1. Initial Upward Motion:
* When you throw the ball, you give it an initial upward velocity. This velocity causes the ball to move upwards, momentarily overcoming the force of gravity.
2. Slowing Down:
* As the ball travels upward, gravity constantly acts on it, pulling it downwards. This force gradually reduces the ball's upward velocity, causing it to slow down.
3. Peak Height:
* Eventually, the upward velocity is completely cancelled out by gravity. At this point, the ball momentarily stops moving upwards and reaches its highest point, known as the peak.
4. Downward Motion:
* Once the ball reaches its peak, gravity continues to act on it, now pulling it downwards. This causes the ball to accelerate downwards, increasing its velocity.
5. Impact:
* The ball continues falling until it hits the ground. The impact with the ground brings the ball to rest, momentarily, unless it bounces.
In Summary:
* Gravity is responsible for the ball's deceleration during the upward motion, bringing it to a stop at the peak.
* Gravity then accelerates the ball downward, causing it to fall back to the ground.
Important Notes:
* The trajectory of the ball is a parabola, due to the constant downward acceleration caused by gravity.
* The initial velocity and launch angle of the throw affect the ball's height, range, and overall trajectory.
* Air resistance also plays a minor role, opposing the ball's motion and slightly affecting its trajectory.
