Chapter 1 - Units / Basics Flashcards
How many metres in a Nautical Mile?
1852m
What do we call the rate of change in distance?
Speed - scalar
If a rate in change has a direction what do we call it?
Velocity - vector
If you to get metres per second fro knots what is the equation?
knots x 0.5144 = m/s
As a quick way we can divide knots by
in half to get m/s
what 1 m/s in fpm
196.8 fpm
equation for acceleration?
F = ma
How do we convert kg to pounds
x 2.205
Momentum =
p = mv
Force is measured in
Newtons
Weight has a force action upon it, usually?
Gravity = 9.81 m/s
Weight must be always expressed in?
Newtons
Energy is expressed in
Joules
Kinetic energy =
1/2mV^2
What must the total energy always be?
Constant
When an aircraft is in flight what posses the kinetic energy
the air mass moving
What is the equation for Work and measured in?
Work (Joules) = Force (N) x Distance (m)
Power =
Work/ time
An aircraft on full thrust with brakes on =
No power
In straight an level flight which Newtons Law are occurring?
1st & 3rd
In a turn or change of directions which Newton Law is occurring?
2nd
