When you apply 80%+ of the relative maximum possible impulse to an object upon propelling it from your hands.

Notes:
-The maximum possible impulse is RELATIVE to what your maximum is (if you were to use the general maximum, any impulse would be ~0% of the maximum, as the maximum is now infinity). Your maximum is defined to be the largest impulse you can exert on the object.
-Any object propelled with less than 80% of the maximum possible impulse is considered to be thrown, and not yote
Person 1: "I throw this object over there!"
Person 2: "How hard will you throw it?"
Person 1: "Hard enough to apply an impulse of 500Ns!"
Person 2: "For your object the relative maximum possible impulse in air is 550Ns, so you will actually yeet it, not throw it"
Person 1: "You're mum gey stop correcting me"
