### What is a "rapid changes in gravitational force"

Relativity states that the so-called force of gravity is not a force, but an acceleration due to the distortion of space time. There is no physical difference in between gravity and acceleration, or ...

### What is a "rapid changes in gravitational force"

g-force or load factor $n$ = (total acceleration minus the acceleration components due to gravity) / g. It is an acceleration expressed in g-units, or multiples of 9.81 m/s^2. In the equation $n_z$ = ...

### What is a "rapid changes in gravitational force"

In short BBC describes the force variation on persons and objects during the turbulent/windshear event. They say the magnitude was subject to rapid changes. This force is sometimes called the g-force, ...

### What is a "rapid changes in gravitational force"

The TSIB preliminary findings and the BBC use "G" as a short-hand for g-force, which is not the same thing as "gravitational force". They are using the wrong terminology here. The ...

### In a straight and level flight if thrust is equal to drag how is aircraft moving forward?

Drag is produced by moving through the air- more speed means more drag. Thrust is the motive force that pushes the plane through the air- more thrust means more push. At cruise, push equals drag and ...

### In a straight and level flight if thrust is equal to drag how is aircraft moving forward?

Per Newton's first law, A body remains at rest, or in motion at a constant speed in a straight line, except insofar as it is acted upon by a force. You need excess thrust to get up to speed. But ...
