The time period is defined as the time required to traverse _ by a revolving body:
Correct answer: C. One revolution
- A. One radian
- B. 180 degrees
- C. One revolution
- D. 90 degrees
Explanation
The time period is the time taken for a revolving body to complete one full revolution around the circle. In this case, the correct answer is 'One revolution' because the time period is defined based on a complete cycle. The other options are incorrect because they refer to angles (radian, degrees) that do not directly relate to the time taken for a complete revolution.

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.
