What the Centre of gravity is why is it important?
Therefore the location of center of gravity is an essential parameter to determine the flight characteristics of an object. Controlling the flight of an object necessitates good knowledge of its center of gravity location. The lower the center of gravity is, the more stability the car or truck has.
Why CG center of gravity is very important when solving the weight and balance?
The center of gravity (CG) of an aircraft is the point over which the aircraft would balance. The center of gravity affects the stability of the aircraft. To ensure the aircraft is safe to fly, the center of gravity must fall within specified limits established by the aircraft manufacturer.
Where is center of gravity in human body?
Normally the center of gravity of a human is about an inch below the navel in the center of the body. How is this location affected by changes in body position such as bending over?
What is the difference between centroid and centre of gravity?
The center of gravity of any object is termed to the point where gravity acts on the body. Where on the other hand, the centroid is referred to as the geometrical center of a uniform density object….

Why is it important to know the center of gravity?
It is important to know the centre of gravity because it predicts the behaviour of a moving body when acted on by gravity and it is also useful in designing static structures such as buildings and bridges. In a uniform gravitational field, the centre of gravity is identical to the centre of mass. Yet, the two points do not always coincide.
Why is it important to manage the CG?
Is it primarily due to fuel penalty, or take-off and landing performance, or is it mostly just to keep the aircraft from tipping over during loading and unloading, or other? As a bonus, does tipping over of aircraft actually occur these days due to improperly managed CG?
What happens if the CG is ahead of the center of lift?
If the c.g. is ahead of the center of lift, the aircraft will pitch down. The pilot can counteract this by pulling on the elevator, which in effect reduces lift at the tail and thus shifts the center of lift forward. As you can imagine, there is only so much lengthwise change which can be effected with the elevator.
Why is the CG position of an airplane important?
So the first limit for the c.g. position is given by controllability. Another important consideration is stability. You want the airplane to return to the original flight attitude if it has been disturbed, say by jolt on the stick or yoke.
