The tendency of an object to stay either in constant motion or at rest is known as what?

It is knovn as "inertia". It is mathematicaly explained by the first Newton's law (Law of inertia). Both cases are closely connected to the act of the outer force - in the first case, there hasn't been any force around to make resistance to the object's motion (to change it's direction or to slow it down). In the second case, outer forces have made so big resistance to the object's motion that it has to stop because of the loss of kinetic energy, which has been lost in object's attempt to stay in constant motion.

gravity.\n\nany shape of mass that is not spherical is gravitationally unstable

the body although is one has two velocities one in vertical and other in horizontal direction...the vertical motion is influenced by gravity where as the horizontal is with a constant velocity hence the motion of the body is of two types...const velocity motion, variable velocity motion

Static means it stays in one place and mobile means it moves around i think

A body in motion tends to stay in motion, a body at rest tends to stay at rest. When you grab the first leaf of paper, it is now in motion. The rest of the paper towels are at rest. Now you yank on it. The sheet that is moving wants to keep moving. The roll that is at rest wants to stay at rest. SOMETHING has to give, and since the perferations are the weakest point, it rips there.

That sounds like a "Robert's Rule" question.  Try http://www.robertsrules.com/.  They have a forum specifically for this type question.\n\nMy understanding would be that once a motion carries its permanent unless and until another motion to reverse or suspend was passed.

it is called terminal velocity, at one point no matter the mass, size or shape of an object everything will reach an equilibrium between the gravitational force pulling the object down to earth and the friction the atmosphere causes to slow the fall. If dropped high enough the rate of fall will be constant for any object, the best point to illustrate this is when parashooters all jump at different intervals but all reach a point where they are all falling at the same velocity and time.

when something moves and the weight carries it to keep moving and then it's hard to stop.\n\nLike a freight train or an NFL running back.

Displacement.  If you mean its change in position *divided* by the time it took, that would be its average velocity.

If you're speaking of the motion of Earth on it's axis or it's rotation about the sun, the answer is the scientific principle of Inertia, read now!\n\nThe principle of inertia is one of the fundamental laws of classical physics which are used to describe the motion of matter and how it is affected by applied forces.Inertia is the property of an object to resist changes in velocity unless acted upon by an outside force.Inertia is dependent upon the mass and shape of the object. The concept of inertia is today most commonly defined using Sir Isaac Newton's First Law of Motion, which states:\n\nEvery body perseveres in its state of being at rest or of moving uniformly straight ahead, except insofar as it is compelled to change its state by forces impressed. [Cohen & Whitman 1999 translation]\n\nThe description of inertia presented by Newton's law is still considered the standard for classical physics. However, it has also been refined and expanded over time to reflect developments in understanding of relativity and quantum physics which have led to somewhat different (and more mathematical) interpretations in some of those fields.\n\nNow read more at the links below:

hmmm, good question....\n\nMaybe because it seems to be in a constant state of falling.

Oscillation is a periodic movement which involves to and fro motion, when u suspend a particle or object from a certain height.\nFor ex.- Movement of pendulumn\n\nVibration is also a periodic movement that takes place vigorously at fixed position(either up and down or sideways).For ex.-when u beat a steel plate forcefully, u observe the movement in plate, ththat is vibration. And best of luck for ur classes and enjoy studies especially science.

No force is needed to maintain motion.  You need a force to change motion: speed up, slow down, or change direction.

it means the object is not moving, as the distance remains constant

More information needed:\nStanding, sitting, or lying?\nWeight?  Height?  \nDistance between the feet ("stretched wide apart")?\n\nBasically, an object is stable if the center of mass is over the base.  Stability increases with the size of the base and the lowering of the center of mass; i.e., decreasing the ratio of CM height:base.\n\nHope that helps.

center of gravity \n\nThe point in any solid where a single applied force could support it; the point where the mass of the object is equally balanced. The center of gravity is also called the center of mass. When a man on a ladder leans sideways so far that his center of gravity is no longer over his feet, he begins to fall.

Inertia\n\nOne of Newton's Laws - Objects in Motion tend to remain in motion unless acted upon by an outside force such as gravity.
