Welcome to projectile motion! This fundamental physics concept describes how objects move through the air under the influence of gravity. When we launch an object at an angle, it follows a curved parabolic path. The motion has both horizontal and vertical components, with gravity constantly pulling the object downward while it maintains constant horizontal velocity.
The initial velocity vector can be broken down into horizontal and vertical components. The horizontal component, v zero x, equals v zero cosine theta and remains constant throughout the flight. The vertical component, v zero y, equals v zero sine theta and changes due to gravity's downward acceleration. This decomposition is crucial for analyzing projectile motion.
Projectile motion has three distinct phases. The launch phase begins with maximum vertical velocity as the projectile accelerates upward. At the peak phase, vertical velocity becomes zero and the projectile reaches maximum height. Finally, in the landing phase, the projectile accelerates downward under gravity until it returns to ground level. Let's watch the motion unfold.
