Understanding Circular Motion Formula: s=rθ

Click For Summary
SUMMARY

The discussion centers on the circular motion formula, specifically the relationship defined by s = rθ, where s represents the arc length, r is the radius, and θ is the angle in radians. Participants clarify that the formula accurately describes the arc length subtended by an angle in a circle. The formula is essential for understanding circular motion in physics and mathematics, emphasizing the importance of using radians for angle measurement.

How is the formula θ= s/r
 
Physics news on Phys.org
Welcome to PF;
When you ask a question you should explain your reasoning.
[itex]s=r\theta[/itex] ... is the formula for the arc-length subtended by an angle ... if the angle is in radiens. How can it not be that?
