   Flight

Questions:

Does the weight affect how good the plane flies

Research Summary:

To get a plane to actually fly and not have a falling object from the sky you’ll need four components: weight and lift, thrust and drag. 

Lift force upwards = weight force downwards (so the plane/bird stays at a constant height)

thrust force forwards = opposing force of drag (so the plane/bird stays at a constant speed). 

The force working against thrust is called drag. It is caused by air resistance and acts in the opposite direction to the motion. Thrust can overcome or counteract the force of drag. Planes and birds have to be able to provide enough lift force to oppose the weight force. Lift is a force that acts upwards against weight and is caused by the air moving over and under the wings.

Hypothesis:

I think that the plane that has more weight won’t fly very well because there is more drag.

Materials:

Paper

Tape measure

Procedure:

1. Get a piece of paper

2. Watch a video on how to make a plane

3. Get a tape measure 

4. Find a place to fly your plane

5. Fly your plane

6. Measure the distance

7. Write down how far it went

8. Repeat 3 times

Controlled variables	Independent variables	Dependent variables
size	weight	distance

 

Observations/Results:

Throws	1	2	3
1  paper clip	10.5 m	8.6 m	7.2 m
3 paper clips	5.8 m	5.6 m	5.2 m
5 paperclips	4.7 m	3.8 m	3.2 m

Discussion:

My experiment went well because the hypothesis was correct.
