Experiment 5.1.2 Slotted Massthrough Ticker TimerAIMTo calculate acceleration due to gravity using a ticker timer and a slotted mass. We will be using theformula v=u+at which we can derive to a=v-u/tINTRODUCTIONThe acceleration due to gravity is normally 9.81 m/s^2 we will prove this through experimentationMATERIALS Fix the mass to one end of the ticker tape using some sticky tape Set the up the ticker timer with a clamp as shown in the diagram. Using the ticker timer on itsside reduces the friction between the tape and the timer.RISK ASSESSMENTRisk Risk Level ControlHandling Electricity Low Care takenMETHOD1. Fix the mass to one end of the ticker tape using some sticky tape2. Set the up the ticker timer with a clamp as shown in the diagram. Using the ticker timer on itsside reduces the friction between the tape and the timer.3. Connect the power supply.4. Fit the tape into the timer. Hold onto the free end of the tape and switch on the power supply.5. Release the tape.6. The pull of gravity on the mass will accelerate the tape through the timer.

Perhaps could be improved by getting rid of rounding andgetting a more accurate ruler.Reliability assessment: Could be lower 1 trial as we only used 1 ticker tape instead of averaging theacceleration of all 3. Acceleration will vary due to friction from the paper and the ticker timer and the
