A change in the pitch of the horn, rising as the train approaches and falling as it recedes.
The elevator is accelerating downwards.
a car become positively active when we can notice that there is an acceleration.
Simply, no. Molecules will stop moving when the temperature of the substance reaches its "freezing" point, eg., 0C for water or -40C for mercury.
That could be one description of "force" or "net force."Notice that it can also change the direction in which an object is moving,without changing its speed at all.
The high pitch start would do so later and be higher pitch until the passing of the two moving objects where the low pitch would be lower and end sooner. basically,yes.
We don't notice because the move so slowly. Even the fastest-moving plates are moving at only about 3 inches per year.
i notice friction when a moving object is being stopped by a living object
you don't notice the earth moving because everything else moves along with the earth as it moves.
most loaland ask for a 30 day notice
We are moving with it, at the same speed, which means we can't feel or notice it in any ways.Everything else moves aswell, so we can't see that we are moving, when comparing to towers, trees, etc.
When stars or galaxies are moving away from the observer, you will notice a redder shift in the color of the body.
with confidence and standing out :)

The Doppler effect occurs whether the sound source or the listener is moving. You wont notice the Doppler effect on a slow moving train because the radio wave is reflected, its frequency changes depending on the speed of the object.
You are moving with it. =================== Think of it this way. You are in a mary-go-round...... Do you see the ride moving or the people standing outside the ride moving. You can see the earth revolving by tracking the position of the stars. At a particular time of the night take a polythene and tell your buddies to hold it up. Mark some of the stars in its place on the polythene by looking through it. After a few days do the same and you would notice the difference in their relative positions.
Many leases simply automatically renew if you do nothing at the end of the lease period. Others will send you a notice with a date by which you must reply. You will be charged a fee if you do not provide 30 days notice, but it is usually pro-rated.
