Frame of reference is related to motion because reference points enable us to see that an object is moving.
========================
Motion is related to a frame of reference because there is no such thing as 'real' motion
or 'real' rest. 'Rest' and 'motion' are always with reference to something else.
The book that you are reading is at rest with reference to your lap, your lap is at rest
with reference to the seat you're sitting in, and you, the book, and the seat are all at
rest with reference to the airplane you're flying in at 400 miles per hour.

What does the velocity of car A which is traveling at 50 ms West appear to be from your frame of reference?
Depends entirely on your frame of reference! If you are in a car traveling along side it at 50 ms, the car will appear to be standing still. If you are going the opposite direction at 50 ms, it will appear to be traveling at 100ms.
Why can velocity be zero?
Something may be completely stationary relative to its frame of reference.
Speed and direction of motion?
the speed of motion is determined by how fast the object in motion is traveling along with the distance it has traveled. the direction of motion can be discovered by either using a frame of reference (point of comparison) or simple devices such as a compass.
What is happening to an object when it has positive acceleration?
Either of these is referred to as positive acceleration: A) the object's velocity is increasing in the frame of reference B) the object is being moved in a positive direction in a coordinate plane
Why earth is inertial frame of reference?
because it is non.accelerated as it as a uniform velocity of revlving around sun.

How can measurements made with one frame of reference be translated to the measurements made using another frame of reference?
You would add the characteristics of the original reference frame itself. For example, if you know the walking speed of a man on a bus with respect to the bus and you want to know the velocity of the man with respect to the ground, find the vector sum of the man's velocity w.r.t. the bus and the bus' velocity w.r.t. the ground. If one reference frame is not a subset of the other, solve first for a reference frame they have in common. For example, if you want to know the velocity of the man in the first example with respect to a passing truck, find his velocity with respect to the ground first. Keep in mind that "forward" can mean different directions in different reference frames.

Is air travel energy requirements the same whether or not the plane is flying with or against the rotation of the earth?
That should be the same; what matters to the plane is the velocity in relation to the air, not in relation to some frame of reference outside the Earth.That should be the same; what matters to the plane is the velocity in relation to the air, not in relation to some frame of reference outside the Earth.That should be the same; what matters to the plane is the velocity in relation to the air, not in relation to some frame of reference outside the Earth.That should be the same; what matters to the plane is the velocity in relation to the air, not in relation to some frame of reference outside the Earth.
Why is velocity a vector quantity?
Velocity refers to both speed and direction. A vector refers to both magnitude (the speed in this case) and a direction. Speed without reference to a direction is a scalar, a magnitude without direction.
Speed what does it mean?
Speed is the relative velocity of a body (such as an athlete) given a frame of reference (such as the ground).
Why earth is inertial frame of reference?
because it is non.accelerated as it as a uniform velocity of revlving around sun.
What is the physical meaning of a negative average velocity?
It means that an object with a negative average velocity is moving in the opposite direction (of course according to the chosen positive direction of the predefined frame).
