If you drop an object, it will accelerate downward at 9.8 per second per second. If you instead throw it downwards, what will be its acceleration (in absense of air resistance)?
Answer: ___ m/s^2

Exactly the same as before: 9.8 m/s/s.
The only difference with letting the object go on its own is the initial speed. When you let the object go, the initial speed is 0 m/s; when you throw it downwards, it already has an initial speed of (for example) 3 m/s.

The acceleration of Earth's gravity on an object is always 9.812m/s^2
The fact that you are throwing it only changes the initial velosity from 0 to some other number at the point in which it is released.

Acceleration is change in velocity per unit time.
Whatever the initial velocity ( throw up or throw down) the change in velocity per unit time is a constant.
When we say that acceleraion is CONSTANT, it means it will not change with any thing.
The answer is 9.8m/ s^2.

9.8 Velocity is irrelevant to acceleration
