Laws of physics? Like the law of motion in Indiana Jones & the Temple of Doom where they fall of a cliff and land hundreds of feet down on snow and aren't even bruised? Heck, they were in a liferaft that they had just used to jump out of an airplane!
We also had a part in Raiders of the Lost Ark where Jones and Marion push a huge ancient brick out of a wall to escape the Well of Souls. It's bad enough that the wall just happened to be sitting there in broad daylight and no one ever though to look in there for centuries, but if you watch carefully you'll see that this huge brick that supported an enormous structure BOUNCES AWAY! I'm not kidding. Watch the shadow of the brick when they push it.
There's also the basic rule that you have to reload your pistol every so often. In the bar fight Indiana Jones fires around 50 rounds and reloads once.
Then there's Indiana Jones & the Last Crusade. These guys are running on the top of a moving train and they aren't blown away by the wind resistance? I have to wonder how young Indy was able to escape from the magic box and get off of a moving train without the law of motion requiring him to bounce painfully at at least 60 mph on desert terrain. Nope, he runs out on his feet!
