. Note the parabolic shape, where the peak represents the moment the object begins to fall back down.
In real-world scenarios (Parte 2 often introduces this), air resistance Fdcap F sub d acts against the motion. As speed increases, Fdcap F sub d increases until it equals the gravitational force Fgcap F sub g When , the acceleration becomes zero. Terminal Velocity ( 1_Caduta_libera_Parte_2_
): The constant maximum speed an object reaches during its fall. As speed increases, Fdcap F sub d increases
, it decelerates until it reaches its maximum height. At the peak of its trajectory, its instantaneous velocity is Set in the first equation: Maximum Height ( Hmaxcap H sub m a x end-sub ): Substitute tmaxt sub m a x end-sub into the position equation: 2. Visualize the Trajectory The graph below illustrates the position of an object thrown upward at At the peak of its trajectory, its instantaneous
Choose whether "up" or "down" is the positive direction (usually up is positive, making negative). Identify initial conditions: Determine
. In "Parte 2" of this study, we typically move beyond simple downward drops to analyze objects thrown vertically upward and the effects of air resistance.
