Which law is it?

I am always amazed by how often I see newtons laws in action. Watch this video:
  • Which law is being shown here? (Actually, you can see all three, but there is one that is more obvious that the others)
  • See if you can identify at least 2 examples of each of newtons laws in this video!


Also, we can talk about torque here. 
  • A large flatbed truck like this can have a mass of 3,000 kg mass. If the center of mass of the truck is 4 m in front of the axle, and the rear of the truck is 2.5 meters behind the truck, how much weight could you have centered over the back edge before tipping the truck up?
  • When balanced like in #2, there are only 2 significant torques. What force provides the 3rd force to keep the system from rotating when the load is not that heavy?
  • Can you draw a torque diagram for this when the truck is tilting up from the weight of the load?
