• what equipment is needed to measure fmass,force and acceleration

  • a trolly - an object used to measure accleration
  • light gate - to time trolly between intervals
  • meter ruler to measure areas of distance
  • pencil to mark areas of distance
  • weights to provide a force
  • string to attach weights to trolly
• what are the variables for the trolly mass, force accleration pratical

  • independant - mass
  • dependant - accleration
  • control - force
• experiment

  • use meter ruler to measure intervals on bench
  • attach pulley to end of bench and attach trolly to pulley using string and tie mass hanger at other end
  • select a weight on the weight hanger that will accelerate the trolly forward forward which creates a constant force on the car that won't change
  • hold the car at the standing point and use a timer to record
  • measure the time at each interval and record steps in table
  • repeat with varying masses
• important things about experiment

  • dont stand directly beneath mass hanger Incase mass falls off
