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.

The v is the same as the ending velocity when the object starts from?
Rest.
A body at rest tends to stay at?
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.
Is zero the velocity of an object at rest?
Yes.
What is the definition of absolute velocity?
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.
How do you find momentum 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.
Is there velocity when the object is at rest?
No. Velocity means speed.
What is an object at rest has its velocitty?
An object at rest has a velocity of zero.
What is the velocity of a boady if it is at rest?
Zero.
If you are at rest do you have momentum?
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.
When average velocity is equal to its instantaneous velocity acceleration?
you are still. motion is at rest.
The v is the same as the ending velocity when the object starts from?
Rest.
