The video tutorial explains the derivation of kinematic equations for uniformly accelerated motion. It begins with setting initial conditions and assumptions, followed by analyzing velocity-time graphs. The first kinematic equation, v = u + at, is derived using the definition of acceleration. The second equation, x = ut + 1/2at², is derived using the area under the velocity-time graph. Finally, the third equation, v² = u² + 2ax, is derived by substituting time in the second equation.
