In the above table, the third point of period distance will be considered as a random error.

Aspect 2:

1. Calculating the period time:

TP = Number of Frequencies  image00.png

        Period Frequency image01.png

TP =            1

           (30.0 + 0.5) s-1image02.png

TP = 0.0333s

EP = 0.0333s ( +0.5s-1 / 30.0s-1 )

EP = +0.0006s

2. Calculating the speed:

v = distance / time    image03.png

= (0.016 + 0.001) m / (0.0333s + 0.0006) s

= 0.048048ms-1

Ev = 0.048048ms-1 (( + 0.0006s/0.0333s) + ( + 0.001m/0.

Conclusion

There were not any other errors caused by the apparatus. It was stable enough for the experiment. Therefore, there is no need to change the apparatus if this experiment would be done again. However, some other materials could be used such as the mechanical device that distributes equal force to both sides of the puck and make the puck go straight. This will bring improvements to the accuracy of measurement.

    This is obviously impossible as an object cannot accelerate without force applied. It is obviously that there are errors in this experiment that cause this problem. Indeed there are several systematic and random error. The main systematic error is neglecting the effect of frictional force on the moving object.

    Molecules do not speed up during a phase change. Evaporation differs from boiling as evaporation is a change from the liquid state to the gaseous state that occurs at a temperature below the boiling point. Specific latent heat is the amount of energy per unit mass absorbed or released during a change of phase.
