Body mass index

to catholic school from Preschool to 8th grade, with mass on every Tuesday and on Holy Days of obligation. However, as I transferred to a public high school my entire extended family started to drift away from the church. We listened as sermons became increasingly related to donating more money to the Catholic Church, and watched as it out casted and judged others while preaching about not engaging in that activity. While we haven’t attended mass in over 6 years, I still believe in God and…

Proportional reasoning is a kind of mathematical reasoning that encompasses a logical comprehension of various evaluations and co-variations. Proportional reasoning allows an individual the ability to reason mathematically and is a demonstration of how a number of pieces of information are stockpiled mentally. We deal with diverse proportional information on a daily basis, such as reading temperatures, relational spatial contrast, and calculations of densities all of which is central to…

direction will change, this is called refraction. Materials have different optical density so light rays travel at different velocities. Refractive index is the ratio of the speed of light in a vacuum to the speed of light in a medium. Calculated by the velocity of light in vacuum divided by velocity in a medium. If a medium has a high refractive index ( more optically dense) the more the light will be slowed by the transparent substance. When light travels through a less optically dense…

Put one leg in front and one back to achieve this posture. Flex the body through the knees and lower the hips as well to put pressure on the hamstrings. Reverse the direction when you have descended to stand back up. Quickly jump again to perform the squats with alternating feet position. Standing Hamstring and Calf Stretch Use a belt or a band and place it around one foot. Now put this foot slightly ahead of the body. Now bend the other leg while keeping the banded leg straight. Raise this…

Did you know parachutes come in all kinds of different shapes? The shapes vary from circles to triangles. However which one is the fastest? There are many factors that effect the speed of parachutes. Kinetic and potential, for example, influence the parachutes speed and movement. When a skydiver jumps out of an airplane gravity pulls him towards the ground and he doesn’t have enough air resistance to safety land on the ground. That’s where the parachute comes in! When the skydiver pulls the…

Biomechanics is the study of the body as a machine. This study of the body looks at the internal and external forces that act on the body and the movements that these forces produce. By grasping biomechanical concepts, it enables us to programme our bodies to correct technical errors, reduce injury, move our body with precision and understand the importance of equipment design. This can be used in all sports including volleyball. I will be analysing myself and how I compare to a professional…

constant mass of the object multiplied by the change in its velocity over time (acceleration). Mass times velocity is also known as momentum. When it is mentioned that momentum changes over time, it is the exact same concept as mass times acceleration. The formula for Newton’s second law is…

are located between the body segments. These movements are flexion (frontal plane, and shoulder) extension, abduction, adduction, rotation, and circumduction. As explained in our text, flexion is a decrease in the angle between two body segments, whereas extension is an increase in the angle between two body segments. Abduction is a movement away from the body, whereas adduction is a movement toward the midline of the body. The rotation is the circular movement of a body segment around a…

proportional to the mass of the object given the same force.” (Kingaby). Kicking a soccer ball is fairly easy, mostly because light air is inside. All the ball needs is a little tap and it begins to move. Kicking a soccer ball sized rock is much more ineffective. The rock receiving a little tap will not do anything at all. The rock’s mass is much greater than that of a soccer ball, therefore it will take more force to accelerate the movement of the rock. The mathematical equation “Force = Mass ×…

At market day or day forty-two the disparity in total weight is large at almost seventy-five kilograms. Total body weight gives only a partial image of the difference and in order to see the full scale of the difference processed hot carcass weights and breasts weights must be examined. Graph 2 below contains the data for carcass and breast weights. The difference…
