define how the wood will be chucked. When wood chucking the chuck will be spinning around the spindle and an attachment will be used that will act as a catcher that will be on the outer radius of the chuck. We will also be able to calculate the velocity of the wood leaving the chuck and the kinetic energy. Lathes & Chucks A LATHE is "a machine tool designed primarily to do turning, facing, and boring. Their versatility permits multiple operations to be done with a single setup of the workpiece
either be proportional to the velocity or to the square of the velocity. Drag force will eventually counteract downward forces on an object in freefall, resulting in a terminal velocity. The acceleration of the object can be modeled by an exponential decay graph. PURPOSE Evaluate how terminal velocity varies with mass. Determine in which instances air resistance is proportional to velocity or to velocity squared. Understand how mass influences the decay constant k. PROCEDURE (EXPERIMENT #1) Begin
The Kinetic Constants of Alkaline Phosphatase were Determined from E. coli K-12 Cells Abstract Alkaline Phosphatase (APase) is an important enzyme in pre-diagnostic treatments making it an intensely studied enzyme. In order to fully understand the biochemical properties of enzymes, a kinetic explanation is essential. The kinetic assessment allows for a mechanism on how the enzyme functions. The experiment performed outlines the kinetic assessment for the purification of APase, which was purified
Introduction to linear motion graphs The change of location of an object along a straight line and can be described using a single spatial dimension is called linear motion. It can be uniform or non-uniform, that is, constant velocity or variable velocity. The motion of particle can be described in terms of X with time T. A very good example for linear motion is a ball throwing down and up straightly. Plotting of graphs under linear motion is called Linear motion graphs. Here we study about two
spot in the bat due to the stamping of the emblem. It's Basic Physics When looking at a collision between a baseball bat and ball, three things always apply: Conservation of linear momentum- The linear momentum of a particle of mass, m, moving with a velocity, v, is defined to be the product of the mass and velocity: p=mv Elastic collision- An elastic collision between two objects is one in which total kinetic energy (as well as total momentum) is the same before and after the collision
State the relationship (linear, quadratic, exponential,…). Both relationships are
projectile motion are being made. The objective of the study is to show that velocity, acceleration and distance are related such that one is actually the slope of the other. The slope of velocity is acceleration. The slope of distance is velocity. Hence, changes in one of the factors involving a certain object, the other related factors are also inevitably altered. This exercise also seeks to prove the constant of acceleration due to gravity. The first activity utilized the ULI, photogate
Absorbance, ε is extinction coefficient or the molar absorptivity (M-1 cm-1), and l is the path length (distance) that light passes through the sample (cm), c is a concentration of solution (M) (#3 Ninfa, Ballou, Benore). Beer- Lambert Law predicts a linear relationship between absorbance and the concentration of a chemical species being analyzed. It states that the absorbance (A) of a sample solution is directly proportional to the concentration (c) of the absorbing colored
is assumed to be well defined and is initially flat to form the plane y = 0. Also, we consider that the two fluids are streaming with uniform horizontal velocities and throughout the two superposed porous media. The subscripts (1) and (2) refer to the lower and upper fluid, respectively. The acceleration due to gravity
Newtonian Fluids The fluids which obey the Newton’s law of viscosity i.e. a linear relationship between the stress tensor and rate of strain tensor(τ=μ du/dy ), are called Newtonian fluids. These fluids are represented by a straight line on a graph between the components of shearing stress and rate of strain. The slope of line is represented by material constant μ i.e. coefficient of viscosity. In general this constant is a function of material properties like temperature and density. For such fluids
earth gravity. • The friction force was calculated as the product of the mass that cause the hanger to travel vertically downward at constant speed and the earth gravity. • The force due to gravity was calculated as the product of the mass on the hanger and earth gravity. • The force to accelerate the mass was calculated as the product of the mass on the hanger and linear acceleration. • The
energy. Rockets operate using the law of conservation of linear momentum. This law states that whenever two or more particles interact, the total momentum of the system remains constant. In this case the shuttle and it's fuel can be considered separate particles. A rocket moves by ejecting its fuel out the nose at extremely high velocities (approx. 6000 mph). The fuel is given momentum as it is being ejected. To insure conservation of linear momentum, the shuttle must be given a compensating momentum
change in velocity vs. time of the cart. The angle of the incline will be increased, in order to find the correlation between the angle of incline and the acceleration of the cart. Webster’s Dictionary describes motion as “the act or process of moving”; when an object is in motion, its location changes as a result of movement. In physics, motion is defined in terms of time, velocity, displacement, and velocity. According to Newton’s first law, “An object moving at a constant velocity will remain
motion will cause it to stay on the plate because of the equation v= ωr. This equation relates the angular velocity (ω) and the linear velocity (v). When the cup is placed at the very center of the plate the radius (r) will equal zero. When zero is put into the equation for r, the right side of the equation will equal zero, leaving us with the equation v=0. Because v is the linear velocity, we can see that the cup will not move in a straight line, rather a circular
moving trolley and the learners observed the velocity of the trolley before the mass pieces were dropped on the trolley and the velocity after the mass pieces were dropped. The velocities were then compared. Momentum: Momentum is defined as the product of mass and velocity on a body. It is a vector quantity and is measured in kg.m.s-1 (M.Mann, 2013). The Law of Conservation of Momentum state that the total linear momentum of an isolated system remains constant. This means that the momentum of two bodies
experiment we learned about equations which will give us an answer to the following situations such as; object is free falling and a car which is moving on a linear track. We also learned that these equations will give us the distance traveled, the time it took to travel, the initial velocity where it started from, and the instantaneous velocity of the object. We have also learned that acceleration is referred to gravity (g) which is 9.8m/s^2 when dealing with free falling object. The purpose of this
Dee Chester in England in 1947 collapsed, it motivates the engineers for research of moving load problem. Moving loads have a great effect on the bodies or structures over which it travels. It causes them to vibrate intensively, especially at high velocities. The peculiar features of moving loads are they are variable in both space and time. Modern means of transport are ever faster and heavier, while the structures over which they move are ever more slender and lighter. That is why the dynamic stresses
Missing figures Tennis racquets with old type of strings did not allow power and control over the racquet at the same time. To get a powerful stroke player had to hit the ball with the area of racquet closer to the tip of the racquet (toe). To obtain control and to reduce vibration of the racquet, player had to hit the ball with the area of racquet called “sweet spot”, located around the geometric center of the head. NASA’s 1973 Skylab 3 mission showed that tapered strings can move the “sweet
