Speed is always the speed relative to something else.
If you see something standing still, that just means that it's moving
with exactly the same speed and direction that you are. The object that's
standing still could be the book in your lap in a seat on a passenger jet
flying at 500 miles per hour, relative to the ground, to visit your grandmother.
And don't forget that the airplane, you, and the book, are all spinning along
with the Earth, while the Earth and all of those things revolve around the sun.
There's no such thing as really standing still.
They are the exact same. If an object is standing still, it is in motion. Everything in the world is in motion. Not because of the earth moving, it is because particles in all objects are moving.
When an object is still it has no momentum. That is, the momentum is zero.
When an object is standing still, its velocity, acceleration, and net force are always zero.
If there are any forces acting on a stationary object, then they must be balanced, or it would no longer remain stationary.It is also possible that the object is already moving. In the forces are balanced on a moving object, the object would continue moving at the same speed and direction (velocity) that it already had.
When an object is standing still, the velocity of the object is zero, as it is not moving in any direction. Additionally, the kinetic energy of the object is zero, as there is no motion to produce energy. Lastly, the acceleration of the object would also be zero if it remains at rest.
Its speed, velocity, and acceleration are all zero.

Velocity. When an object is standing still at position p, the velocity dp/dt = 0 is zero.

In the forces are balanced on a moving object, the object would continue moving at the same speed and direction (velocity) that it already had.
I suppose the forces may crush the object, but they won't move it.
No. If the horizontal axis is time, and the vertical axis is speed, and you're standing still,Then the graph is perfectly horizontal, and it coincides with the horizontal axis.
They may crush it, but they won't move it.
It is the speed of neutrinos. Why they are faster than the speed of light? Ckeck results of recent LHC experiments.
When an object is standing still, the velocity of the object is zero, as it is not moving in any direction. Additionally, the kinetic energy of the object is zero, as there is no motion to produce energy. Lastly, the acceleration of the object would also be zero if it remains at rest.
An object can accelerate while still traveling at a constant speed if it changes direction. Acceleration is the rate of change of velocity, so even if the speed remains constant, a change in direction would still require acceleration.
