Center of mass

would be the surface of earth. Then to find out how far away from the Earths surface area you would have to be to be 1/16 of your weight you would multiply the surface area by 16 and get 8,235,496,645 km away. • The sun’s mass is about 2.7 x 107 times greater than the moon’s mass. The sun is about 400 times farther from Earth than the moon. How does the gravitational force exerted on Earth by the sun compare with the gravitational force exerted on Earth by the…

As mentioned before, pitching requires several joints and muscles. Shoulder and elbow are two of the joints that are involved in the movement. Of the six phases of pitching, arm cocking, acceleration and deceleration are the three phases when elbow and shoulder joints experience high magnitudes of forces (Oyama 83). Windup is the phase that occurs when the pitcher places the non-throwing hand is in front of the target. In the beginning of the arm cocking phase, the non-throwing shoulder is…

Forces are extremely important in a roller coaster, as they create the different sensations throughout the ride, and also help to hold you in your seat for safety. Forces on a roller coaster are measured in g's, which is how to measure gravity on the ride. The change of g's in different situations is what creates the different feelings and thrills you get on the coaster. When our marble is released at the top of the initial hill, energy is transferred from potential energy to kinetic energy.…

Differences in thermoregulation patterns observed in the Monarch Butterfly, Danaus plexippus Many Lepidoptera species thermo-regulate using several patterns, physical and behavioral. These patterns are usually observed as movements from the shade and cooler areas to a place exposed to the sun as well as utilizing mechanical flight to generate heat. However, some species have intermediate behavioral patterns, often a mixture of basking and heat production, also known as endothermy (Kingsolver…

Have you ever needed to do a certain simple task, but wished there was a machine to do it for you? The purpose of a Rube Goldberg machine is to create a complicated system in order to complete a tiny, simple task. What is a Rube Goldberg machine you may ask? A Rube Goldberg machine is an over- engineered contraption that uses a chain reaction to accomplish simple tasks such as turning on the music, pouring a glass of water, etc. This specific Rube Goldberg machine’s task is to move the last…

I visited the Saint Williams Catholic Community in Shelbyville, TN, on March 5th at the 9:00 bilingual mass. I chose this experience because I have had several Spanish speaking students' in the Pre-K program that I am currently an assistant teacher for. I wanted to better understand the culture of my students, outside of an environment where I am deemed to be dominant. I also wanted to see how different the Catholic church setting is from what I am use to. I have passed this…

The teardrop design makes it much easier to balance these forces. the only forces exerted upon the riders are the force of gravity and the normal force The force of gravity is at all times directed downwards and the normal force is at all times directed perpendicular to the seat of the car. Since the orientation of the car on the track is continuously changing, the normal force is continuously changing its direction. Feelings of weightlessness and heaviness are associated with the normal…

Differential Services When a car makes a left turn, the left side wheels naturally turn slower than the outside wheels on the right because the exterior wheels have to travel farther than the inside wheels make the turn. For this reason, tires have to be able to move independently and at different speeds to avoid slipping. This gives the car more power and control in the turn. A differential is a mechanical set of simple gears that allow the wheels to rotate at independent speeds, and to be…

During the 17th century, an English scientist Sir Isaac Newton showed the scientific research for rocketry. Newton represented his idea of motion into three different laws. These explained how rockets work and why they work in space or any other sort of mediums. The first movement law is an object in motion will stay in motion unless acted upon by another force. The second law states, acceleration of an object is exerted by a net force is directly proportional to the magnitude of the net force.…

For my orthographic drawing, I created three different views of my putt putt boat. I created a top, front and side view of my boat. I created an orthographic drawing because it accurately shows the top, front and side views clearly and more precisely. I was representing a 3d object in 2 dimensions. My three views show how each side of the boat looks in detail and the accurate measurements of the boat. To create the hull, we shaped a piece of aluminum into a “pocket” by using sandpaper to sand…
