Definition and Characteristics of Parabolic Motion
📌 Parabolic motion (Gerak Parabola) describes the movement of an object thrown upwards, resulting in a curved path resembling a parabola.
📐 This motion involves two axes: the horizontal axis (X) and the vertical axis (Y).
🏀 An example given is shooting a three-point basketball shot, where the trajectory forms a curve.

Mathematical Calculation Example
🔢 For a basketball thrown at an elevation angle of $30^{\circ}$ with an initial velocity ($v_0$) of $30 \text{ m/s}$:
➡️ The initial velocity component on the X-axis ($v_{0x}$) is calculated as $v_{0} \cdot \cos(\text{angle})$.
➡️ Substituting values: $v_{0x} = 30 \cdot \cos(30^{\circ}) = 30 \cdot \frac{\sqrt{3}}{2} = 15\sqrt{3} \text{ m/s}$.
⬆️ The horizontal velocity remains constant, meaning the velocity at the highest point is still $15\sqrt{3} \text{ m/s}$.

Real-World Applications of Parabolic Motion
🚀 Parabolic motion principles are observed in everyday activities beyond sports, including rocket launches in technology.
🌱 When watering plants, the trajectory of the water forms a parabola to cover a wider area.
🎯 In archery, the arrow released by the archer follows a parabolic path before hitting the target.
⛲ Water flowing from a fountain also demonstrates parabolic motion as the stream moves from one point to another before returning to the pool.

Key Points & Insights
➡️ Parabolic motion is a common physics phenomenon with numerous practical applications across sports, technology, and daily life.
➡️ Understanding the horizontal ($v_{0x}$) and vertical components is crucial for analyzing projectile trajectories.
➡️ The calculation $v_{0x} = v_0 \cos(\theta)$ determines the constant horizontal speed throughout the flight.
