Acceleration Formula:
| From: | To: |
Acceleration is the rate of change of velocity with respect to time. It measures how quickly an object's speed or direction changes. In physics, acceleration is a vector quantity that describes both magnitude and direction of velocity change.
The calculator uses the acceleration formula:
Where:
Explanation: This formula calculates average acceleration by dividing the change in velocity by the time interval over which the change occurred.
Details: Acceleration calculations are fundamental in physics, engineering, and everyday applications. They help understand motion dynamics, design transportation systems, analyze sports performance, and ensure vehicle safety.
Tips: Enter change in velocity in meters per second (m/s) and change in time in seconds (s). Time must be greater than zero. The result will be acceleration in meters per second squared (m/s²).
Q1: What is the difference between acceleration and velocity?
A: Velocity describes how fast an object is moving and in what direction, while acceleration describes 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 direction of velocity change.
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: This calculator finds average acceleration. Instantaneous acceleration is the acceleration at a specific moment, calculated using derivatives.
Q5: What units are used for acceleration?
A: The SI unit is meters per second squared (m/s²). Other units include feet per second squared (ft/s²) and gravitational units (g).
