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.
See what I mean ?

What 3 thing do you need to know to determine velocity?
To determine velocity, you need to know the object's speed (how fast it is moving), the direction in which it is moving (velocity is a vector quantity with magnitude and direction), and the reference point or frame of reference from which the velocity is being measured.
What do you need to know for velocity?
To determine an object's velocity, you typically need to know its speed and direction of motion. Velocity is a vector quantity, so it has both magnitude (speed) and direction. Additionally, knowing the frame of reference is important for calculating velocity accurately.
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.
What is the difference between inertial reference frame and absolute reference frame?
An inertial reference frame is a frame of reference in which an object not subject to external forces moves at a constant velocity. An absolute reference frame is a hypothetical frame of reference that is fixed in space and in which all other frames of reference are measured. Inertial reference frames are relative to each other, while the absolute reference frame provides a universal standard of motion.
Why can velocity be zero?
Velocity can be zero if an object is at rest or not moving. This means that the object's speed and direction are not changing over time. In other words, the velocity of an object is zero when there is no movement or change in its position.

What is happening to an object when it has an 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
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.
How does the velocity of an object change when observed from a moving frame of reference?
When an object is observed from a moving frame of reference, its velocity may appear different due to the relative motion between the observer and the object. This change in velocity is known as relative velocity, and it can be calculated by considering the velocities of both the object and the observer.
Is the inertial reference frame an absolute reference frame?
No, an inertial reference frame is not an absolute reference frame. It is a frame of reference in which an object either remains at rest or moves with constant velocity in a straight line, but it is not considered absolute as its motion can be affected by external forces.
What happen 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
What is the most common frame of reference?
The most common frame of reference in physics is the inertial frame of reference, where an object is considered to be at rest or moving with constant velocity. Observers in different inertial frames will agree on the laws of physics governing the motion of objects.
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.
