Question: Which of the following statements about the rotatory motion along a circular path is true?...
Which of the following statements about the rotatory motion along a circular path is true?
A
Linear velocity is uniform when angular velocity is uniform
B
Magnitude of acceleration is constant
C
Acceleration is directed along the tangent to the circular path
D
None of the above statements is correct
Answer
Magnitude of acceleration is constant
Explanation
Solution
Direction of linear velocity change continuously, thus linear velocity is not constant but magnitude of centripetal acceleration is constant
