Deduction! Rocks!

[math]

W = \Delta Ec

[/math]

[math]

F. \Delta x = \frac{mV^{2}_{f}}{2} - \frac{mV^{2}_{o}}{2}

[/math]

[math]

m.a. \Delta x = \frac{mV^{2}_{f}}{2} - \frac{mV^{2}_{o}}{2}

[/math]

divide by (m) on both sides

[math]

a. \Delta x = \frac{V^{2}_{f}}{2} - \frac{V^{2}_{o}}{2}

[/math]

[math]

{V^{2}_{o}} + 2.a. \Delta x = {V^{2}_{f}}

[/math]

[math]

{V^{2}_{f}} = {V^{2}_{o}} + 2.a. \Delta x

[/math]

Just to show that everything we learn in physics at school is actualy 1 thing

Dynamics, Cinematics and etc

Isn't is beutiful!

(forgive my english)
