Rate of Acceleration Calculator
Calculate acceleration using velocity and time with our easy-to-use tool
The Acceleration Formula
Acceleration is calculated using the following formula:
a = (vf – vi) / t
Where:
- a = acceleration (m/s²)
- vf = final velocity (m/s)
- vi = initial velocity (m/s)
- t = time (seconds)
Frequently Asked Questions
What is acceleration?
Acceleration is the rate at which an object’s velocity changes over time. It’s a vector quantity, meaning it has both magnitude and direction.
How is acceleration different from velocity?
Velocity describes how fast an object is moving and in what direction, while acceleration describes how the velocity is changing.
Can acceleration be negative?
Yes, negative acceleration (often called deceleration) means the object is slowing down in the direction of motion or accelerating in the opposite direction.
What units are used for acceleration?
The standard unit for acceleration is meters per second squared (m/s²). Other units include feet per second squared (ft/s²) or kilometers per hour squared (km/h²).
