4.10 Angular Momentum

356 Words2 Pages

4.3.8 When a ball is pitched, it stay in motion until it either fall, or is acted on by another object such as the bat, or caught by a person. The pitch and speed depends on the mass of the ball. Although it should be the same size, practicing with different balls will affect the speed. During the process of pitching, this will have a reaction on the ball causing it to move from one point to another. 4.3.9 ANGULAR MOMENTUM = MOMENT OF INERTIA X ANGULAR VELOCITY The angular velocity is the axis, the moment of inertia is the resistance to change, and the angular momentum is the product of the body’s moment of inertia. 4.3.10 -Angular momentum is conserved when there is no torque. This can determine the movement for angular acceleration about

    However, many don’t realize the skill it takes to truly succeed and how difficult bowling really is,” Schuckman said. “It’s not as easy as standing up there and throwing a ball at the pins.” According to Schuckman, each lane has its own feel that needs to be considered before releasing the ball down the alley. “You have to worry about oil patterns, if you’re hitting your mark, if you’re knees are bent and if your arm swing is accurate. And as the game goes on, things change — oil pattern breaks down and you have to constantly adjust to everything you’re doing.”

  • Evolution Of Baseball Prior To 1940

    This made for a lot of balls to be different weights and shapes which made them never quite the same as the next one in line which made for the ball to have different movements when being pitched and sometimes hit. Over the course of time the baseball has changed from a very loosely wound ball to very tight and compact ball which gives the ball more pop and flight. Baseball also changed the color of the baseball from a leather brown to the current white we have today which is due to the visibility and safety factor. Overall, the ball itself was probably the largest equipment factor prior to 1940 as many changes were brought in, such as the implementing of a cork center and the classic figure-8 style

    The Softball Pitcher is the Most Influential Position on the Team Coach said there is no “I” in team, yet sometimes it felt as if there should be one. As the only pitcher on my high school fast-pitch softball team, I was often exhausted by the end of a game, but I knew my only option was to keep pitching. Although the fielders behind me were trying hard, none were great athletes; we all knew that if I did not strike a batter out, my defense would often be unable to make an out in the field. In fast-pitch softball, the pitcher is the team’s most influential position by limiting batter effectiveness, staying physically and mentally tough, and being a key fielder.

    When the bowler in cricket throws the ball, he is able to bounce it off the ground, to make it harder for the batsman to hit the ball.

Cricket has a round field that a batter try’s to hit the ball to any place in field, while trying to avoid hit-ting the ball to a fielder. And in baseball the field is shaped in a diamond. The field has mark-ings, for boundaries.

    In conclusion, air pressure has a direct influence on the distance that the ball will travel when thrown. The hypothesis stated that if pressure is added to the football, then the distance the ball projects will increase when distance is a function of pressure. Based on the data that was collected from the experiment, the hypothesis was supported. When the football had more air inside, it went the farthest distance compared to the other two pressures that data was collected from.
