Gravitational Forces Flashcards
What is “g” ?
The measure of magnitude of an acceleration force with respect to gravity
What is “G”?
Unit of measurement that is a dimensionless ratio of both force and acceleration
Applied to pilot during meneuvers
The true axial reference system is used when identifying what G forces are being applied.
What is acceleration?
Rate of change of velocity with respect to time.
What are the types of acceleration?
Linear, radial and angular
What is deceleration?
Reduction in the velocity of a moving body to time
What is inertia?
The resistance to change in the state of rest or motion
What is Newton’s first law of motion?
A body at rest tends to stay at rest, a body in motion tends to stay in motion until acted upon by an outside force
What is Newton’s third law of motion?
For every action there is an equal and opposite reaction
What is the difference between centrifugal force and centripudal force?
They are opposites
What are the factors of acceleration?
(BIRDI)
•body of area and site
•intensity
• rate of onset
• duration
• impact direction
What is body and area site?
The greater the size of the body area affected, the less sever the effect
What is intensity?
The greater the intensity, the more severe the effects of accelerative forces
What is rate of onset?
The faster the rate of acceleration, the more severe the effects
What is impact direction?
Force in Gy axis will not be tolerated as well as force applied to another axis
What are low magnitude accelerations?
G’s that range from 1-10 lasting for several seconds
