Amylase is found in the saliva of humans and is responsible for the first step in breaking down starch. Starch is a polysaccharide composed of a large number glucose monomers joined together. Amylase breaks down starch by separating the glucose molecules into maltose‚ which is a two glucose-unit compound. (Morgan‚ 2008) During this experiment we investigated the influence of pH on the activity of the

The object of ball bearings (and roller bearings) is the substitution of pure rolling motion for plain sliding friction. <br> <br>Ball Bearings rely on the rolling motion of hardened steel balls to absorb loads. This rolling motion produces far less friction than the sliding motion. These steel balls are held in circular rows between an outer and inner ring‚ which have raceways‚ or slots‚ grooved into them to guide the balls. Ball bearings are available in both filling-slot and no filling-slot types

The circular kick is very effective in inflicting damage to the opponent‚ a properly executed Muay Thai circular kick has been compared by many martial artists to being struck by a baseball bat.

Volley Ball Volley ball techniques No.1. Dig/Forearm Pass: In the game of volleyball‚ the act of digging describes a pass of a hard-driven ball from the other team. In other words‚ digging is the act of stopping the ball from hitting your side of the court after the opposing team has either spiked or served it to your team. Keywords for correct technique No.1 ARMS STRAIGHT AT 90 DEGREES • Be "ready" with arms at 90 degrees from your body. • Bend at the waist - shoulders forward

Usually bouncy balls are made of natural rubber‚ ways have been discovered in which bouncy balls can be made from leather‚ plastics‚ and other types of polymers. In this experiment we created not just any regular bouncy ball‚ but one whose materials are not harmful to the environment. In other words‚ we created the perfect eco-friendly bouncy ball. The materials we used to create this eco-friendly ball were polyvinyl alcohol (PVA) and polyvinyl

Tossed Ball Project PURPOSE: The purpose for the students of the Energy of a Tossed Ball Lab involved learning how to measure the change in kinetic and potential energies as a ball moves in free fall. Since there is no frictional forces working on the ball the total energy will remain constant and the students will see how the total energy of the ball changes during free fall. HYPOTHESIS: 1. The ball has potential energy while momentarily at rest at the top of the path. 2. The ball contains

Old Dominion University PHYS 111N Experiment 10 Harmonic Motion Submitted by: Lab Partner: Lab Instructor: Introduction In this experiment we will investigate the simple harmonic motion of an object suspended by a spring that oscillates on a vertical plane and in a separate experiment was examine oscillations on a horizontal plane. In simple harmonic motion‚ the displacement from the equilibrium position is directly proportional to the force. The force generated is always directed toward
