Angular velocity is measured in:
কৌণিক বেগের একক কী?
Practice MCQ for SSC, UPSC, RRB Exams
A. \(m/s\)
A. \(m/s\)
B. \(m^2/s\)
B. \(m^2/s\)
C. \(rad/m\)
C. \(rad/m\)
D. \(rad/s\)
D. \(rad/s\)
Correct Answer: D
সঠিক উত্তর: D
Explanation
ব্যাখ্যা
Angular velocity
represents the rate of change of angular displacement with respect to time.
It is represented by the symbol:
\(\omega\)
The formula of angular velocity is:
\(\omega=\dfrac{\theta}{t}\)
Where:
\(\theta\) = angular displacement measured in radians \((rad)\)
\(t\) = time measured in seconds \((s)\)
Therefore, the unit of angular velocity is:
\(\dfrac{rad}{s}=rad/s\)
Important:
Linear velocity is measured in \(m/s\), while angular velocity is measured in \(rad/s\).
কৌণিক বেগ (Angular velocity)
হলো সময়ের সাথে কৌণিক সরণের পরিবর্তনের হার।
এটি সাধারণত এই চিহ্ন দ্বারা প্রকাশ করা হয়:
\(\omega\)
কৌণিক বেগের সূত্র:
\(\omega=\dfrac{\theta}{t}\)
যেখানে:
\(\theta\) = কৌণিক সরণ, যার একক রেডিয়ান \((rad)\)
\(t\) = সময়, যার একক সেকেন্ড \((s)\)
অতএব কৌণিক বেগের একক:
\(\dfrac{rad}{s}=rad/s\)
গুরুত্বপূর্ণ:
সরলরৈখিক বেগের একক \(m/s\), কিন্তু কৌণিক বেগের একক \(rad/s\)।
