* Initial State: You're at rest, meaning your velocity is zero.
* Change in Velocity: The moment you jump off the board, gravity begins to act on you, pulling you downwards. This pull causes your velocity to increase, meaning you start falling faster and faster.
* Result: As you fall, your velocity continues to increase until you hit the water.
This is a simple example of how gravity causes a change in velocity. Gravity is a constant force that acts on all objects with mass, always pulling them towards the center of the Earth. This force results in a continuous acceleration, meaning your velocity keeps changing as long as gravity is acting on you.
