Question
What is the difference between average and instantaneous velocity?
Solution
| Average velocity | Instantaneous velocity |
|
1. The velocity with which the body covers the same distance in the same time as the body actually covered with variable velocity is known as average velocity. It is measured as the ratio of total displacement to total time taken. |
1. Instantaneous velocity of a body is defined as the velocity of the body at a particular instant and it is the limiting case of average velocity as the time interval approaches zero. That is instantaneous velocity is, |
| 2. Average velocity between two times is equal to the slope of the line joining the two points on the position vs. time graph. | 2. Instantaneous velocity of an object at a particular time is equal to the slope of it's position vs. time graph at that time. |
