What attributes does a vector have?

• Magnitude

• Direction

• Magnitude and Direction

• Magnitude and Time

Which if these is NOT a SI unit?

• Metre (m)

• Kilogram (kg)

• Kelvin

• Watt (W)

• Knot (kn)

What is the unit for navigational distance in Aviation?

• Metre

• Nautical Mile

• Kilometre

• Statute Miles

What is Newtons Second Law?

• F = ma

• The external force acting on a body is proportional to the product of it’s mass and the acceleration produced by the force

• The external force acting on a body is inversely proportional to the product of it’s mass and the acceleration produced by the force

• Every object continues in its state of rest or of uniform motion in a straight line, unless acted upon by an external force

Where does weight act through?

• Centre of Pressure

• Centre of Acceleration

• Centre of Gravity

• Centre of Weight

What is newtons Third Law?

• For every action, there is an equal reaction felt 90° clockwise

• For every action, there is an equal reaction felt 90° anticlockwise

• Newton didn't have a third law

• For every action, there is an equal and opposite reaction

An aircraft is in a turn at 30° AoB and at a constant TAS of 100kn. Is this aircraft accelerating?

• Yes

• No

A stationary object will have momentum and inertia true or false?

• True

• False

A couple is?

• Is two equal and opposite forces acting around a central pivot point

• Is two opposite forces acting around a central pivot point

• A turning force about a pivot or turning point

• Two forces acting in the same direction along the same arm

For rotational equilibrium to occur?

• There must be angular acceleration

• The sum of all moments must be zero

• There must be translational equilibrium

• The object must be stationary
