ข้อผิดพลาดที่พบบ่อย:
Learners often use "velocity" and "speed" as perfect synonyms. In physics, "velocity" usually includes direction (for example, 10 m/s north), while "speed" is only how fast something moves, without direction.
ความหมาย
speed of something in a direction
คำที่ใช้ร่วมกัน
high velocity
|average velocity
|constant velocity
|initial velocity
|escape velocity
|terminal velocity
คำพ้องความหมาย
speed (General term for how fast something moves; does not always highlight direction the way the physics term "velocity" does.)
คำตรงข้าม
rest (In physics, an object at rest has zero velocity, so it is the direct opposite state of having a nonzero velocity.)
หัวข้อ

คำจำกัดความ
How fast something moves in a certain direction, for example meters per second.
The rate at which something changes its position in a particular direction, usually measured as distance traveled per unit of time.

ข้อผิดพลาดที่พบบ่อย:
Learners sometimes assume this sense is only scientific. In business, technology, and everyday writing, "velocity" can be used more loosely to mean the fast pace of work or change, not just physical movement.
ความหมาย
high speed of change or action

คำพ้องความหมาย
pace (Emphasizes the general speed or rhythm of activity; less technical-sounding than "velocity" and more common in everyday speech.)
คำตรงข้าม
slowness (Describes when actions or changes happen at a low speed, the opposite of high velocity.)

คำจำกัดความ
The very fast speed of an action or change, for example how quickly a company works or how fast technology changes.
Great speed or rapidity with which something happens or develops, especially in business, technology, or social change.

คำพ้องความหมาย
intensity (Colloquial way musicians may refer to how strong a note is played; "velocity" is the precise technical term in MIDI data.)
คำตรงข้าม
softness (Lower velocity values produce softer notes, so softness contrasts with high-velocity, loud or aggressive playing.)

คำจำกัดความ
In computer music, a number that shows how fast and hard you press a key or pad, often used to set how loud the note is.
In digital music and MIDI systems, a numerical parameter that represents the speed and force of a key or pad strike, typically used to control the loudness and expressiveness of a note.
