The relation between arc "s" and " θ " (measured in radians) is _.
Correct answer: C. S =rθ
- A. 4S = rθ
- B. r= Sθ
- C. S =rθ
- D. S=r/θ
Explanation
Finding an arc length when the angle is given in degrees We know that if θ is measured in radians, then the length of an arc is given by s = rθ. Suppose θ is measured in degrees.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
