no when the body the body is in motion only
Yes, gravity is constantly acting on all objects even when they are at rest.
Yes, it all depends on the point of view. An object can be at rest for one observer, and in uniform motion for a different observer.
Newtons laws of motion
no its not possible. if there is only one force acting on an object.
The centre of gravity does not, by itself, determine whether an object is at rest or in motion. The location of the centre of gravity, relative to where the object is supported, can contribute one of many forces that can act on the object. And it is is the [vector] sum of these forces which determines whether the object remains at rest or in uniform motion.
The object will remain at rest if it was at rest or will maintain its motion with uniform velocity if it was moving.
Isaac Newton's first law of motion says that an object at rest tends to remain at rest. Newton's second law says that an object in motion tends to remain at motion in a uniform velocity unless acted upon by an outside force. Together, these are "inertia"; the tendency of stopped objects to stay stopped, and of moving objects to continue movement.
The object remains at rest or in uniform motion.
yes
