Physics 2012 JAMB Past Questions - Question 10: An object moves in a circular path of radius 0.5m with a speed of 1ms-¹ What is its angular velocity?
Choose the correct answers from the options given.
A:
B:
C:
D:
Correct Answer
C
Explanation
To find the angular velocity of an object moving in a circular path, we can use the formula:
Angular velocity (ω) = v / r
where v is the linear velocity and r is the radius of the circular path.
In this case, the linear velocity (v) is given as 1 m/s and the radius (r) is given as 0.5 m. Plugging these values into the formula, we get:
Angular velocity (ω) = 1 m/s / 0.5 m
= 2 rad/s
Therefore, the angular velocity of the object is 2 rad/s.
