* Projectile motion is the motion of an object launched into the air, moving under the influence of gravity only.

* The ball is thrown upwards, giving it an initial upward velocity.

* As the ball travels upwards, gravity acts on it, slowing it down until it momentarily stops at its highest point.

* Then, gravity pulls the ball back down, accelerating it towards the ground.

Key characteristics of projectile motion:

* Parabolic Path: The path of the ball is a parabola (neglecting air resistance).

* Constant Horizontal Velocity: The horizontal velocity of the ball remains constant throughout its flight.

* Vertical Acceleration: The ball experiences a constant downward acceleration due to gravity.
