Acceleration Formula
The average acceleration formula links velocity and time:
a = (vf - vi) / t
Where:
a = acceleration (m/s²)
vf = final velocity
vi = initial velocity
t = time taken
Real World Examples
- Gravity: Objects in free fall accelerate downwards at approximately 9.8 m/s².
- Cars: A high-performance car accelerates from 0 to 60 mph in about 3-5 seconds.
FAQ
What is acceleration?
Acceleration is the rate at which an object changes its velocity. It is a vector quantity.
What does negative acceleration mean?
Negative acceleration (often called deceleration or retardation) means the object is slowing down in the positive direction, or speeding up in the negative direction.
What is the standard unit for acceleration?
The SI unit for acceleration is meters per second squared (m/s²). It tells you by how many meters per second the velocity changes every second.
