Forces
When an airplane lands on the ground, what is going on with thrust and drag?
The thrust is less than drag.
What needs to be increased in order for the plane to take flight
lift and thrust
What is the body of glider
fuselage
How does an aircraft take off
engine, turbine
What was our problem?
carrying cargo to places with natural disasters
When an airplane takes flight what is happening with lift and weight?
Lift is greater than the weight
What needs to be decreased in order for a plane to take off
weight and drag
Canard, hex, rectangular
How do airplanes and other aircraft fly?
Engines, turbine, blades, wings
What did we need to fulfill?
We needed to carry cargo over
What is that force that brings things down to Earth?
Gravity
The aircraft must overcome drag with what in order to take off
wings
delta, elliptical, straight, swept
How does the wing shape or size of the glider affect how it flies?
The wing shape or size can change or glider's energy.
What is an obstacle?
Problem/constraint
How would you know if forces are balance or unbalanced?
Forces are balanced when the forces acting on an object are equal in size.
The aircraft must overcome weight with what to take off
lift
How is a glider stable in the airplane?
When an aircraft is cruising, what happens to the forces?
Forces become balanced.
Name an obstacle
Weight, time, amount of cargo
When a glider lifts through the air, is lift and weight balanced or unbalanced?
The lift and weight forces are unbalanced. Lift is greater than weight to rise.
Who invented gravity
How is a glider different from an aircraft?
A glider is an aircraft with no engines and does not need to have its own thrust.
How did adding weight in the form or paper clips or binder clips change the flight of your glider?
Made it heavier
