Unit 1 Assessment

Which of Newtons laws best describe Rocket Launch?

• Every object moves in a straight line unless acted upon by a force
• The acceleration of an object is directly proportional to the net force exerted and inversely proportional to the object's mass
• For every action, there is an equal and opposite reaction

True or False: Gravity only affects objects in free fall, not those in flight.

• TRUE
• FALSE

This part of the wing creates drag and lift and allows the plane to fly more slowly.

• Flaps
• Ailerons
• Vertical Stabilizer
• Horizontal Stabilizer
• Slats

This part of the plane moves along the longitudinal axis (roll). They help to turn the plane.

• Ailerons
• Vertical Stabilizer
• Horizontal Stabilizer
• Flaps
• Slats

This part is on the vertical section of the tail. It moves side to side on the vertical axis (yaw).

• Rudder
• Ailerons
• Vertical Stabilizer
• Horizontal Stabilizer
• Flaps

The part of the tail that moves on the lateral axis. When it goes down, the plane goes up.

• Elevator
• Ailerons
• Vertical Stabilizer
• Horizontal Stabilizer
• Flaps

The pilot needs to make an emergency landing, but first needs to turn the plane around with the use of a Rudder and Ailerons. If the pilot is trying to roll the plane to the RIGHT, how will the ailerons engage during the flight?

• Flaps and Slats will open and the rudder will turn right.
• Right Aileron will be lowered and left Aileron will be raised.
• Left Aileron will be lowered and right Aileron will be raised.
• Rudder and Elevator will both be lowered.

How does an airplane generate lifts?

• The difference in pressure creates a force on the wing that lifts the wing up into the air.
• The use of ailerons and rudder will equalize the forces during a lift.
• The thrust generated by the turbines will increase the drag causing the fuselage of the plane to rise.
• Flaps and slats reduce the forces responsible to lift the plane.
