The Graph Of Our Experiment

Vocabulary and Paraphrase

Cupronickel: Quarter is United States coin. The value is 25 cents.

Plumage Vaned Contour:Feather is thin and soft.

Fundamental Force:Mass will effect the object fall down.

Fundamental Concept:Mass will effect the speed.

Falling Object

Conclusion

The conclusion of this project is quarters and feathers can not fall at the same speed, because we do the experiment, that show the quarter and the feather cannot fall at the same speed, and show our hypothesis is right. This project cause the motion and gravitation. If the object is heavier,then it fall faster.That is why quarter and feather cannot fall at the same speed.

Our Experiment Result

Our experiment result is quarter and feather cannot fall at the same speed, the quarter is heavier than feather,and quarter fall faster than feather. Because if the object heavier,than that object fall faster.

Problem

Our problem:Can quarters and feathers fall at the same speed?

Our Experiment Procedure

First, we found the quarters and the feathers, rules, watch.
Second, we used the rule to volume the same height, putted the quarter and feather at a same height, and then we used the watch to test the quarter and feather fall down.
Third,we wrote down all the information about our erperiment.
