4.1
Key findings
●
The larger the wing area, the lesser the
distance it travels.
4.2
Explanation of key findings
●
When there is a smaller wing area, the
plane will fly further due to being more streamlined and being able to harness
the elastic potential energy from the launch and convert it into kinetic
energy.
●
Having a big wing area means having
greater lift, but much more drag. Thus, the planes will not be able to harness
the elastic potential energy and thus fly a shorter distance.
4.3
Evaluation of hypothesis
●
The hypothesis is correct that wing area
affects the distance travelled by the glider.
4.4
Areas for improvement
●
Greater detail in results
●
Build a stronger launcher as it broke
midway through experiment
