Center of mass

In the second part of “Wonder” we read in Via’s point of view. Via’s point of view tells how, Auggie, got this deformation. In part two there is a chapter called Genetics 101, and a chapter called The Punnett Square. In these two chapters we read the possible of Via and Auggie having the chances of getting kids like Auggie. In this part it tells the same days Auggie is having in part one, but the way she is seeing and living the days. In the first chapter of the second part, Via tells us that Auggie is the center of attention. The way Via decribes this by saying, “August is the Sun. Me, Mom, and Dad are planets orbiting the Sun. The rest of our family and friends are asteroid and comets floating around the planets orbiting the Sun.” (page 82). When Via says, “The galaxy is changing. Planets are falling out of alignment.” (page 83). What Via meant is that Auggie is going to school, so…

their takeoff (Alexander, 1990; Dapena 1992). Upon launch the objective is for the athlete to have their back entirely to the crossbar at the height of the jump, and their head and feet drooping over as their hips clear the height. This is commonly referred to as the arch or layout (Burns, 2013). High jump can be divided into three phases: the momentum building or run-up phase; the takeoff, launch or flight phase; and lastly, the bar clearance phase (Dapena, 1992). The run-up helps the athlete…

What makes a good rocket? Many things go into making the perfect rocket, but just what are they? That is what Colin Robinson and Heidi Hall set out to find out. The first thing that had to be tested was the ideal mass of the rocket. A lot of the rockets distance depends on the mass and the area. Another variable that had to be tested was how many fins to use based on the ideal mass for the rocket. In a rocket it is normally true that it will fly the farthest if the mass is closer to the front,…

evel the force table and put one of the pulley at the angle 35° and another at 150° Place .100 slotted mass on a weight hanger at 35° Place .200 slotted mass on a weight hanger at 150° Place another pulley at different angle from 35° and 150° On the third angle, place the amount of slotted mass so the ring will remain in center of the force. Now the ring is at equilibrium. Record the required slotted mass that made the ring at equilibrium. Record the tensions in each of the strings on the…

of an extended object. However, there is one point, associated with the geometric mean center of the mass distribution of an extended system, known as the center of mass, always behaves like a point particle as if all the external forces, and the mass of the entire system, are on that point. In this view, all the…

Suhani Shah & Emma Bekhet Purpose: To develop an efficient and accurate method of using torque to mass a meter stick – without using a triple beam balance or spring scale / force meter. Materials: One meter stick One fulcrum Three sliding Clips One 50 gram hanging mass Procedures: Setup fulcrum Attach a sliding clip at the 50 cm mark of the meter stick and place meter stick on a fulcrum. From that point, move the sliding clip left and right (based on which side of the meter stick is…

two stances are called the ‘feet-apart’ pose and the ‘feet- together’ pose as shown in Figure 1-1. An angled-body posture, by displacing the center of mass both forward and downward, can help reduce the amount of torque that the pushing ankle needs to counteract. The statically displaced center…

The instability of the roller coaster creates a spring constant. This means that as the car travels through the roller coaster, it loses energy because the track shakes and moves. For example, when viewing the videos it became apparent that when the car entered the loop, the track shook violently making it difficult to determine when the car reached each location. As the car went through the track, going up into the loops it grew in height, decreasing in kinetic energy while increasing in…

The foot and ground exert an equal and opposite force on each other. This is known as the ground reaction force.12 The position and acceleration of the runner's center of mass regulates the direction and magnitude of the ground reaction force. For instance, a runner sprinting from a standstill. Throughout the initial phase of acceleration, the body is inclined forward and therefore the center of gravity falls in front of the contact surface. After many gait cycles, the runner reaches top speed…

Lab 3: Technology Name: Section: General Physic Lab 3 Date: 10/03/2017 Purpose The goal of this experiment was to learn how to apply computerized instruments in physics. In addition, this experiment aimed at enhancing practice on how to use three equipment in the lab: the rotary motion sensor, high resolution force sensor, and motion sensor. Further, this experiment sought to clarify the circumstances under which the instruments fail to comply with expectations. Results/Data Part 1: The…
