Jumping Mountain Goat

Jumping Mountain Goat

What happens when you find a seemingly old and foreign video showing goats doing crazy things? Try to figure if it is possible. The poor resolution of this video does not help – but I will do what I can. Since the goats are essentially in projectile motion during the jumps, I can look a the horizontal velocity and the vertical acceleration. This is what I get.

Notice that these plots are for multiple jumps. But during each one, the horizontal velocity seems constant and the vertical acceleration seems constant as well. Ok, so that doesn’t show it’s fake. But is it even physically possible? Yes. Possible, but still difficult to tell. I really had to guess about the both the frame rate and scale of the video.

The Verdict: If I had to pick, I would say real. However, this one could go either way. It really depends on the scale. Here is the original post with the details.

-	'''Crouch Jumping''' is a technique in which a player crouches directly after jumping. The move brings the player's legs up, reducing their height and allowing them to jump into higher places or smaller gaps. In ''[[Halo: Combat Evolved]]'', it could also lower fall damage.	+	'''Crouch Jumping''' is a technique in which a player crouches then jumps.

-	The technique is extremely simple to perform. Jump, and crouch in midair. This should enable you to get to previously-unreachable places.	+	The technique is extremely simple to perform. crouch, then jump in midair. This should enable you to get to previously-unreachable places.
	As previously mentioned, Crouch Jumping is useful for jumping to slightly higher locations or allows you to jump off higher places and take less damage. It is also an effective technique to use when strafing around an enemy during a firefight. It can be used to help teammates (in [[Cooperative Play|Co-op]] or team [[Multiplayer]] games) reach higher places.
