Ch 1 - Introduction Flashcards
1
Q
Distance Conversions
A
1nm = 1852m 1nm = 6080ft
1m = 3.28ft
1ft = 0.305m
1ft = 12in
2
Q
Speed Conversions
A
m/s = knots x 0.5144
knots = m/s x 1.944
3
Q
Force
A
F = ma
ISA 1 cubic metre of air = 1.225kg
4
Q
Momentum
A
Momentum = mass x velocity
5
Q
Types of Energy
A
Kinetic Energy (KE) = 1/2mv(squared)
Potential Energy
6
Q
Power
A
Work = Force x Distance
Power = Force x Speed = Work/Time
7
Q
Newton’s Laws of Motion
A
1 - A body will remain at rest or constant velocity unless acted upon by an external force
2- The acceleration will be proportional to the force applied and inversely proportional to the mass of the body
3 - Every action has an opposite and equal reaction
