Kinetic Friction v.s. Static Friction
Kinetic friction occurs when two objects are moving relative to each other and rub together. The coefficient of kinetic friction is typically denoted as μk, and is usually less than the coefficient of static friction for the same materials.
Static friction is friction between two solid objects that are not moving relative to each other. Kinetic friction is when two objects are rubbing against each other. Putting a book flat on a desk and moving it around is an example of kinetic friction.

Why is a drawing a sketch an important part of the scientific method and why do you always neglect this step!?!?

What happened when Jaguar Paw go back to the forest
When Jaguar Paw go into forest, he found that their village were already damaged. So Jaguar Paw and his family tried to built the house they can live. But, they found out they didn't have enough labor power to built the house. So they tried to find to place to live at night. Finally, they found the cave right next their village. The cave is really save but wet. So they lived in that few days and keep going their itinerary.
The forest is really dangerous, you will never know what will be happen. Jaguar Paw and his family walked very carefully in the forest. Suddenly, Jaguar Paw felt the threaten with something they don't know. He told them to stop and he hold his spear very hardly. At this moment, time was froze. The only sound can heard were the cry of insects.
Suddenly, the black shadow rushing out from the brushwood. Jaguar Paw used whole the power to punch the thing with his spear. The thing full over to the left. He moved closer to see, that's a panther. And Jaguar Paw moved back a little because there is other panther appear in the brushwood. A man versus two panthers. Jaguar Paw knew that is impassible for wining the fight. When he felt despair and fear. The were tow sharp arrows fly out from the brushwood, and pierce over panthers heads.
The panthers were dead. And a group people jumped out from the brushwood. Jaguar Paw very thanks them for saving he and his family. After the group of people saving them. The group people asked Jaguar Paw for going to their village with them.
That it, Jaguar Paw and his family get a little peace for a while ,until Spanish came and killed them.
