increase in speed of movement
The way something that is moving starts to go faster.
Schemat użycia:
the acceleration of [something moving]
Częsty błąd:
Learners often confuse 'speed' with 'acceleration'. 'Speed' is how fast something is moving; 'acceleration' is the change in speed, usually from slower to faster. Another mistake is using a verb form like *'accelarate'* instead of the correct verb 'accelerate'.
Synonimy
speed-up (Informal and general; describes getting faster but is less often used for precise physical motion.)
Antonimy
deceleration (Specifically refers to a decrease in speed, the opposite change to acceleration.)

Przykłady dla uczących się
- The bus’s acceleration pushed me back in my seat.

process becoming faster or more intense
When some activity or change starts to happen faster than before.
Schemat użycia:
the acceleration of [process/change]
Częsty błąd:
Learners sometimes use 'acceleration' when 'growth' alone is better. 'Growth' is the increase itself; 'acceleration of growth' means the growth is happening faster than before, not just that it exists.
Synonimy
intensification (Stresses things becoming stronger or more extreme, not only faster, and often sounds more formal.)
Antonimy
slowdown (Commonly used for business and social processes when they become slower instead of faster.)

physics rate of change of velocity
In physics, a measure of how fast the speed and direction of something change in a certain time.
Schemat użycia:
the acceleration of [object] is [value]
Częsty błąd:
Learners often think acceleration only means 'speeding up'. In physics, acceleration also includes slowing down and changing direction, because it is any change in velocity.
Synonimy
rate of change of velocity (A descriptive technical phrase often used in explanations and textbooks rather than everyday speech.)
Antonimy
zero acceleration (Describes the absence of any change in velocity, the technical opposite condition.)

Przykłady
- Under constant acceleration, the object’s velocity increases by the same amount each second.
- According to Newton’s second law, acceleration is proportional to the net force acting on a mass.
- The experiment measured the angular acceleration of the rotating disk.
- Near Earth’s surface, the standard acceleration due to gravity is approximately 9.8 m/s².
- Plotting velocity against time allows you to calculate the object’s acceleration.
Przykłady dla uczących się
- In this problem, you must find the acceleration of the ball.
- The graph shows how the acceleration changes over time.
- If the force is bigger, the acceleration is bigger too.

how quickly a vehicle speeds up
How fast a car, bike, or other vehicle can start going faster.
Schemat użycia:
[vehicle] has good/poor acceleration
Częsty błąd:
Learners sometimes say *'strong speed'* or *'big speed'* when they mean that a car can speed up quickly. In this context, 'acceleration' or 'pickup' are the natural choices.
Synonimy
pickup (Informal; commonly used in car talk to describe how quickly a vehicle responds when you press the pedal.)
Antonimy
sluggishness (Describes slow, weak response when speeding up, the opposite of lively acceleration in vehicles.)

speeding up computing tasks
In computers, making programs or tasks run faster, often with special parts or code.
Schemat użycia:
hardware/software acceleration of [task/process]
Częsty błąd:
Learners may confuse 'acceleration' here with 'overclocking'. Overclocking is one specific way to make a chip faster, while acceleration can also come from using different hardware units or better code.
Synonimy
optimization (Focuses on improving efficiency in general; not all optimization is about speed, while acceleration specifically stresses faster execution.)
Antonimy
bottleneck (Refers to a part of a system that slows everything down, working against acceleration.)

students moving through school faster
In schools, letting a student study faster than normal, for example by skipping a grade.
Schemat użycia:
academic/grade acceleration for [student/group]
Częsty błąd:
Learners may confuse 'acceleration' with simply 'extra classes'. Acceleration means moving through the official program faster, not just adding more lessons at the same level.
Synonimy
advancement (More general; can mean any move to a higher level, not specifically moving faster through school.)
Antonimy
retention (In education, keeping a student in the same grade for longer, the opposite of moving them ahead more quickly.)
