How does an object's velocity affect it if it doesn't accelerate, spin, or change direction? Isn't it, after acceleration ends, once again in equilibrium; a state of omni-directional equality, i.e. stationary, until it collides with something else?

What is the formula for acceleration? I’ve heard it’s a=2d/t^2, where d is the displacement. However, after dropping a ball from 1 meter and measuring the time taken (0.32 sec), the acceleration I got is twice the actual value. What did I do wrong?
