Solution : In a uniform circular motion (UCM), a particle takes the same time to complete each revolution, a distance equal to the circumference of the circle. Therefore, a UCM is called a periodic motion.
When can we say that circular motion is periodic?
Circular Motion can be an example of periodic motion, if motion in a circle is repeated in equal intervals of time.
What is meant by period of revolution of UCM?
The time taken by a particle performing uniform circular motion to complete one revolution is called as period of revolution. It is denoted by T and is given by, T = 2π/ω. Unit: second in SI system.
Is all circular motion is periodic motion?
All circular motions are periodic motions. All circular motions are periodic motions.
Why is circular motion not periodic?
circular motion is when it is moving in circular track. periodic motion is when it is repeating its track after interval of time. So when circular motion is repeated, it also becomes periodic motion. best example will be hand of clock… they make circular motion as well as they repeat after interval of time.
What is periodic motion?
periodic motion, in physics, motion repeated in equal intervals of time. Periodic motion is performed, for example, by a rocking chair, a bouncing ball, a vibrating tuning fork, a swing in motion, the Earth in its orbit around the Sun, and a water wave.
What is time period in UCM write SI unit of its?
In circular motion time taken by object to complete one revolution on its circular path is called its time period.SI units is sec. Frequency is number of revolutions by object is unit time. SI unit is Hertz.
What is the period of revolution of a particle performing UCM and state it is expression and SI unit?
The period is the time required for the object to complete one revolution of motion. The angular speed is the angular displacement per second and it is related to the frequency by: ω=2πf with ω in rad/s.
What is uniform circular motion?
Uniform circular motion is a specific type of motion in which an object travels in a circle with a constant speed. For example, any point on a propeller spinning at a constant rate is executing uniform circular motion. Other examples are the second, minute, and hour hands of a watch.
How periodic motion is differs with circular motion?
Circular motion is where the object travels in a path which is circular -can be a full circle, can be a part of the circle. Periodic motion is where the object repeats its motion after a particular time. Therefore when an object isuniformly moving in a circle and it completes360 degrees, it repeats itself.
How is periodic motion different from circular motion?
The motion of an object in a circular path is called circular motion. The motion of an object which repeats itself after a certain period of time is called periodic motion.
What is the difference between rotational and periodic motion?
When an object moves about an axis and different parts of it move by unequal distances in a given interval of time, it is said to be in rotational motion. Example: Motion of blades of a windmill. A motion that repeats itself after equal intervals of time is called periodic motion.
Is circular motion periodic or oscillatory?
periodic
Thus, circular motion is only periodic and not oscillatory because the wheels do not move to and fro about a mean position.
Why the circular motion of a particle with constant speed is periodic but not simple harmonic?
In circular motion of a particle with constant speed, particle repeats its motion after a regular interval of time but does not oscillate about a fixed point. So, motion of particle is periodic but not simple harmonic.
Is constant speed periodic motion?
The circular motion of a particle with constant speed is uniform circular motion. Due to constant speed, the object will cover equal distances in equal intervals of time. Hence, the circular motion will be repeated in equal intervals of time. So, it is a periodic motion.
What is periodic motion class 9?
A motion that repeats itself after equal intervals of time is known as periodic motion.
What is periodic motion class 11?
Periodic Motion refers to those motions where the object repeats its motion after a certain period in time. This motion is described by parameters such as angular frequency and angular speed. The least time after which the motion is repeated is referred to as Time period of the motion.
What is periodic motion class 7th?
Periodic motion is a motion that repeats in equal intervals of time.
How are periods calculated UCM?
The distance around a circle is equivalent to a circumference and calculated as 2•pi•R where R is the radius. The time for one revolution around the circle is referred to as the period and denoted by the symbol T. Thus the average speed of an object in circular motion is given by the expression 2•pi•R / T.
What is Omega UCM?
How can counterclockwise be a direction? The same letter ω is often used to the represent the angular speed, which is the magnitude of the angular velocity. Velocity v measures the amount of displacement per time.
Which of the following is zero in UCM?
(1) In uniform circular motion, tangential acceleration is zero.
