Surface Area, Resistance and Mass Experiment

Equipment

* 6 cup cake holders

* Metre Ruler

* Stop Watch

* Blue Tack

Method

======

We started by weighing a single cup cake holder, it being (0.2g.) We

dropped it from a distance of 1.84m from the ground. We then recorded

the time it took to fall. We then screwed it up and dropped it from

the same distance to see whether surface area had an effect on the

time.

After the first experiment we started investigating mass as well by

adding 0.2g of blue tack every time on 5 more cup cake holders,

repeating the screwed up and non screwed up procedure.

Fair Test

---------

This will be a fair test as it will be the same distance (1.84m) for

each occasion and will be in the same condition room with no more or

less wind. The Blue tack will be exactly 0.2g each time it is added

onto the previous weight.

Conclusion

By carrying out this experiment I have learnt that surface area plays

a great part on an object being dropped from a distance, even if the

mass of the object is the same. The greater the surface area of the

object, the greater air resistance, this is because the more surface

there is, the greater the number of particles that the falling cupcake
