Acceleration Formula:
| From: | To: |
Acceleration is the rate of change of velocity with respect to time. It measures how quickly an object's speed is increasing or decreasing. Acceleration is a vector quantity, meaning it has both magnitude and direction.
The calculator uses the fundamental acceleration formula:
Where:
Explanation: This formula calculates the average acceleration over a given time interval by dividing the change in velocity by the change in time.
Details: Acceleration calculations are essential in physics, engineering, vehicle design, sports science, and many other fields. Understanding acceleration helps in analyzing motion, designing safety systems, and optimizing performance.
Tips: Enter change in velocity in meters per second (m/s) and change in time in seconds (s). Both values must be positive numbers greater than zero for accurate calculation.
Q1: What is the difference between acceleration and velocity?
A: Velocity is the rate of change of position, while acceleration is the rate of change of velocity. Acceleration tells you how quickly velocity is changing.
Q2: Can acceleration be negative?
A: Yes, negative acceleration (deceleration) occurs when an object is slowing down. The direction of acceleration is opposite to the direction of motion.
Q3: What are typical acceleration values?
A: Earth's gravity is approximately 9.8 m/s². Car acceleration ranges from 2-8 m/s², while high-performance vehicles can exceed 10 m/s².
Q4: How is instantaneous acceleration different?
A: Instantaneous acceleration is the acceleration at a specific moment, calculated as the derivative of velocity with respect to time.
Q5: What units are used for acceleration?
A: The SI unit is meters per second squared (m/s²). Other common units include feet per second squared (ft/s²) and gravitational units (g).
