The ratio of change in the path to the time taken to traverse through it is known as average velocity. The correct formula to describe the average velocity is [tex]v_{av}=\dfrac{x_{f}-x_{i}}{t_{f}-t_{i}}[/tex]. Hence, an option first is correct.
What is Average Velocity?
When an object covers some displacement, then the ratio of change in position of the object to the time interval is known as average velocity.
- The second option incorrectly defines the average velocity as the ratio of change in the time interval and change in the position. Hence, it is not correct.
- The third option defines the ratio of distance and time, which is simply known as speed. So, the average velocity condition is not satisfied and hence it is an incorrect option.
- Similarly, the fourth option also gives an incorrect formula for the average velocity (given as the ratio of time and distance). Hence, it is an incorrect option.
- However, the first option correctly describes average velocity as the ratio of change in position to the time interval. Hence, an option first is correct.
Thus, we can conclude that the correct formula to describe the average velocity is [tex]v_{av}=\dfrac{x_{f}-x_{i}}{t_{f}-t_{i}}[/tex]. Hence, an option first is correct.
