Properties of Air
What is pressure?
If I hug my favourite stuffed animal, this force is being applied.
What is compression?
What is 500 grams?
If a hang-glider is running to fly off the side of a cliff, this force of flight is at work.
What is thrust?
If I blow up a balloon and weigh it, it will be slightly heavier than a balloon that is empty. This is because air has...
What is mass?
When I use scissors, this force is being applied to cut the paper.
What is shear?
A flexible steel rope that supports a suspension bridge.
What is a cable?
As an airplane takes off, air moves faster over the wings, causing the air pressure underneath the wing to push the aircraft up. This force of flight is called...
What is lift?
If I blow air OVER a piece of paper, the paper will go...
Up!
If I twist a towel to wring out any water, I am exerting this force.
What is torsion?
These forces effect bridges the most.
What are compression and tension?
A skydiver jumps out of an airplane and deploys their parachute. They slowly float to the ground safely. This force of flight is called...
Bernoulli's principle explains how airplanes fly, because when air travels faster over the wing, the air pressure...
What is decreases?
If we play tug of war as a class, this force is being exerted on the rope.
What is torsion?
A long piece of wood or steel that supports a ceiling or bridge.
What is a beam?
A chicken flaps it's wings and can become airborne for a few seconds, but quickly falls down to the ground. This force of flight explains why.
What is weight?
The word for the shape of an airplane wing in the simulator.
What is an airfoil?
Which internal forces effect buildings when earthquakes happen? Hint: They both start with 'T'
What is tension and torsion?
These supports form triangles to help strengthen bridges.
What is a truss?
When an airplane is flying through the air (cruising) the forces of flight are...
Balanced.
