Jessica Yan Rick St. Denis, Tyler Wiseman 13 September 2012 Projectile Motion: Ball in the Bin Purpose: The purpose of the experiment is to determine the velocity of a ball launched from the Projectile Launcher device, and then to use that velocity to find where on the floor the ball will land given a specific angle. Theory: Two-dimensional motion is as it sounds, made of the two components of Vertical velocity and Horizontal Velocity. Horizontal Motion can be described as constant, neglecting air resistance, and Vertical Motion is characterized by the acceleration of gravity pulling at 9.8m/s². In this particular experiment, the total velocity will be split into the two components in order to find the time in the air, and horizontal distance from the launcher. The motion of these components can be described as d=vt for constant horizontal motion, and d=1/2at² + Vit.
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. For part c you need to find the components of triangles a, b, and c as labeled on the front bottom of my lab. You then need to find the sum all the x component and y component vectors. Then from the sum of the components you can use the Pythagorean theorem to find the resultant vector R. Data: part a experimental ax= 875g*m/s^2 ay = 980g*m/s^2 the theoretical values for ax and were

II. Procedure: Equipment needed is a large beaker, various weights, a track, two levers, a string, force sensor, scale, a car, a tuna can, a sphere, a block, and cylinders. In the first part of the lab, first we predict the theoretical buoyant force water acts on the sphere, the block, and two cylinders using the above equation FB=ρgV and the volume for various shapes is V(sphere)=4/3πR3, V(cylinder)=πR2h, V(block)=LWH. Second we measure the buoyant force for each of those shapes taking its weights in and out of water by the force sensor and the scale respectively. The difference is the buoyant force FB=Wout – Win.
Name General Chemistry 1411 Laboratory Techniques and Measurements May 16, 2013 Professor Frank Pishva Objective/Purpose: The objective of this lab, laboratory techniques and measurements is for us the student to learn about the unit systems and how it relates to measurements in mass, length, temperature, and volume. This lab purpose is to also help us learn how to combine units to determine density, conversions, and trying to become familiar with common laboratory equipment and techniques. Hypothesis/Theory: This lab is pretty self-explanatory. The only theory that could possibly occur is on data table 9, understanding the dilution process. As the dissolved sugar volume transfer increased, the mass will stay approximately the same due to the density of the water decreasing as the sugar water become less diluted.
Trang Nguyen Lab Report Chemistry 162: Reaction Kinetics Lab The purpose of this experiment: In this experiment, students aim to determine the rate law of the reaction by finding the time for each trial of different runs occurring. Upon studying initial reaction rates at varied reactant concentration, students will give out conclusion about the effect of the concentration towards the reaction rate. Next, the effect of the metal ion catalyst on the reaction rate will be studied by adding a dilute Cu(NO3)2 to the reaction. Finally, students will determine the effect of temperature on the reaction rate by carrying out the reaction at different hot and temperature, then calculate the activation energy. The procedure: Cabasco-Cebrian, T.; Loftus, C.; Schulz, J.; Villarba, M.; Wick, D. “Lab Manual for CHEM 162” Winter 2011, Department of Chemistry, Seattle Central Community College, pp.
Because we didn’t count the proper number of significant figures in the volume we had too many when we went to calculate the density. Conclusion: In this experiment we were supposed to be able to identify unknown substances using physical properties. We were successful in understanding how the use of physical properties better helps when identifying various unknown substances. Because of this experiment I learned how to take weight calculate volume density solubility and specific gravity. We were able to determine that the unknown substance was methyl by using its boiling point and other physical characteristics.

Also this lab teaches about measurement uncertainty can be calculated using the percent error equation. These are the purposes of the lab. My hypothesis of this experiment is that the velocity of an object, the ball rolling down a ramp or falling down, changes at a constant rate, thus uniform acceleration occurs. Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity over time. An object accelerates if its velocity is constantly changing, also known as speeding up or slowing down.
