Learner examples

Common mistake:
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".
Meaning
two moving things hitting each other
Collocations
car collision
|head-on collision
|minor collision
|traffic collision
|fatal collision
|rear-end collision
Synonyms
crash (Often used especially for vehicles and sounds more dramatic or sudden, while "collision" is a bit more neutral and formal.)
Antonyms
near miss (Describes a situation where an accident or collision almost happens but is successfully avoided.)

Definition
An event when two or more things that are moving hit each other.

Usage pattern:
a collision between [groups/ideas/interests]

Learner examples

Common mistake:
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.
Meaning
strong conflict or clash
Collocations
collision of interests
|collision between cultures
|collision between theory and practice
|inevitable collision
Synonyms
clash (Very similar meaning; "clash" is slightly more common in everyday speech, while "collision" often sounds more formal or dramatic.)
Antonyms
harmony (When there is harmony, people or ideas fit together well, which is the opposite of the strong opposition suggested by "collision".)

Definition
A serious fight or strong disagreement between people, groups, or ideas.

ütközés

Usage pattern:
a collision between [particle/body] and [particle/body]
In an elastic collision, the total kinetic energy of the system is conserved.
Rugalmas ütközés során a rendszer teljes mozgási energiája megmarad.
The experiment measures the angle after the collision between the two particles.

Physicists study high-energy collisions inside the particle accelerator.
The simulation models collisions between gas molecules in a closed container.
Momentum is always conserved in a closed system during a collision.
Learner examples
In physics class we learned about elastic and inelastic collision.
Fizikaórán tanultunk a rugalmas és a rugalmatlan ütközésről.
The collision changes the speed of both objects.
Az ütközés mindkét test sebességét megváltoztatja.
Scientists study collisions of particles in large machines.
Energy can move from one object to another in a collision.
A collision only takes a very short time but has a big effect.
Common mistake:
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.
Meaning
short, forceful interaction in physics
Collocations
elastic collision
|inelastic collision
|particle collision
|perfectly elastic collision
|head-on collision (in physics)
Synonyms
interaction (In physics this can be a broader term; a "collision" is a specific type of short, strong interaction that changes motion.)
Antonyms
non-interaction (Describes a situation in physics where bodies do not significantly affect each other, the opposite of a strong, motion-changing collision.)
Themes
science
|physics
|technology
Definition
In physics, a very short and strong meeting between objects that changes how fast or in what direction they move.
In physics, a short-duration interaction between bodies during which they exert large forces on each other and their velocities or directions change, often with an exchange of energy or momentum.

Usage pattern:
a collision on [network/channel]
The network adapter uses collision detection to know when it can send data.

Ethernet collisions were common in older hub-based networks.

Reducing the size of the collision domain improved performance.
Learner examples
Old Ethernet networks had many collisions on the cable.
A régi Ethernet-hálózatokban sok ütközés történt a kábelen.
A collision means two computers send data at the same time.
A hálózati ütközés azt jelenti, hogy két számítógép egyszerre küld adatot.
After a collision, the devices wait and then try again.
Too many collisions can make the network very slow.
The software can show how many collisions happen each day.
Common mistake:
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.
Meaning
simultaneous signals on a network
Collocations
data collision
|packet collision
|Ethernet collision
|collision detection
|collision domain
Synonyms
data conflict (A more general term; "collision" is the standard technical word for this specific problem on shared communication channels.)
Antonyms
successful transmission (Describes data being sent and received correctly without interference, the opposite of a collision event on the network.)
Themes
technology
|computing
|communication
Definition
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.
In computing and networking, an event in which two or more devices try to send data on the same channel at the same time, causing the signals to interfere with each other so that the data cannot be read correctly.
