Definition

1. Noun:
   • Acceleration: The rate of change of velocity of a moving object per unit of time. It describes how quickly an object speeds up, slows down, or changes direction.

Usage Examples

• Noun:
  • Xe tăng tốc với gia tốc lớn. (The car accelerated with great acceleration.)
  • Gia tốc trọng trường trên Trái Đất là khoảng 9,8 m/s². (The gravitational acceleration on Earth is approximately 9.8 m/s².)
  • Công thức tính gia tốc là thay đổi vận tốc chia cho thời gian. (The formula for calculating acceleration is change in velocity divided by time.)

Advanced Usage

• "Gia tốc góc" (Angular acceleration): The rate of change of angular velocity.
  • Gia tốc góc của bánh xe đang quay rất quan trọng trong cơ học. (The angular acceleration of a spinning wheel is very important in mechanics.)
• "Gia tốc hướng tâm" (Centripetal acceleration): The acceleration that keeps an object moving in a circular path, directed towards the center.
  • Khi ô tô vào cua, nó chịu một gia tốc hướng tâm. (When a car turns a corner, it experiences centripetal acceleration.)
• Used metaphorically for rapid development or increase:
  • Nền kinh tế đang phát triển với gia tốc cao. (The economy is developing with high acceleration/at a rapid pace.)

Variants and Related Words

• Gia tốc kế (Accelerometer) (n): A device that measures acceleration.
  • Điện thoại thông minh có cảm biến gia tốc kế. (Smartphones have an accelerometer sensor.)
• Gia tốc trọng trường (Acceleration due to gravity) (n.phr): The acceleration of an object caused by the force of gravity.
• Tăng tốc (To accelerate) (v): The verb form meaning to increase speed.
  • Xe bắt đầu tăng tốc. (The car began to accelerate.)

Synonyms

• Sự tăng tốc: The act of accelerating, speeding up. (Often used interchangeably in general contexts.)
• Tốc độ tăng: Rate of increase. (More general, not strictly physics-specific.)

Related Phrases (Collocations)

• Có gia tốc: To have acceleration.
  • Vật thể chuyển động thẳng đều không có gia tốc. (An object in uniform linear motion has no acceleration.)
• Tính gia tốc: To calculate acceleration.
• Gia tốc âm / Gia tốc giảm (Negative acceleration / Deceleration): Slowing down.
  • Phanh tạo ra gia tốc âm. (Brakes produce negative acceleration/deceleration.)

Notes

• In physics, 'gia tốc' is a vector quantity, meaning it has both magnitude and direction.
• In everyday language, it can be used more loosely to describe any rapid increase or progress, similar to the metaphorical use of "acceleration" in English.
