May 06, 2018 this aerodynamic jump is similar to cg jump, but calculated differently - mccoy shows how. the most productive way to go about using these numbers, if you ask me, is to calculate the bullet's sensitivity to aerodynamic or cg jump. you can boil it down to a single number for a given bullet and twist rate. details are in mccoy's.
Near the surface of the earth, the acceleration of all objects due to gravity is the same. drop a penny and a pen from the same height and they will hit the ground at the same time. when objects travel down an inclined plane, gravity is pulling them downward, but the plane is exerting a force on the object, which makes it fall along the plane.
Neat facts about the center of gravity. fact 1 - an object thrown through the air may spin and rotate, but its center of gravity will follow a smooth parabolic path, just like a ball. fact 2 - if you tilt an object, it will fall over only when the center of gravity lies outside the supporting base of the object. fact 3 -.
No , the center of gravity is in a spot where balance is achieved, if an object is dimensionally heavier on one side, then the center of gravity would not be in the measurable.
