1. What is an Average Velocity Calculator in Calculus?

Definition: This calculator computes the average velocity over a time interval by integrating the velocity function and dividing by the time interval.

Purpose: It helps physics students and professionals determine the mean velocity of an object when given its velocity function over time.

2. How Does the Calculator Work?

The calculator uses the calculus formula:

\[ AV = \frac{\int_{t_1}^{t_2} v \, dt}{t_2 - t_1} \]

Where:

\( AV \) — Average velocity (m/s)
\( v \) — Velocity function (m/s)
\( t_1 \) — Initial time (s)
\( t_2 \) — Final time (s)

Explanation: The integral of velocity over time gives displacement, which when divided by the time interval yields average velocity.

3. Importance of Average Velocity Calculation

Details: Calculating average velocity is fundamental in kinematics, helping analyze motion when acceleration isn't constant.

4. Using the Calculator

Tips: Enter the velocity function (e.g., "3t^2 + 2t"), initial time, and final time (t₂ > t₁). The calculator will integrate the function over the interval.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between average and instantaneous velocity?
A: Average velocity is over an interval, while instantaneous velocity is at a specific moment (the derivative of position).

Q2: Can I use this for non-constant acceleration?
A: Yes, this method works for any velocity function, regardless of acceleration.

Q3: What if my velocity function has multiple variables?
A: This calculator handles single-variable functions of time (t) only.

Q4: How precise are the results?
A: Precision depends on the integration method used (not implemented in this demo).

Q5: What units should I use?
A: Use consistent units - typically meters for distance and seconds for time.
