The motion of a body will be being drawn towards the center of the earth where it is sugested gravity is centered. Our moon is being drawn towards the center of the earth, but because of its speed around the earth it always continues to fall towards it but never actually reaches it.
In general, the body will accelerate toward the source of the gravity (another object or group of objects) with acceleration = G x Ms / r2, where G = gravitational constant, Ms = mass of the gravitational source (other object) , and r = distance between the centers of mass of the two bodies. This motion will be added to any existing motion the body has already.
What about it? The question is very vague but i hope this answers it. The object will move towards the body producing the gravitational force at a velocity that can be determined by F=MA (Newtons second law)
If air resistance is negligible then an object will fall with an acceleration due to gravity which is on average 9.8 m/s/s.
downward motion
It is said to be in free fall.
free fall
It falls
The equation of motion is not modified. Net force = mass x acceleration, whether freely falling or not.
Accelerated motion.
You're probably thinking of the term 'free-fall' or 'freely falling', or in relativity you might say it follows a 'geodesic'.
gravity
A feather falling in a vacuum is not considered as a projectile motion. Gravity, which is absent in a vacuum, is one of the components of projectile motion.

No. "Uniform motion" means motion at a constant speed in a straight line. But the speed of a body falling freely to the ground is continuously increasing, in response to the force of gravity.
Nothing. If the 'weight' of a body is the gravitational force between the body and the Earth, then as long as the body stays at about the same distance from the center of the Earth, its weight is constant, and has no connection with its motion.
motion of free falling object does not have friction, while motion of the cart has force of friction

In the unlikely event you find yourself in a freely-falling elevator, then the relative motion of the pencil is among the least of your concerns.If the pencil were hovering, then both you and the pencil are in free-fall.A condition that is not permanent for you and me, and it will eventually stop.This is commonly referred to as zero gravity, but should be called zero net gravity, for in your space station, gravity still acts - but it is exactly balanced out by centrifugal force. If gravity actually became zero, then your space station would speed off into space.
Freely falling body is a good example
