Acceleration is not calculated as a = d/t^2. The correct formula for acceleration is given by:
a = (v - u) / t
Where: a = acceleration v = final velocity u = initial velocity t = time
This formula calculates acceleration as the change in velocity per unit time. It is derived from the kinematic equation:
v = u + at
By rearranging the equation, we can solve for acceleration:
v - u = at a = (v - u) / t
In this formula, acceleration is defined as the rate of change of velocity over time. It measures how quickly the velocity of an object is changing. The formula you mentioned, a = d/t^2, is not a correct representation of acceleration.
