How are inertia and motion related?
Inertia is an object's resistance to change it's state of motion or rest. Motion or rest depends on the observer's frame of reference.
The apparent change in the frequency of a sound emitted by a moving object as it passes a stationary observer is called the what effect?
Doppler effect.
How is the size of an object affected by its distance from an observer?
Its size is not affected in the least by its distance from an observer. If it were, can you possibly imagine thestress and strain on Brett Favre's body during a game, as he is watched by 60,000 people in the stands, allat different distances from him ? ! ?The object's APPARENT size ... i.e. the angle that it subtends at the eye of the observer ... depends onthe observer's distance from it, in the following totally predictable and purely geometrical fashion:The angle subtended by the object =arctangent [ (object's dimension perpendicular to the line of sight) divided by (observer's distance) ].But that's the observer's fault, not the object's.
How far an object travels in a certain period of time is?
Relative or apparent motion.
What do motion depend on?
There are three things that motion depends upon. The first is the mass of the object that is to be set into motion. The second is the strength of the friction that is going up against the object. The third is the strength of the gravity that is pulling upon the object.
What is a parallax error?
Parallax, more accurately motion parallax, is the change of angular position of two observations of a single object relative to each other as seen by an observer, caused by the motion of the observer. Simply put, it is the apparent shift of an object against a fixed background that is caused by a change in the observer's position.
How does apparent force affect the motion of an object?
Accelerates the motion of an object.
An object is in motion if it changes position relative t a?
Observer.
What is earths apparent motion?
I guess that would be an earthquake. But what do I know. I think it is though.
Can a body be said to be in rest or in uniform motion in same time?
Yes, it all depends on the point of view. An object can be at rest for one observer, and in uniform motion for a different observer.

Inertia is an object's resistance to change it's state of motion or rest. Motion or rest depends on the observer's frame of reference.
The apparent change in the frequency of a sound emitted by a moving object as it passes a stationary observer is called the what effect?
Doppler effect.
The energy of an object in motion will depend on what?
Its velocity and its mass.
What creates the phenomeon known as red shift?
Two things can cause red-shift:- The rapid motion of an object away from the observer. This is known as the Doppler-effect.- Expansion of space between the object and the observer.

Does the path of an object's projectile motion depend on the angle?
yes
