* Gravity's Pull: Earth exerts a constant downward force on all objects, including the stone. This force is called gravity.
* Opposing Motion: When you throw the stone upwards, its initial velocity is directed against the force of gravity. This means gravity works to slow the stone down.
* Deceleration: As gravity acts on the stone, it causes a negative acceleration (deceleration), reducing the stone's upward velocity.
* Zero Velocity: Eventually, the stone's upward velocity reaches zero. At this point, it has momentarily stopped moving upwards.
* Fall Back Down: After reaching zero velocity, gravity continues to pull the stone downwards, causing it to accelerate back towards the Earth.
In simpler terms: Imagine you're throwing a ball straight up in the air. The moment it leaves your hand, gravity starts pulling it back down. This pull slows the ball down until it momentarily stops at its highest point, and then it falls back down.
