# What hits Joker's thug in the bus scene?

It seems that one of Joker's thugs at the beginning of The Dark Knight lost his consciousness because he was hit by something. However, there is nothing heavy enough to have caused such an effect in that scene (he got hit by a wood panel which weighed 5 kilograms tops). Is this a mistake in the film?

• The wooden panel you're referring to seems to be part of the wall, likely weighs more, and is smashed against him by the bus. It seems quite reasonable the man is knocked unconscious. May 13, 2020 at 21:19
• I imagine it was meant to look like he got his by the bus, but IRL that would have killed the stunt man so, ya know, movie magic. May 13, 2020 at 21:55

## He got hit by the panel as you observed

BUT, it's not the weight of it that is important, it's the amount of kinetic energy that it carries.

A baseball doesn't weigh very much but at 90mph it will take you out if it hits you in the head.

A more extreme example is a bullet, weighs a couple of ounces but when fired from a gun it's lethal.

In this case, the panel (and I suspect it weighed considerably more than 5 kilos) has the force of a bus behind it and accelerates from zero to quite a speed before it hits the thug.
