Principles Of Flight. Flashcards
What is speed?
Speed is the rate of change of distance
How many metres are there in 1nm?
There are 1852ft in 1nm.
How many feet are there in 1 nautical mile?
There are 6080ft in 1 nautical mile
How many metres per second are there in 1kt?

What is the definition of acceleration?
Acceleration is the rate of change in velocity. Acceleration requires a force in order to be achieved.
What is the equation for acceleration?
F= ma
What is Mass?
Mass is the quantity of matter a body possesses. The SI unit is Kg or lb.
What is force measured in?
Force is measured in Newtons.
What is momentum?
Momentum is the product of an objects mass times its velocity.
What is the equations for momentum?
P=m/v
What is weight?
Weight is the force that a mass exerts when in a gravitational field. (9.81m/s on earth).
What is kinetic energy?
Kinetic energy is the energy that a mass possesses due to its motion.
What is the equation for kinetic energy?
K=1/2mV2
Where: m = mass; V = velocity.
What is work?
Work is done when energy is transformed from one form to another
What is the equation for work?
Work = Force x Distance
Force is measured in m/s.
