Why does an observer use a frame of reference to detect motion?
An observer uses a frame of reference to detect motion because motion is relative and depends on the observer's point of view. By using a frame of reference, the observer can establish a stationary point against which to measure an object's position and velocity. This helps in determining whether an object is in motion or at rest relative to the observer.
How the apparent motion of a object depend on the observer motion?
The apparent motion of an object can vary depending on the motion of the observer. This is due to the concept of relative motion, where the perception of an object's movement is influenced by the observer's own motion. For example, if the observer is moving towards an object, the object may appear to move faster than if the observer is stationary.
Is motion always observed from some stationary or relative position?
Motion is always relative to something. There's no such thing as really "stationary."Stationary only means that the motion of the observed object matches the observer's motion. Example: Reading the book that lies 'stationary' in your lap while you're in a car or on a passenger jet.
How does apparent motion of an object depend on the observer and in motion?
The apparent motion of an object depends on both the observer's perspective and the motion of the object itself. As the observer moves, their angle of view and distance from the object change, altering how the object appears to move relative to them. In addition, the speed and direction of the object's actual motion will impact how it appears to move to the observer.
Are motion and rest absolute or relative?
Motion and rest are relative concepts, as they depend on the frame of reference from which they are observed. An object in motion appears differently depending on the frame of reference from which it is observed, so motion and rest are not absolute but rather determined by the observer's perspective.

Motion relative to observers frame of?
Motion is relative to an observer's frame of Reference.

An object in motion appears differently depending on the frame of reference from which it is observed, so motion and rest are not absolute but rather determined by the observer's perspective.
Why does observer measure waves from an approaching source as having a higher frequency than if the source were standing?
This is due to the Doppler effect, where the motion of the source compresses the waves as it approaches the observer. This compression increases the frequency perceived by the observer. If the source were stationary, there would be no relative motion and no frequency shift.
What must motion be measured relative to?
Motion must be measured relative to a frame of reference, which is a set of coordinates that are used to determine the position of an object in space. This can be a stationary object, another moving object, or an observer. The motion of an object is described in terms of its change in position relative to the chosen frame of reference.
What is a phenomenon that depends on the relative motion of the source and the observer?
The Doppler effect is a phenomenon that depends on the relative motion of the source and the observer. It is the change in frequency or wavelength of a wave in relation to an observer moving relative to the source of the wave.
Why motion is a relative term?
Motion is relative because it is always defined relative to a reference point or frame of reference. An object's motion may appear different depending on the observer's perspective or frame of reference, making it a relative term. This is described by the concept of relative motion in physics.
Can the motion of an object change depending on the frame of reference?
It depends on inertia.
What is a rest relative to a seated passenger in a moving car?
A rest relative to a seated passenger in a moving car refers to the state of being stationary compared to the passenger's frame of reference. While the car is in motion, the passenger perceives themselves and any objects inside the car as being at rest, even though the car is moving at a certain speed relative to the outside environment. This concept highlights how motion is relative and depends on the observer's perspective.
