Question

The graphs shows, angular velocity as a function of time. In which one is the magnitude of the angular acceleration constantly decreasing?

• A.

  

• B.

  

• C.

  

• D.

  

Answer 1

The Correct Option is D

The correct option is (D):

From the first graph, it is evident that as time goes on, the value of Omega (angular velocity) decreases.

Angular velocity is a vector number that indicates the angular speed or rotational speed of an object and the axis around which the object is revolving. The amount of change in the particle's angular displacement over time is known as angular velocity. The angular velocity vector's course is vertical to the plane of rotation, as indicated by the right-hand rule.

Formula for Angular Velocity
\(w=\frac{d \Theta}{dt}\)

Where,
The change in angular displacement is denoted by dθ .
The shift in time t is represented by dt.
