Results H1 H2 Landing spot ( ) Actual value (landing spot)
Trail one .26m .904m 96.96cm 96.8cm
Trail two .235m .904m 92.18cm 92cm Discussion questions
1) Equation for the landing point of the bob
2) Distance where the bob should land from directly beneath the rest position of the pendulum.
3) Would you expect the same result if you used the different mass?
If the experiment were to use a different mass the result would not differ as the length that the mass travels is independent on both the mass of the objects and the gravitational force which is acting upon it. However the landing position of the mass is dependent on the heights (h1 and h2).

The centre of where the bob lands is hard to find because you will get two maybe three indentations on the paper. This will make it hard to find the exact distance from where the bob is launched to where it lands. There when comparing the calculated result to the measured result is could cause a millimetre different between the two. (see figure 4)
How the experiment was able to be undertaken
The mass was able to be launch through the use of moment because when the string was burnt using the match stick the weight was able to be launch without any additional force required to act upon it. For example if the mass was launched with by a human there would be a risk of adding extra force upon the mass causing the landing position to change.
The projectile was able to be launched because when the string was burnt on the opposite end to the razor blade the mass was able to swing at certain velocity allowing the string to be cut causing the projectile to be launched into the air and if calculation and measurements are correct, will allow the projectiles to land in the predicted area.
