Hey guys
We are going to be doing an experiment in Science
Aim: To investigate the relationship between wing size and drag.
What is friction? Friction is a force that acts against the motion of an object.
What experiment are we doing?
- Cut out and assemble the four helicopter shown on the opposite page. Attach the paper clip to one of the helicopters.
- One member if your group holds the helicopter at a height of 2 metres.
- On the count of three, the person holding the helicopter drops it, while another member of you group times how long it takes for the helicopter to hit the floor.
- Record your results in the table below.
- Repeat each drop three times.
- Repeat steps 2-6 using the other helicopter models.
Hypothesis:
3cm: I think this one is going to fall to the floor the fastest
4cm: I think this one is going to fall to the floor the second fastest
5cm I think this one is going to fall to the floor the second slowest
6cm I think this is going to the floor the slowest
6cm: 1.53
5cm: 1.78
4cm: 1.69
3cm: 1.84
Conclusion:
In this investigation, I found that as wingspan of 6cm, the time to fall also was 1.53. This means that having a bigger wingspan increases the drag (friction created by ___). We made our results more reliable in this investigation by doing multiple times.
One thing that went well was: Measuring the time the helicopters fall
One thing we could have done to improve is: Making the helicopters more better
