I am trying to get a box to float into the air, fly in a direction and then midair activate physics so that it flies off and falls to the ground without me having to animate that. I tried keyframing the "animate" toggle so that it turns off, but when I do this, the box jumps back to its starting position, instead of continuing from where the animation left off. How do I enable physics mid-animation?
At frame 0 put your object at its beginning location in the scene, press i > LocRotScale, enable the Animated option in the Physics panel and press i to keyframe it. At frame 10, move your object wherever you want, press i > LocRotScale, disable the Animated option in the Physics panel, press i to keyframe it.
