event
1
two moving things hitting each other
An event when two or more things that are moving hit each other.
用法模式：
a collision between [thing] and [thing]
常见错误：
Learners often use "accident" when they should use "collision". "Accident" can be any bad event, but "collision" specifically means things hit each other. Also, learners sometimes say "collision of two cars"; the more natural pattern is "a collision between two cars" or "a collision with another car".
近义词
crash (Often used especially for vehicles and sounds more dramatic or sudden, while "collision" is a bit more neutral and formal.)
反义词
near miss (Describes a situation where an accident or collision almost happens but is successfully avoided.)

2
strong conflict or clash
A serious fight or strong disagreement between people, groups, or ideas.
用法模式：
a collision between [groups/ideas/interests]
常见错误：
Learners sometimes use "collision" for any small disagreement. It is better used for serious or direct conflicts, especially between big groups, strong interests, or very different ideas. For small, everyday problems, words like "argument" or "disagreement" are more natural.
近义词
clash (Very similar meaning; "clash" is slightly more common in everyday speech, while "collision" often sounds more formal or dramatic.)
反义词
harmony (When there is harmony, people or ideas fit together well, which is the opposite of the strong opposition suggested by "collision".)

short, forceful interaction in physics
In physics, a very short and strong meeting between objects that changes how fast or in what direction they move.
用法模式：
a collision between [particle/body] and [particle/body]
常见错误：
Learners may think a "collision" in physics always means damage or breaking. In physics, it only means a brief, strong interaction that changes motion; the objects can stay unchanged in shape, especially in ideal models.
近义词
interaction (In physics this can be a broader term; a "collision" is a specific type of short, strong interaction that changes motion.)
反义词
non-interaction (Describes a situation in physics where bodies do not significantly affect each other, the opposite of a strong, motion-changing collision.)

simultaneous signals on a network
In computer networks, a problem that happens when two or more devices send data at the same time and the messages hit each other and cannot be read clearly.
用法模式：
a collision on [network/channel]
常见错误：
Learners may confuse a network "collision" with a physical break in the cable or complete loss of connection. A collision is a timing problem where signals overlap; the network and hardware usually detect it and resend the data.
近义词
data conflict (A more general term; "collision" is the standard technical word for this specific problem on shared communication channels.)
反义词
successful transmission (Describes data being sent and received correctly without interference, the opposite of a collision event on the network.)
