simple mechanisms used to convert rotary motion into oscillating linear motion and vice-versa. The first of these is the slider-crank - a mechanism widely used in engines to convert the linear thrust of the pistons into useful rotary motion. In this lab we will measure the acceleration of the piston of a lawn mower engine at various speeds. The results exemplify a simple relation between speed and acceleration for kinematically restricted motions‚ which will discover. An adjustable slider-crank apparatus

Mass Affecting Final Velocity Name: Anlin Pereira Class: 11C The lab was conducted on 24th September 2014 Teacher: Ms. Timlin Research question: How does the mass (grams) affect the final velocity (m/s) of the toy car on a one meter ramp? Aim: To carry out an investigation to prove that factors such as mass (grams) affects the final velocity (m/s) of an object as it travels a straight line and has a constant acceleration (m/s²). Hypothesis: It is predicted that the mass of the moving object

conducted on 13th August 2008 in Machines Dynamics Laboratory. The experiment was conducted in groups of four‚ and was supervised by lecturer Mr. Mohd Azahari Johan. Conducting this experiment is for fulfilling the requirements of Applied Mechanics Lab (MEC 424). A pendulum is defined as body so suspended from a fixed point as to swing freely to and from by the alternate action of gravity and momentum. It is used to regulate the movements of clockwork and other machinery. Therefore‚ a compound

The protein concentration in bovine cells was measured by diluting the homogenate with a 1:5 ratio; 50 microliters of homogenate and 200 microliters of water. Then 5 known protein concentration samples which were 0.4‚ 0.8‚ 1.2‚ 1.6‚ 2.0 mg/ml of bovine serum were used to

Wave Nature of Light Objective: The purpose of this lab is to investigate interference‚ otherwise known as the diffraction of light. A beam of light acts a wave‚ and we are able to use equations so calculate the wavelength of the light used. The diffraction of a straight edge demonstrates that light waves bend around straight edges‚ allowing light to enter an area of shadow. When waves are superposed‚ they reinforce each other when crests are in phase and cancel out when they are not in phase
