A body is said to be in motion when it changes its position with respect to its immediate sorroundings and it is at rest when it does no changes its position with respect to its sorroundings (immediate).

What is a body that is not moving is said to be at what?
At rest.
Can a body have acceleration while at rest?
yes!A2. The real problem is deciding when a body is at rest - or is it just the rest of the universe that is moving?
How are a body at rest and body moving similar in velocity?
A body at rest and a body in motion have completely different velocities.Magnitude of velocity:At rest . . . zeroMoving . . . not zeroDirection of velocity:At rest . . . no directionMoving . . . some direction
What is at rest relative to a seated passsenger in a moving car?
Everything else in the car that is not itself rotating etc. is at rest relative to the passenger -- the seats, car body, dashboard, windows, etc, "At rest" is in this case just another way to say "moving at the same velocity."
Will a body remain at rest if no net force acts on it?
If it was initially at rest - yes. If it was initially moving, it will continue moving at the same velocity.
What is a body that is not moving is said to be at what?
At rest.
What is a body that is not moving is said to be at?
At rest.
What is absolute rest and absolute motion?
motion : when a body is moving or changing its position with respect to its surroundings is called motion. rest: when a body is not moving or fixed at a place with respect to its surroundings is called rest.

If it was initially at rest - yes. If it was initially moving, it will continue moving at the same velocity.
What is static inertia?
Static inertia is when a body at rest wants to stay at rest, or a body that is moving at a constant speed stays at the constant speed.
Sketch a distance time graph as when a body is at rest and when a body is moving with constant speed?
about a hour
What does it mean to say something is in mechanical equilibrium?
It means there are no unbalanced forces, or the net force is zero. That means if a t rest it will stay at rest, or if in motion it will stay in motion with no acceleration.It means that there is no net force acting on the object(s). A body moving at constant velocity is in mechanical equilibrium. A body that is not moving is in static equilibrium.
Can a body at rest said to be in motion?
Any body in the universe is never said to be rest as the electrons inside it keeps moving to and fro and thus no matter on the universe is in standard rest.
When do we say that a body is in motion?
That means that it is moving.
