Frequently Asked Questions
Common questions about the free online acceleration calculator.
Subtract the initial velocity from the final velocity and divide by the time taken. The
answer is in metres per second squared.
Acceleration equals the change in velocity divided by time, written as a = (v - u) / t, where
u is initial and v is final velocity.
The acceleration is 4 metres per second squared, because 20 metres per second divided by 5
seconds equals 4.
Negative acceleration, often called deceleration, means the object is slowing down because
its velocity is decreasing over time.
Switch the solve mode to force and mass and the calculator divides force in newtons by mass
in kilograms to give acceleration.
Average velocity is the mean of the initial and final velocities when acceleration is
constant, written as (u + v) / 2.
With constant acceleration the distance is initial velocity times time plus half the
acceleration times the square of the time.
Near the Earth surface the acceleration due to gravity is about 9.81 metres per second
squared, often rounded to 9.8 or 10.
