What improvements can be made to the mass spring system experiment? |
If the spring starts to move horizontally during oscillation stop the oscillation and start again ensuring it pulled vertically downwards
Timing more oscillations for each mass reduces the percentage uncertainty in the time period
The fiducial marker should be at the equilibrium position for the masses moving past at the fastest speed where the uncertainty is the least in timing
Motion tracker and data logger can be used in place of a stopwatch for a more accurate time value eliminating random error due to the stopwatch |

What are the safety aspects for the mass spring system experiment? |
Suspended masses could cause injury if they fall Avoid this but only displacing the object by a few centimetres and don't used to lodge a load mass |
2 points |

|
What is the control variable for the mass spring system experiment? |
Spring constant of the spring being used |

Describe the graph of this experiment |
T^2 against m
Gradient of line = 4π^2/ k
Line of best fit is a straight line as T^2 is proportional to mass |
3 points |

What improvements can be made for the simple pendulum experiment? |
Use a small pendulum bob so it's easier to measure the length to centre of mass
The angle the bobb is displaced from the equilibrium position should not be greater than 15° for the equation to work
Timing more oscillations for each length reduces the percentage uncertainty in the measurementMotion
Motion tracker and data logger can be used to remove the random error of a stopwatch increasing accuracy of your values
The fiducial marker should be at the equilibrium position for the bob moving past at the fastest speed where the uncertainty is the least in timing |
