MCQ
Which of the following can be used to describe how fast an object is moving along with the direction of motion at a given instant of time?
- ✓Instantaneous velocity
- BInstantaneous speed
- CAverage velocity
- DAverage speed
✓
Answer
Correct option: A.
Instantaneous velocity
Instantaneous velocity describes the velocity of an object at a given time instant.
Average speed is the speed at which the object travels throughout the time period and not an instant.
Speed is a scalar quantity; hence it cannot show the direction of motion.
