## Free Fall Under Gravity

An object released from rest near Earth's surface accelerates uniformly downward.

### Formulas

**d = (1/2) * g * t²**

**v_f = g * t**

These assume no air resistance and zero initial velocity.

Exemplo Resolvido

A stone is dropped from a tall building and falls for 3 seconds.

  1. d = 0.5 * g * t²
  2. d = 0.5 * 9.81 * 9
  3. d = 44.145 m
  4. v_f = g * t = 9.81 * 3 = 29.43 m/s
