1. What is Acceleration?

Acceleration is the rate of change of velocity of an object with respect to time. It's a vector quantity that describes how quickly an object speeds up, slows down, or changes direction.

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 (s)

Explanation: The formula calculates how much the velocity changes per unit time. Positive acceleration means speeding up, negative acceleration (deceleration) means slowing down.

3. Importance of Acceleration Calculation

Details: Calculating acceleration is crucial in physics, engineering, and automotive applications. It helps understand vehicle performance, safety systems, and motion dynamics.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between acceleration and velocity?
A: Velocity is the speed and direction of an object, while acceleration is how quickly that velocity is changing.

Q2: What is negative acceleration?
A: Negative acceleration (deceleration) occurs when an object is slowing down. The velocity decreases over time.

Q3: What units are used for acceleration?
A: The standard unit is meters per second squared (m/s²). Other units include km/h² or ft/s².

Q4: Can acceleration be zero?
A: Yes, when an object moves at constant velocity (no change in speed or direction), acceleration is zero.

Q5: How is acceleration related to force?
A: According to Newton's second law, force equals mass times acceleration (F = m × a).
