It is more convenient to measure the angular displacement in:
Correct answer: B. Radians
- A. Degrees
- B. Radians
- C. Grades
- D. Arcs
Explanation
Angular displacement is more conveniently measured in Radians, which is the SI unit for this purpose. Radians are preferred in physics calculations due to their relation to the circumference of a circle. Degrees, Grades, and Arcs are not commonly used in physics for angular displacement measurements, making them less suitable choices.

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.
