``The aim of this project is to study the possible variations of velocity that can be introduced into the helicopter from the height´´

Apparatus

paperscissors

Conclusions

We realise from the results that the hight has something to do whit the increase ofvelocity of the helicopter.

Limitations

human error in measuring

Human error in using the stop-watch



Improvements

let the eyes stay parallel with the ruler´s number

lie dow on thefloor to know when the helicopter exactly hit the floor
