Define average speed class 11
WebThe average speed is the distance (a scalar quantity) per time proportion. Speed is oblivious of bearing. Then again, Velocity is a vector quantity. It is h. Speed is the rate at which the position changes. The average velocity is displacement or position change i.e. a vector quantity per time proportion. Q.3. Write a short note on velocity. Web(iii) Average speed of a car between points A and B is 20 m/s, between B and C is 15 m/s and between C and D is 10 m/s. What is the average speed between A and D, if the time taken in the mentioned sections is 20s, 10s and 5s, respectively? (a) 17.14 m/s (b) 15 m/s (c) 10 m/s (d) 45 m/s. Show Answer

WebApr 6, 2024 · Speed is defined as the rate of change of distance, whereas velocity refers to the rate of change of displacement. The average speed of a moving body can never be zero or negative. But, the velocity of a moving body can undoubtedly be zero. Speed is distance/ unit time. On the other side, velocity is displacement/ unit time. WebSolution. The ratio of the total distance travelled in a specified direction to the total time taken by the body to travel the distance is called average velocity. Example: If you walk to a campsite 1 km away and then back to your starting point within 1 hour, then your average velocity will be zero because your initial and final position is ...
