1. Initial Velocity: When an object is first launched upward, it has its initial velocity. This is the velocity at the moment it starts moving upward.
2. Decreasing Velocity: As the object travels upward, gravity acts on it, pulling it downwards. This force causes the upward velocity to decrease gradually. The object slows down as it rises.
3. Zero Velocity at the Peak: At the highest point of its trajectory, the object momentarily comes to a stop. Its velocity becomes zero.
4. Increasing Downward Velocity: After reaching the peak, the object starts to fall back down. Gravity now accelerates it downwards, causing its velocity to increase in the downward direction.
In summary: The velocity of an object moving upward decreases until it reaches zero at the peak, and then increases in the downward direction as it falls back down.
Important Note: This assumes no air resistance. In reality, air resistance would also play a role, further slowing down the object.
