A ball thrown upwards
* Initial State: You throw a ball straight upwards. At the moment it leaves your hand, it has an initial upward velocity.
* Gravity's Influence: As the ball travels upwards, gravity constantly pulls it downwards. This slows the ball down until it momentarily stops at its highest point.
* Speeding Up: Once the ball starts falling back down, gravity continues to act on it. This time, gravity's pull is in the same direction as the ball's motion, causing it to *speed up* as it falls back to Earth.
Key Concepts:
* Acceleration: Gravity causes an acceleration of 9.8 m/s² (approximately) towards the center of the Earth. This means that the ball's velocity increases by 9.8 meters per second every second it falls.
* Direction: The direction of the force of gravity is always downwards. This means that it can either slow an object down (if the object is moving upwards) or speed it up (if the object is moving downwards).
