How does the car overcome the ground friction

1. The friction resistance of the wheel is actually the friction torque. In high school physics, the problem of finding the friction resistance of wheels is not strict. It's just seen as resistance. It's not friction, because static friction doesn't work (the point of action of the force doesn't move). Energy is just resistance. The method is that the work done by the combined external force is equal to the change of kinetic energy. The total work minus the work done by other forces, that is, the work done by the rubbing force. So f = w / s
the theoretical mechanics of college physics can be solved

2. Need extreme overclocking. Don't use that memory. The motherboard of the player's country can support very high frequency memory

this is more expensive than many

power supply of the previous series of brand power supply, 900w-1000w can meet your extreme overclocking
with such a good configuration, which 1TB hard disk? How many games can you hold, At least, the minimum is more than 2TB.
