Concrete does not rust, rot, or burn, saving energy and resources needed to replace or repair damaged buildings and infrastructure. • Because of its rigidity, concrete pavement can enhance the fuel efficiency of vehicles that travel on roads when compared to other pavements. If concrete pavements were used by the U.S. road system, fuel
Imagine that two balls are hit with the same speed from the baseline to land at the same location at the opposite service line. If one is launched at 30 degrees and the other at 60 degrees, then the 60-degree ball will follow a steeper, higher trajectory and thus gain more vertical speed on the way down.
So when you have a surface like leather against concrete, it's gonna be grippy enough, grippy enough that as this ball moves forward, it rolls, and that rolling motion just keeps up so that the surfaces never skid across each other. In other words, this ball's gonna be moving forward, but it's not gonna be slipping across the ground.
