1. What is Acceleration?

Acceleration is the rate of change of velocity of an object with respect to time. It is a vector quantity that describes how quickly an object changes its speed and/or direction of motion.

2. How Does the Calculator Work?

The calculator uses the acceleration formula:

Where:

• \( a \) — Acceleration (m/s²)
• \( V \) — Final velocity (m/s)
• \( V_0 \) — Initial velocity (m/s)
• \( t \) — Time interval (s)

Explanation: This formula calculates the average acceleration over a given time period by finding the change in velocity divided by the time taken.

3. Importance of Acceleration Calculation

Details: Calculating acceleration is fundamental in physics and engineering for analyzing motion, designing vehicles and machinery, and understanding forces acting on objects.

4. Using the Calculator

Tips: Enter final velocity and initial velocity in meters per second (m/s), and time in seconds (s). Time must be greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is negative acceleration?
A: Negative acceleration, often called deceleration, occurs when an object is slowing down. The velocity change is negative relative to the initial direction of motion.

Q2: How is acceleration different from velocity?
A: Velocity describes how fast an object is moving and in what direction, while acceleration describes how quickly the velocity is changing.

Q3: What are the SI units for acceleration?
A: The SI unit for acceleration is meters per second squared (m/s²).

Q4: Can acceleration be constant?
A: Yes, constant acceleration occurs when velocity changes at a constant rate over time, as in free-fall motion under gravity (ignoring air resistance).

Q5: How does acceleration relate to force?
A: According to Newton's second law, force equals mass times acceleration (F = m × a). Acceleration is directly proportional to the net force applied to an object.
