  • Soil Structure | Soils

    Aggregates on the soil surface can be broken down by the beating action of raindrops. The single particles that were once part of the aggregate can easily form a crust when the soil dries. The crust looks very similar to the crust formed on a puddle after it rains. It is very difficult for water to infiltrate a crust and for seedlings to push up through a crust. Thus, field operations that ...

  • Appliions of ImpulseMomentum Change Theorem

    The force in hitting is dependent upon how hard the hitter swings the bat or racket, not the time of impact. Instead, the followthrough increases the time of collision and subsequently contributes to an increase in the velocity change of the ball. By following through, a hitter can hit the ball in such a way that it leaves the bat or racket with more velocity (, the ball is moving faster ...
