**A free fall of a material point** is being examined. In order to find the solution of the considered example formulas for an accelerated motion and kinetic and potential energy in the gravitational field are used.

v = v_0 + a \cdot t

s = v_0 \cdot t + \frac{a \cdot t^2}{2}

E_k = \frac{m \cdot v^2}{2}

E_p = m \cdot g \cdot h
