* Constant Acceleration Due to Gravity: The primary force acting on the ball throughout its flight is gravity. Gravity exerts a constant downward acceleration of approximately 9.8 m/s². This means the ball's velocity decreases as it goes up and increases as it comes back down.
* Changing Direction: When the ball is thrown upwards, its initial velocity is positive (upwards). As gravity acts on it, the velocity decreases until it reaches zero at the peak of its trajectory. At that moment, the velocity changes direction, becoming negative (downwards) as the ball falls back down.
Therefore, the acceleration due to gravity is constant throughout the ball's motion, but the ball's overall acceleration changes because its velocity is changing both in magnitude and direction.
