Instantaneous velocity is defined at _.
Correct answer: C. Instant time
- A. Particular displacement
- B. Instant acceleration
- C. Instant time
- D. Average time
Explanation
Correct Option: CInstantaneous velocity is defined at an instant of time. It represents the velocity of an object at a specific moment in time. It is the velocity at a particular point in time, not related to displacement, acceleration, or an average over a period.

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.
