The motion of these components can be described as d=vt for constant horizontal motion, and d=1/2at² + Vit. The initial velocity with no angle will be found first, and then will be used to find the distance at which we place the bin. Apparatus: You will need: -Projectile launcher -Plumb Bob -Metric Tape Measure -Carbon Paper -White Paper Setup: * Part I * Part II Part I: Determine Muzzle velocity 1. Firmly attach the Launcher Base to a table by using a C-clamp, with the “launch point” (marked on the side with a circle and a cross) hanging over the edge. Make sure the launch range is clear of any obstructions.
The following equation represents this relationship where k denotes the spring constant or stiffness of the spring, F=-kx Since x symbolizes the displacement or change in the length of the spring the above equation can now be surmised in the following manner, F=mg=-k∆l This new form makes it evident that a linear proportion exists between the plot of F as function of changing in length, ∆, thus confirming the spring does in fact obey Hooke’s Law. This enabled the group to determine the spring constant k. B. Derivation of Equations Definitions To gain a better understanding of the terms used here
Thus, a limiting reagent is the reactant that determines how far the reaction will go before causing the it to stop since there are fewer moles of it than the proportion requires. When performing a limiting reagent stoichiometry problem, one is given the starting amounts of the reactants which should be converted into moles. Next, the problem should be treated as two separate problems, and each amount of moles of reactants should be multiplied by the proportion of product to reactant. This will solve for the amount of product that can be made with each of the two different reactants. The correct amount of product that can be produced is the smaller of the two values since that reactant limits the production of product.
After the calibration, select one of unknown blocks in the shelf. In this lab, block No.5 was chosen. Use caliper to measure the length of the block and diameter of the hole. Use micrometer to measure the height and the width of block. Finally, use scale to measure the mass of the block.
These weights hang off the sides of the wheels and pull on the string at different angles, the objective is to find the point at which all the weights pull on each other so the center of the string is in the center of the force table. This was found in the lab by slowly adding weights till the right mixture was found. The forces are recorded and then shown through vectors. Adding the Vectors up shows that you have a system of equilibrium or not, depending if there is a gap between the first and last vector. The results came out to be complete vectors with the corresponding degrees of the angles with we experimented on.
4. Calculate the molarity of the commercial bleach (not diluted) using your answer from step 3 and the M¬1V1 = M2V2 equation. (Use volume of concentrated bleach and total volume of dilute bleach) 5. Assume that the density of the commercial bleach is 1.08g/mL. Calculate the percent by mass of NaClO in the commercial bleach.
Then you place another 200 gram mass on the 210 degree mark. Then we have to replace the mass at the 30 degree mark with two masses, one at the 0 degree mark and one at the 80 degree mark. Essentially we are trying to calculate the x and y component vectors of a 200g mass at 30 degrees. So what we did was we just guess and checked the variables of weight at the 0 degree mark and at the 90 degree mark’s pullys until the ring was centered. You can us+e the weight on each pully to calculate the magnitude and the direction of the component vectors at 90 and 0 degrees.
Once the results are found you can calculate the percent error of the uncertainty values. The uncertainty value is the acceleration of the ball falling down. That value will be compared to the gravity value to see how closely related they are. Introduction The formal lab “Uniform Acceleration”, studies uniform acceleration by rolling a ball down a ramp and dropping an object to calculate its acceleration. Also this lab teaches about measurement uncertainty can be calculated using the percent error equation.
These measurements are weight, which is measured by the gram; temperature, which is measured by Celsius; Newton which is the measurement of force, which is measured bykg 〖m/s〗^2. When one is making accurate measurements, one must use some sort of tool. This also applies for the Metric System of
Coefficient of Friction By Omar Ramadan Partners: Samuel Saarinen Brian Urbancic Feb 23, 2012 Abstract: The coefficient of friction is a number that determines how much force is required to move an object that is held back by friction. The goal of our experiment was to measure the static and kinetic sliding coefficient of friction between two surfaces by using a ramp and measuring its inclination. The premise is that when a solid object is placed on a ramp and the ramp is tilted upward, there is a point that the object starts to slide. That is the angle where the force of gravity is strong enough to overcome the kinetic and static friction. Once the angle, or the inclination, is known, we can then calculate the sliding coefficient of friction between the two surfaces.
