FAQs on Distance, Displacement, Average Speed, Average Velocity Video Lecture - Physics for EmSAT Achieve

1. What is the difference between distance and displacement?
Ans. Distance is the total length covered by an object regardless of its direction, while displacement is the shortest distance between the initial and final positions of an object in a specific direction.
2. How is average speed calculated?
Ans. Average speed is calculated by dividing the total distance traveled by the total time taken to travel that distance.
3. What is the significance of average velocity in physics?
Ans. Average velocity not only considers the total displacement but also the direction of motion, providing a more accurate representation of an object's motion compared to average speed.
4. Can an object have a non-zero average velocity but zero average speed?
Ans. Yes, an object can have a non-zero average velocity if it changes direction during its motion, while still having zero average speed if the total distance traveled is zero.
5. How do you calculate average velocity?
Ans. Average velocity is calculated by dividing the total displacement by the total time taken to cover that displacement. It includes both the magnitude and direction of the displacement.
