block and a wooden ramp the coefficient of kinetic friction between a wooden block and a wooden ramp The design of this experiment was done by placing a rubber stopper / wooden block onto a wooden ramp and tilting the ramp at a certain degree to cause the stopper / block to move. The measurements of the vertical distance and length of the wooden ramp would be needed in order to calculate the static coefficient of the two objects. However‚ too find the kinetic coefficient of the two objects‚ the distance

The experiment was conducted at the Human Kinetics Program (HKP) Building in the University of the Philippines – Baguio. The terrain was prepared by distributing an even layer of gravel on the ground‚ and the background was covered by black cloth spanning the length of the terrain. The subject was also dressed in black to match with the background. The boules‚ jack‚ and significant joints and points on the subject’s body were marked with green bands to contrast with the background. A throwing circle

Kinetics of the Decomposition of Hydrogen Peroxide Lab Introduction: In this week’s lab experiment‚ the rate of decomposition of hydrogen peroxide forming oxygen gas will be observed and studied. Since the rate of a chemical reaction is dependent on two things; the concentrations of the reactants and the temperature at which the process is performed‚ the rate can be measured at which a reactant disappears or at which a product appears. When measuring the rate‚ the rate law will be applied. The

Matthew Saldanha Bio DCP lab-Catalase experiment Aim: To investigate enzyme kinetics‚ using different concentration of the enzyme. Hypothesis: The assay system used in the lab consists of a filter paper disc coated with the enzyme and the dropped into a papercup of substrate (Hydrogen Peroxide). As the hydrogen breaks down the hydrogen peroxide into hydrogen and oxygen gas‚ the bubbles of oxygen gas collect underneath the filter and make it

PLAN Introduction: After having built up knowledge about the kinetics of reactions I decided to do an investigation in this area. I was initially introduced to this particular reaction1 in EP6.4 and then in AA2.1. I was interested in using this reaction as a means of potentially supporting and quantifying some of the theories that I have studied along with also perhaps extending on them. Aim: Using a clock reaction I shall: Investigate the effect of concentration for each reactant and
