Acceleration Formula:
| From: | To: |
Acceleration is the rate of change of velocity with respect to time. It is a vector quantity that describes how quickly an object's velocity changes, including changes in speed and/or 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 fundamental in physics for understanding motion, designing vehicles, analyzing sports performance, and studying planetary movements. It's crucial in engineering, transportation safety, and space exploration.
Tips: Enter change in velocity in meters per second (m/s) and change in time in seconds (s). Both values must be positive, with time greater than zero.
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 slows down. The direction of acceleration depends on the coordinate system used.
Q3: What are typical acceleration values?
A: Earth's gravity: 9.8 m/s², Car acceleration: 2-3 m/s², Free fall: 9.8 m/s², Space shuttle launch: 29 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 is the relationship between force and acceleration?
A: According to Newton's second law, F = ma, where force equals mass times acceleration. Acceleration is directly proportional to the net force applied.
