Purpose/ Hypothesis: The purpose of the lab is to explore some of the variables that influence projectile motion using a Rubber Band Cannon and launching rubber bands and measuring its horizontal distance and angle at which the rubber bands has been launched.. Materials: Materials used for the lab were a Cardboard Box‚ a 30cm ruler‚ rubber bands‚ a measuring tape‚ tape‚ a pencil‚ a paper protractor cut out‚ and scissors. Procedure: For the lab‚ scissors were used to cut the paper protractor cutout

Motion in a Viscous Medium Aim The aim of this experiment is to measure the terminal velocity of spherical beads falling under gravity in a liquid determine‚ and hence determine its viscosity using Stoke’s law. Introduction When a stationary solid object is complete or partially immersed in a fluid‚ it experiences an upthrust or buoyant force. According to Archimedes’ principle‚ this buoyant force B is given by where ρ is the density of the fluid‚ Vs is the immersed volume of the

LAW TONG &AIDEN 2013/9/23 AP PHYSICS B Mr. Moss THE LAB OF ATWOOD Procedure: The purpose of this experiment was to verify the predictions of Newton’s Law for an Atwood machine‚ a simple machine constructed by hanging two different masses and from a string passing over pulleys and observing their acceleration.. Newton’s Law predicts that the acceleration should be proportional to the difference between the masses and proportional to their sum‚ where = 9.8 m/s2 is the

Various types of sporting equipment are constructed with springs and elastics‚ in order to absorb a force or apply a force to another object. In the context of this investigation‚ the spring is utilised to propel an object. According to Hooke’s law

Brownian motion This is‚ presumably the random drifting of particles suspended in a fluid (a liquid or a gas) .This movement was discovered and later named after botanist Robert Brown (1773-1858). He was a Scottish botanist and palaeobotanist who made important contributions (including Brownian motion) to botany largely through his pioneering use of the microscope. The scientist who made Brownian motion famous is Albert Einstein‚ who brought the phenomenon to the attention of the larger physics community
