The nearer the source of sound, the louder is the sound. If the source of sound is far away from the listener, the intensity of sound decreases, by the square of the distance.

Also, the Doppler Effect. The sound of something approaching at speed, such as the horn on a fast-moving railway locomotive, or a police-car siren, is raised in pitch above its true frequency, then drops abruptly to below true as it passes you. This is due to the sound source moving but the sound speed in air remaining constant.
What else can I help you with?
When a force is applied to an object what are the three ways it can change the object?
When a force is applied to an object, it can change the object by accelerating it (changing its velocity), deforming it (changing its shape), or moving it (changing its position).
What is any change in an object's position called?
Any change in an object's position is called motion. This can include moving in a specific direction, changing speed, or changing direction.
Which characteristics of motion could change without changing the velocity of an object?
Some characteristics of motion that could change without changing the velocity of an object include acceleration, direction, and position. For example, an object moving in a circle at a constant speed has a changing acceleration (centripetal acceleration), changing direction, but constant velocity. Similarly, an object can change its position while maintaining a constant velocity if it moves along a straight path.
When can we say that can object is in motion?
An object is said to be in motion when its position is changing over time relative to a reference point. This change in position can be observed through visual cues or measurements of distance traveled.
What is a change in an objects position direction or location?
The change in an objects position is called motion.

How do you when an object is moving?
Change of position relative to another object
When somthing move does it always change in position and direction?
When something is moving or in motion, it can be changing position and direction. However, the object does not have to be doing both at the same time.
What is zero velocity?
An object which is not changing in it's position in space. In simply it is at rest
When can we say that can object is in motion?
An object is said to be in motion when its position is changing over time relative to a reference point. This change in position can be observed through visual cues or measurements of distance traveled.
How does the micros cope change the position of the object being observed?
by changing the position of the object being observed
What is a change in an objects position direction or location?
The change in an objects position is called motion.
What is an object always changing if it is moving in a circle?
If an object is moving in a circle (like a teather ball or a planet in orbit, although orbit is not a perfect circle), then its velocity is always changing (remember that velocity is speed AND direction, and since the direction is changing, the velocity is changing). It's position is also always changing as a result of having a velocity.
Objects in rest and in motion?
An object at rest remains stationary and does not change position. An object in motion is moving from one place to another, typically changing position over time. These concepts are defined by an object's state of movement relative to a reference point.
When an object's distance from another object is changing is what?
When an object's distance from another object is changing, it is in motion. The change in distance indicates that the object is moving relative to the other object.
