised spot on a surface. Whereas bumper specifically refers to a component of a vehicle intended to prevent or reduce physical damage in case of minor collisions.
Bumps can occur anywhere like on roads, skin, or even in the stock market graphs, indicating a small, often temporary, rise. On the other hand, bumpers are always associated with vehicles, particularly cars and trucks, serving a protective and safety function.
In daily language, to 'bump into someone' means to meet someone unexpectedly, while there is no such figurative usage for bumper.
Bumpers are often used metaphorically to describe something that cushions or shields in other contexts, such as "bumper profits" indicating a buffer against losses.
Bump can also describe a motion, such as in the phrase "the boat bumped against the dock," whereas bumper does not denote any type of movement.
