No object that has mass when it's just sitting there on the table can move at the speed of light.

Photons have zero "rest mass".

Can any object move with the velocity comparable to the velocity of light?

Recently an experiment at the CERN has clocked a Neutrino that they believe EXCEEDED the speed of light. They are double checking the results of this experiment, and looking for explanations.


How fast an object move?

The maximum speed of any object is hardly equal to speed of light which is 3*10^8 approximately.


What is the effect of gravity on velocity?

Gravity affects velocity by changing the acceleration of an object. As an object falls, gravity accelerates it, increasing its velocity. Without gravity, an object would move at a constant velocity.


What describes how fast an object is moving and in what dirrection?

The maximum speed of any object is hardly equal to speed of light which is 3*10^8 approximately.


When an object move are the force acting on it?

Not necessarily. An object doesn't need a force to move, only to CHANGE its velocity. In empty space, an object can continue moving indefinitely without any force.


If you know the constant velocity of a moving object what can you predict?

If you know the constant velocity of a moving object, you can predict its position at any future time by multiplying the velocity by the time elapsed. This assumes that the object continues to move at that constant velocity without any external forces acting on it.


Is it possible that body is moving with constant velocity but force acting on it is zero?

Yes, in fact, it is necessary. If any net force acts on an object, the velocity will change.Yes, in fact, it is necessary.

Which would take less force to move a heavy object or a light weight object?

When you include the effects of friction, it takes less force to move a light-weight object. If you can get the objects into a frictionless environment, then any force, no matter how small, can move any object, no matter how heavy.


How an object could still be moving with the 0 acceleration?

An object can still be moving with zero acceleration if it is moving at a constant velocity. When acceleration is zero, the object's velocity remains constant, meaning it continues to move at the same speed and in the same direction without any change in speed or direction.


The greatest velocity that an object reaches?

It has been proven that the speed of light (about 3 x 108 meters per second) is the maximum speed any object can reach.


Momentum of an object depends on it's what and what?

Velocity. It is the product of the two quantities.


Can an object be accelerating if it has a constant velocity?

No. The definition of 'acceleratiion' is 'any change in velocity'.
