Scientific method

aerodynamics

the study of how gasses flows over moving objects

air pressure

the force exerted on the surface of objects by air particles

Bernoulli’s Principle

helps explain how an airplane can achieve lift because of the shape of its wing. Air flows faster over the top and slower underneath. Fast air = low pressure, slow air = high pressure. The high pressure lifts the plane up.

drag

the force of resistance or friction that slows down and object moving through the air

flight

the action or process of moving through air

friction

a force acting between two objects that stops or slows down movement

gravity

the pulling force that attracts objects together

launch

to start or set in motion

lift

the upward force created by the shape of an air crafts wings moving through air

mass

the amount of matter in an object

thrust

the force that moves and airplane forward

weight

the measure of the strength of the pull of gravity on an object

question

what you want to learn more about and get an answer to

research

garthering information about the outcome of an experiment. A hypothesis can also be explained as a statement that predicts an outcome to an experiment.

experiment

a procedure to test your hypothesis

analysis

use your data and observations to draw conclusions about your experiment and hypothesis.

conclusion

was your hypothesis correct

variable

anything that can change or be changed

independent variable

the variable that you change. There can only be one independent variable.

dependent variable

the variable that is observed,the variable that is affected by the change.

controlled variable

the variable that are kept the same

qualitative data

data/information that is observed (taste, feel, appearance, smell etc..)

qualitative data

data that is collected by counting or measuring
