1. What is Acceleration?

Acceleration is the rate of change of velocity of an object with respect to time. It's a vector quantity (has both magnitude and direction) measured in meters per second squared (m/s²).

2. How Does the Calculator Work?

The calculator uses the acceleration formula:

Where:

• \( a \) — Acceleration (m/s²)
• \( v_f \) — Final velocity (m/s)
• \( v_i \) — Initial velocity (m/s)
• \( t \) — Time interval (s)

Explanation: The formula calculates how quickly an object's velocity changes over a specific time period. Positive acceleration means speeding up, negative acceleration (deceleration) means slowing down.

3. Importance of Acceleration Calculation

Details: Acceleration is fundamental in physics for analyzing motion, designing vehicles, understanding forces, and solving real-world problems like vehicle braking distances or rocket launches.

4. Using the Calculator

Tips: Enter velocities in m/s and time in seconds. Time must be greater than zero. The calculator will compute the average acceleration over the given time interval.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between acceleration and velocity?
A: Velocity is speed with direction, while acceleration is how velocity changes over time.

Q2: Can acceleration be negative?
A: Yes, negative acceleration (deceleration) means the object is slowing down.

Q3: What is standard gravity (g) in m/s²?
A: Approximately 9.80665 m/s², the acceleration due to Earth's gravity at sea level.

Q4: How is acceleration related to force?
A: According to Newton's Second Law: F = ma (Force equals mass times acceleration).

Q5: What's the acceleration of free-falling objects?
A: On Earth, about 9.8 m/s² downward (neglecting air resistance).
