Question
The relationship between the arc length (s) described by an object in circular motion, the radius of the circle (R), and the angular displacement (θ) is given by which formula?
Correct Answer
Option D is the correct answer.
Detailed Explanation
The lecture states that s is the length of arc described by the angle θ and R is the radius, establishing the fundamental geometric relationship s = Rθ (with θ in radians).
Hint
This relationship is analogous to the formula for the circumference of a circle, C = 2πR, which is a special case where θ = 2π radians.
