Can anyone give definition for Doppler frequency?
It is not Doppler frequency. It's Doppler effect. The APPARENT change in the frequency of the source as there is a relative motion between the source and the observer is defined as Doppler effect. The expression for frequency (apparent) is given fapparent = [(C - Vo + Vm)/(C-Vs+Vm)] x freal The condition to be kept in mind is that the source is on the left side and the observer on the right side along positive X axis. Vm - velocity of the medium and the medium is moving along positive X axis. Vo - the velocity of the observer Vs - the velocity of the source C - velocity of the wave either sound or light But in case of light Vm is not needed as the medium movement will not affect the velocity of the wave in any way.
What is the difference between linear motion and random motion?
Linear Motion is motion of object/body along a straight line.Random Motion is the motion of an object/body along a disordered or irregular line.
What are the 3 types of motion and there definition?
( 1 ) rectilinear motion which is motion along a straight line( 2 ) curvilinear motion which is motion along a curve or in a circle( 3 ) oscillatory motion which is motion back and forth
Why is the motion of an athlete moving along the circular path an accerlated motion?
Because 'accelerated motion' means any change in speed orany change in directionaway from a straight line. So motion on a circular path is always accelerated motion.
What is 1 dimensional motion?
It is motion that is confined a single direction. That being said you can also expand it to include motion along a single line such as when a bead moves along a curved wire.

What does motion sensor detect?
There are a few different ones out there, but most of them work by the Doppler principle and on sound at ultrasonic frequencies. Doppler effect is the appearent shift in the frequency of a signal (wave) because of motion of the source or observer (or both) toward or away from each other. We've seen Doppler effect in action. Like with a train or race car. As the vehicle comes toward the observer, we hear a sound. As the vehicle zips by, the pitch or frequency of the sound drops. That's Doppler effect. By installing a small ultrasonic sound transmitter and receiver, an area of coverage is "painted" with the ultrasonic sound. Then the receiver along side it listens for an echo. If nothing in the room is moving toward or away from the source, all the returning signals will be the same as the ones that left the source. But if there is some relative motion, the detector "hears" the difference in the pitch of the sound (Doppler effect) and an alarm is triggered.
Why the Doppler shift tells us only about the motion directly along the line of sight between a light source and an observer but not about motion across the celestial sphere?
A lateral (sideways) movement doesn't change the frequency, because in this case, the distance between the object and the observer isn't changing.

What is circulatory motion?
It is the motion along a circular path.
What is curvillinear motion?
Curvilinear motion is the motion of an object in a curved path rather than a straight line. It involves changes in both speed and direction as the object moves along the curve. Examples of curvilinear motion include circular motion, parabolic motion, and elliptical motion.
What is rectilinear motion?
The motion along a straight line is known as rectilinear motion.
How does gravity effect motion?
Gravity is completely responsible for planetary motion. The shape and size of each orbit, and the speed of the planet at every point in its orbit, taken along with the mass of the sun, are completely determined by the behavior of gravity.
Is uniform circular motion is accelerated motion?
if an object moves along a circular path, the only change in its velocity is due to the change in the direction of the motion. The motion of the object moving along the circular path is, which is a uniform circular motion, is therefore an accelerated motion:):):):/
Why uniform circular motion is called accelerated motion?
if an object moves along a circular path, the only change in its velocity is due to the change in the direction of the motion. The motion of the object moving along the circular path is, which is a uniform circular motion, is therefore an accelerated motion:):):):/
Why is the motion of an athlete moving along the circular path an accerlated motion?
Because 'accelerated motion' means any change in speed orany change in directionaway from a straight line. So motion on a circular path is always accelerated motion.
