FAQs on Introduction - Motion and Measurement of Distances - CBSE Class 6 Science Video Lecture

1. What is motion?
Ans. Motion is the change in position of an object with respect to its surroundings. It can be described in terms of distance, displacement, speed, velocity, and acceleration.
2. How is distance different from displacement?
Ans. Distance is the total path covered by an object in motion, irrespective of the direction. Displacement, on the other hand, is the shortest distance between the initial and final positions of the object, taking into account the direction of motion.
3. What are the different units used to measure distance?
Ans. Distance can be measured using various units such as meters (m), kilometers (km), centimeters (cm), or any other appropriate unit depending on the scale of measurement.
4. How is speed calculated?
Ans. Speed is calculated by dividing the distance traveled by an object by the time taken. The formula for speed is: Speed = Distance/Time.
5. What is the difference between speed and velocity?
Ans. Speed is a scalar quantity that only considers the magnitude of motion, whereas velocity is a vector quantity that considers both magnitude and direction. Therefore, velocity includes information about the direction of motion, while speed does not.
