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 equation:

Where:

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

Explanation: The equation calculates how quickly an object's velocity changes over a given time period.

3. Importance of Acceleration Calculation

Details: Acceleration calculations are fundamental in physics and engineering, used in vehicle performance analysis, sports science, space travel, and understanding motion in everyday life.

4. Using the Calculator

Tips: Enter velocities in m/s and time in seconds. Time must be greater than zero. Positive acceleration indicates speeding up, negative indicates slowing down (deceleration).

5. Frequently Asked Questions (FAQ)

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

Q2: What does negative acceleration mean?
A: Negative acceleration (deceleration) means the object is slowing down in the positive direction or speeding up in the negative direction.

Q3: What is standard gravity (g) in m/s²?
A: Standard gravity is 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 fall?
A: Near Earth's surface, objects in free fall accelerate at about 9.8 m/s² (neglecting air resistance).
