Overview Flashcards
Force act on airplane
DRAG
THRUST
WEIGHT
LIFT
Centre of Gravity
- where the weight act
- flight and rotate around CG
- remain in certain limity for stability
Work
Force * distance [ J or Nm]
Force do work on a body when move it in the direction
in which the force is acting
Power
W/t
it is the rate of doing work, over the time
Kinetic Energy
½ m V^2
it is the energy that a body possessed for it’s motion
Potential Energy
m g h
It is the energy that a body posses in relation of the higj
Newton First Law
A body will remain at rest or in uniform motion in a straight line unless acted on by an external
force
Newton Second Law
The acceleration of a body from a state of rest, or uniform motion in a straight line, is
proportional to the applied force and inversely proportional to the mass’.
F = m * a
Newton Third Law
‘Every action has an equal and opposite reaction’
Inertia
The opposition which a body offers to a change in motion’
Acceleration
Rate of change of velocity
Acceleration = Force/
Mass
Momentum
Mass × Velocity
The quantity of motion possessed by a body
