### Why all periodic motions are not SHM?

Earth repeats it's motion after fixed interval so we call it periodic motionbut there is no restoring force so we can't call it s.h.m. If **a particle moves such that it repeats its path regularly after equal intervals of time** , it'smotion is said to be periodic.

### Which motion is not simple harmonic motion?

The motion of a planet around the sun is **a periodic motion** but not a simple harmonic motion. All other given motions are the examples of simple harmonic motion.

### Is all periodic motions are oscillatory?

Answer: **All oscillatory motions are periodic** because each oscillations gets completed in a definite interval of time. Eg: On being pulled and then released, a load attached to a spring executes oscillatory motion. On the other hand, all periodic motions may not be oscillatory.

### What is the difference between periodic motion and SHM?

The main difference between simple harmonic motion and periodic motion is that **periodic motion refers to any type of repeated motion** whereas simple harmonic motion (SHM) refers to a specific type of periodic motion where the restoring force is proportional to the displacement. ...

### What is periodic motion example?

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. ... Waves that can be represented by sine curves are periodic.

### What is the example of non-periodic motion?

Examples of non-periodic motion: **Motion of tides in the ocean**. **The running of a batsman between the wickets**. **Flowing of water into the streets during floods**. **Motion of birds flying in the sky**.

### Can oscillatory be non periodic?

Every oscillatory motion is periodic, but **every periodic motion need not be oscillatory**. Circular motion is a periodic motion, but it is not oscillatory. ... This motion arises when the force on the oscillating body is directly proportional to its displacement from the mean position, which is also the equilibrium position.

### What is the difference between SHM and periodic motion?

The main difference between simple harmonic motion and periodic motion is that **periodic motion refers to any type of repeated motion** whereas simple harmonic motion (SHM) refers to a specific type of periodic motion where the restoring force is proportional to the displacement.

### Why is SHM rare?

Answer and Explanation: Simple harmonic motion is rare **because in nature the frictional forces are not negligible and bodies that move in an oscillatory manner decrease their amplitude in their interaction with the air that surrounds them**. Simple harmonic movement is characterized by having a constant amplitude.

### What is periodic motion Give 5 examples?

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.

### Which is a special case of periodic motion?

Periodic motion refers to any type of repeated motion. In this sense, simple harmonic motion is also a special case of periodic motion. That is, any simple harmonic motion (SHM) is periodic.

### Is the simple harmonic motion always oscillatory?

The periodic motion may or may not be oscillatory. Simple harmonic motion is always oscillatory. Learn the difference between Periodic and Oscillatory Motion here. A is true and R is false. A is false and R is true. Solution: c) A is true and R is false. V = ω√A 2 – x 2 is measured from the mean position. SHM involves to and fro periodic motion.

### Is the frequency of a harmonic motion a periodic function?

They are periodic functions encapsulated in other periodic functions. The inverse of the frequency of the periodic motion gives the time for a period. Simple harmonic motions and damped harmonic motions are also periodic motions.

### Is the pendulum in periodic motion or simple harmonic motion?

A simple pendulum oscillating through a small angle is also in simple harmonic motion. If the pendulum has a length , the period of its simple harmonic motion is given by: where is the acceleration due to gravity. A pendulum in a grandfather clock undergoes simple harmonic motion. Periodic motion refers to any type of repeated motion.
