Legendary mining tools
1. First of all, you need to prepare a pickaxe, which can be sold in beech's weapons store. It can be equipped at level 11
the mine is on the top right of the map of beech province. Press tab to see a small white sign on the top right. Run that way.
First of all, you should have mining tools. Gamers can buy mining tools through stores. When gamers reach a certain level, they can equip and start mining
through the activity interface, players can enter the mining method, as shown in the figure:
enter the mine cave, and then there are miners everywhere. Find a place with fewer people and start digging. When digging, sometimes there will be false digging phenomenon, that is, looking at digging, but there has been no mine. You just need to see if there is slag on the ground. If it is useful, you need to move it until there is slag falling
don't just dig in one place. After a period of time, it's hard to go out again. It will take a period of time to refresh, so players need to change places to dig more mines
According to the kinetic energy theorem, the work done by the external force to move an object from point a to point B on the inclined plane is: (the increment of the kinetic energy of the object + the work done by overcoming friction + the work done by overcoming gravity.) There are only three forces acting on an object: gravity, friction and surface support
the extra work is the work to overcome the friction, the work to lift the moving pulley, the work to overcome the gravity of the rope and the work to overcome the air resistance
therefore, the main reasons for doing extra work are to overcome the work done by the gravity of the moving pulley, the work done by overcoming the friction and the rope weight, and the work done by overcoming the air resistance (which can be ignored sometimes).
therefore, a
