* Gravity's Constant Pull: The moment an object is released, Earth's gravity starts acting on it. This force pulls the object downwards, causing it to accelerate.
* Acceleration is the Rate of Change of Velocity: Acceleration means a change in velocity over time. Since gravity constantly pulls the object downwards, its velocity constantly increases.
* Initial Velocity: When an object is dropped, its initial velocity is zero. This means it's at rest before gravity takes over.
In summary:
* Gravity acts on the object *immediately* after it's dropped.
* Gravity causes the object to *accelerate* downwards.
* Acceleration means the velocity of the object *continuously increases* over time.
It's important to distinguish between the *instant* gravity acts and the *instant* the object reaches a measurable velocity. The change in velocity happens in a very short time, but it's not instantaneous.
