Why does the height model of a thrown object apply to a dropped object as well?

Hint: What is the initial vertical velocity of a dropped object?Why does the height model of a thrown object apply to a dropped object as well?
The answer is, there is an instant when a thrown object (upwards) reaches a velocity of zero, which is what the dropped object has the instant it is released. From these two instants in time, the response of each object is only to gravity.Why does the height model of a thrown object apply to a dropped object as well?
It applies to both because acceleration is always in the same direction-down. If you throw the object up, it's velocity will be opposite to its acceleration.


If you define ';down'; as negative, then ';up'; will be positive, so as the object goes up, the acceleration will subtract from its speed, instead of adding.
Simple: Gravitational force affects both equally.
