What is a apparent change in pitch of a sound caused by the motion of the object making the sound?
This is an example of the Doppler effect.
Sound is composed of waves.
A particular vibration produces a sound wave with a particular wavelength.
When the sound source moves towards a listener the waves are "bunched up". That results in a shorter observed wavelength and thus a higher frequency.
When the sound source moves away the opposite happens. The frequency of the sound waves decreases.

What is the apparent change in the freqency of a sound caused by the motion of either the listener o the source of sound?
The apparent change in frequency of a sound caused by the motion of either the listener or the source of sound is known as the Doppler effect. If the source is moving towards the listener, the frequency appears higher (higher pitch), and if the source is moving away, the frequency appears lower (lower pitch).
What is the scientific term for the apparent curved motion of moving objects called?
The scientific term for the apparent curved motion of moving objects is called "Coriolis effect." It is caused by the rotation of the Earth and can affect the paths of objects moving across its surface.
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.
What is A change in an object's state of motion is caused by?
A change in an object's state of motion is caused by the application of an external force acting on the object. This force can be in the form of a push, pull, or any other interaction that changes the object's speed or direction of motion.
What is any change in motion caused by?
force! (i think) It was in my science book... so that is what i am assuming!It is actually an unbalanced force not just a force. -Kelsey Munroe

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.
What caused change in motion of an object?
Force.
What is the line that the sun traces across the celestial sphere?
The "ecliptic". In truth, the Sun doesn't move; the apparent motion of the Sun across the sky is caused by the Earth spinning, and the apparent motion of the Sun across the "celestial sphere" is caused by the Earth orbiting the Sun. But the plane of the Earth's orbit around the Sun is what causes the apparent motion of the Sun across the celestial sphere, so the "ecliptic" is actually the plane of the Earth's orbit.
The apparent westward movement of a planet is known as?
The apparent westward movement of a planet is known as retrograde motion. This phenomenon occurs when a superior planet passes Earth in its orbit, making it appear to move backward in the sky relative to the stars.
Any change in motion is caused by?
Energy applied to it.
What is apparent change in pitch of a sound caused by the motion of the object making the sound?
this is the Doppler effect where sound waves are compressed in front of a moving object and exapnded behind it. Thus the pitch appears higher as an object approaches than when it receeds. At just below Mach 1, the sound wave is compressed to twice the frequency so the Doppler shift would be almost 2 octaves (factor of 4 between compresson and expansion) as the object passed.
Why there are seasons and the apparent motion of the stars and sun?
Seasons are caused by the tilt of Earth's axis as it orbits the Sun, which creates variations in temperature and daylight. The apparent motion of the stars and the Sun is due to Earth's rotation on its axis, giving the illusion that these objects move across the sky.
