Ok, what?

Animation isn’t always “realistic”. That’s why animated things are made a lot of the time.

I think you might be confused, when I said the second kick, I meant the kick that came after the first. That kick was brief, and he only stayed in a kicking position for a tiny frame or two.

What I said would be realistic because he’s sending upwards force into that kick. Think about it in the reverse. Imagine dropping a weight, and then catching right before it hits the ground and trying to lift it up. The weight, since its developing quite a bit of momentum, is essentially gaining temporary weight added on by gravity, so when you catch it, you’re pulled down a little, regardless of how well you can lift that weight normally. When you start pulling it up, that energy from the fall dissipates, and it slowly goes back to it’s original weight, and you can lift it faster. You could probably demonstrate this to yourself with a gallon of milk. In the situation of the kick it applies but in reverse. If we’re relating everything from the weight demonstration to the kick, the weight is the stickmans leg, gravity is the force behind the kick, and you, trying to pull the weight up, is gravity. Even if you try and replicate the stickmans moves at home, you’ll notice when falling down, you speed up the longer you’ve been falling.
