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 changing. Positive acceleration indicates increasing speed, while negative acceleration (deceleration) indicates decreasing speed.
The calculator uses the 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, engineering, and everyday applications. They help in understanding motion dynamics, vehicle performance, sports science, and safety analysis in transportation systems.
Tips: Enter the change in velocity in meters per second (m/s) and the time interval in seconds (s). Both values must be positive, with time being 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 describes how velocity changes over time.
Q2: What are typical acceleration values?
A: Earth's gravity is 9.8 m/s². Car acceleration ranges from 2-8 m/s². High-performance sports cars can reach 10+ m/s².
Q3: Can acceleration be negative?
A: Yes, negative acceleration (deceleration) occurs when an object slows down. The calculator shows magnitude; direction depends on context.
Q4: What is instantaneous vs average acceleration?
A: This calculator gives average acceleration over a time interval. Instantaneous acceleration is the acceleration at a specific moment.
Q5: How does acceleration relate to force?
A: According to Newton's second law, F = ma, where force equals mass times acceleration. Acceleration is directly proportional to the net force applied.
