You add the velocity of the other frame of reference, to the object's velocity compared to that frame of reference. Example: a train moves at 60 km/h; a man in the train walks forward at 5 km/h (that is with respect to the train). Adding the two speeds gives 65 km/h. If the movements are in different directions, vector additions is needed. Basically you can add x, y, and z-components of the velocities separately. The above assumes the speeds are non-relativistic; otherwise a different and more complicated formula is required.
If an object is at rest, it has no velocity - its velocity is zero. More precisely, since velocity is a vector, in this case the velocity would be the null vector.
at rest means not moving, that is, velocity is zero
Rest.
Rest. At rest denotes a constant velocity including velocity of zero. Newton's Law says that a body will change its velocity ,accelerate or decelerate, only when an external force is applied. No force, no acceleration, no change in velocity. At rest itself denotes no force.
Yes.
Velocity can only be measured in relation to some specified point of rest, so there is no such thing as absolute velocity. All velocity is relative.
Momentum is defined as the product of the mass and the velocity. P = mv. As the body is at rest its velocity v = 0. Hence momentum P =0.
No. Velocity means speed.
An object at rest has a velocity of zero.
Zero.
The momentum of a body is defined as the product of is mas and velocity. Momentum = Mass x Velocity. If a body is at rest then obviously its velocity is zero. Therefore, its momentum also becomes zero.
you are still. motion is at rest.

"stopped" or "at rest"
Momentum is defined as the product of the mass and the velocity. P = mv. As the body is at rest its velocity v = 0. Hence momentum P =0.
Any object which is at rest has zero velocity, for example a rock on the road. car parked at lane, a motor which is not moving or stop. a man sleeping. home office statue of liberty. anything that is at rest has zero velocity.
