* Velocity: At the highest point, the ball's velocity is zero. This is because the ball momentarily stops moving upwards before it starts falling back down.
* Acceleration: The ball's acceleration is constant throughout its flight and is equal to the acceleration due to gravity (approximately 9.8 m/s² downwards). Even though the ball has zero velocity at the highest point, gravity is still acting on it, pulling it back down.
Key Concept:
The difference between velocity and acceleration is crucial:
* Velocity tells us how fast something is moving and in what direction.
* Acceleration tells us how the velocity is changing over time.
In Summary:
When a ball is thrown upwards, it slows down as it travels against gravity. At the highest point, it momentarily stops moving upwards, resulting in zero velocity. However, gravity continues to act on the ball, causing it to accelerate downwards, ready to begin its descent.
