1. What Is The Final Velocity Formula?

The formula v = 2s/t - u calculates the final velocity of an object when you know the distance traveled, time taken, and initial velocity. This equation is derived from the relationship between distance, average velocity, and time.

2. How Does The Calculator Work?

The calculator uses the formula:

Where:

• \( v \) — Final velocity (m/s)
• \( s \) — Distance traveled (m)
• \( t \) — Time taken (s)
• \( u \) — Initial velocity (m/s)

Explanation: This formula calculates the final velocity by first determining the average speed (s/t), then using the relationship between initial velocity, final velocity, and average velocity.

3. Applications Of Final Velocity Calculation

Details: This calculation is useful in physics problems involving constant acceleration, motion analysis, and engineering applications where velocity changes need to be determined from distance and time measurements.

4. Using The Calculator

Tips: Enter distance in meters, time in seconds, and initial velocity in m/s. All values must be valid (time > 0).

5. Frequently Asked Questions (FAQ)

Q1: When is this formula applicable?
A: This formula works for motion with constant acceleration, where the average velocity equals (u + v)/2.

Q2: What if acceleration is not constant?
A: This formula would not be accurate for non-constant acceleration scenarios. More complex equations would be needed.

Q3: Can this formula give negative results?
A: Yes, a negative result indicates the final velocity is in the opposite direction to the initial velocity.

Q4: How precise should my measurements be?
A: For accurate results, measure distance and time as precisely as possible, especially for short time intervals.

Q5: What are typical units for these measurements?
A: Standard SI units are meters for distance, seconds for time, and meters per second for velocity.
