Experiment 37: Friction Anne Smolinski as910513@ohio.edu Wednesday 11:50-1:40 TA: Sanjoy Sarkar November 11, 2017 Experiment 37: Technical Report ABSTRACT In experiment 37, the friction force is being explained and tested by using a block that is being pulled across a wooden base. Out of the four different types of friction, two will be tested during this experiment: (i) static and (ii) kinetic. Static friction can be defined as the force that resists motion of an object to a surface so…

1.1. Mechanical properties of CP/CNF and CP/CNF/ZIF-67 1.1.1. Stress–strain curves The stress–strain curves and the effects of CNF dosage on the tensile strength, elastic modulus, and elongation at break of CP/CNF and CP/CNF/ZIF-67 are shown in Fig. 3 and Tables S1–S4. As shown in Fig. 3(A) and Table S1, the tensile strength, elastic modulus, and elongation at break of neat CP is 7.37 MPa, 996 MPa, and 3.07%, respectively. After coating and crosslinking with CNFs, the mechanical properties of…

The speed of light is the ultimate speed limit in the universe. Which travels at 3.0 x 108 m/s in a vacuum and always moves in a straight line. When light travels to a new medium its speed and 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…

When people think of Isaac Newton and the contributions he made to science they usually think of his law of gravitation, but there is so much more. He came up with the three laws of motion, theory of light, and the universal law of gravitation. Newton transformed the history of science. In the first three years when Newton was at Cambridge, he, like everybody else, was taught the standard curriculum, but he was more interested in the advanced science. (Isaac Newton, 1) One of his very first…

Mathematicians have been around for centuries. They have contributed great amounts of knowledge to the world. A mathematician is a person who excels or is an expert in mathematics. One specific mathematician that brought great ideas into the world was Gottfried Leibniz. He contributed a lot to mathematics, science, physics, philosophy and even his local government. Mathematicians are very important because without them we would not have many important theories that explain why certain things…

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…

Evangelista Torricelli was a great scientist in the times of the Renaissance. At a young age, Torricelli lost his father. He went to study with a Camaldolese monk and also his uncle, Benedetto Castelli. It was there when he was taught mathematics, mechanics, hydraulics, and astronomy. In return of all the gifts he received, Torricelli became Castelli’s assistant. Torricelli became increasingly more interested in astronomy, but chose to pursue mathematics as he saw how Galileo, his idol, was…

As many people may know, Isaac Newton was a man of many talents, but he was most famous for his law of gravitation. As a result, he played a significant role in the scientific revolution of the 17th century. Isaac Newton became one of the most influential scientists in that century. He invented reflecting lenses for telescopes which produced clearer images. During his life, he went through many hardships. He had a mental breakdown before losing his mother in 1678. Isaac Newton transformed the…

Newton’s Laws Sir Isaac Newton, the man who developed the first theories of gravitation, also introduced the three laws of motion. These laws essentially changed the field of physics in an astounding manner – it paved the way to modern science. Let’s look at these laws in some more detail: Newton’s first law: It states that an object will remain at rest or in a uniform motion, unless an external force acts on it. This is basically also the definition for inertia. In other words, the state of…

There are six fundamental movements or primary movements which occur where the joints 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…
