Scenario: Imagine you throw a ball straight up into the air.
* Velocity: The ball initially travels upwards with a positive velocity.
* Acceleration: Gravity acts on the ball, constantly pulling it downwards. This means the acceleration due to gravity is negative, acting in the opposite direction to the ball's velocity.
Result: As the ball travels upwards, its velocity decreases due to the opposing acceleration. Eventually, the velocity reaches zero at the peak of its trajectory. Then, as the ball falls back down, its velocity is now negative (downwards) but the acceleration remains constant, still pointing downwards.
This example demonstrates how acceleration can be in the opposite direction of velocity, causing the object to slow down or change its direction.
