Question:
If a moving body changes its position from \(x_1\) to \(x_2\) in a time interval \(\Delta t\), then \(\frac{x_2 - x_1}{\Delta t}\) is defined as
If a moving body changes its position from \(x_1\) to \(x_2\) in a time interval \(\Delta t\), then \(\frac{x_2 - x_1}{\Delta t}\) is defined as
Show Hint
Velocity is displacement/time, while speed is distance/time.

- average acceleration
- average velocity
- instantaneous acceleration
- instantaneous velocity
- average displacement
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
This is a basic definition in kinematics.
Step 2: Detailed Explanation:
Average velocity is defined as the total displacement (\(\Delta x = x_2 - x_1\)) divided by the total time taken (\(\Delta t\)). It is a vector quantity. Instantaneous velocity is the limit of this as \(\Delta t\) approaches 0. Average acceleration is the change in velocity divided by time.
Step 3: Final Answer:
\(\frac{x_2 - x_1}{\Delta t}\) is the average velocity.
