An object is in "Free-Fall" under all the given conditions. This is because free-fall refers to any motion of a body where gravity is the only force acting upon it.

1. When it is ONLY under the influence of gravity: This is the basic definition of free-fall. An object is in free-fall when the only force acting on it is gravity.

2. When it is going up: Even when an object is moving upwards, it is still under the influence of gravity. The force of gravity is acting to slow the object's upward motion until it stops at its peak, and then accelerates it back down towards the ground.

3. When it is thrown at the ground: When an object is thrown towards the ground, it is still only under the influence of gravity. The initial force applied to throw the object does not continue to act on it.

4. When it is thrown upward: Similar to when it is going up, an object thrown upward is still in free-fall after the initial throwing force has ceased to act on it. The object will rise, then stop, and then begin to fall back to the ground, all under the influence of gravity.

So, the answer is "All of these".
