Air and Energy Forces Crossword Puzzle

QUESTIONS LIST:

• airfoil: the wing of a plane.
• altitude: air pressure decreases with higher _ , allowing an airplane to move at higher speeds.
• bernoulli: a swiss mathematician and physician who discovered the basic concept of flight
• drag: resistance that slows an object down in the air. items that are streamlined have less drag in air.
• flaps: the flaps slide back and down to increase the surface of the wing area.
• force: a push or a pull that causes an object to undergo a change in speed, a change in direction, or a change in shape.
• fuselage: the body of the plane
• gravity: a force that pushes objects come down to the earth.
• lift: a force that pushes objects upward.
• pitch: making the plane go up or down (elevator controls). the elevators on the tail to make a plane descend or climb. lowering the elevators caused the airplane's nose to drop, sending the plane into a down. raising the elevators causes the airplane to climb.
• roll: moving the plane vertically, left to right (aileron controls). the ailerons are raised on one wing and lowered on the other. the wing with the lowered aileron rises while the wing with the raised aileron drops.
• thrust: the force of flight that pushes a plane forward. the engine provides the thrust for flight.
• weight: a force that acts on the plane to pull it back to earth.
• wing: also called airfoil. the wings provide the lift for the plane.
• yaw: moving the plane horizontally, left to right (rudder controls). when the rudder is turned to one side, the airplane moves left or right. the airplane's nose is pointed in the same direction as the direction of the rudder.
