What is the difference between periodic motion oscillatory motion and simple harmonic motion?

A motion that repeats itself again and again at regular intervals of time is called a periodic motion. All oscillatory motions are periodic motions but all periodic motions are not oscillatory. Simple harmonic motion is a straight line motion and it requires a restoring force.

What is the difference between simple harmonic motion and simple harmonic oscillation?

A simple harmonic motion requires a restoring force. The restoring force can be a spring, gravitational force, magnetic force, or an electric force. A simple harmonic oscillation will not emit any energy. The total mechanical energy of the system is conserved.

What is the difference between oscillatory and vibratory motion?

Note: A type of motion in which a particle vibrates about a fixed point is called vibratory motion. A type of motion in which a particle moves to and fro about a fixed point is called oscillatory motion.

What is the difference between damped oscillation and forced oscillation?

Damping is the reduction in amplitude (energy loss from the system) due to overcomings of external forces like friction or air resistance and other resistive forces. When a body oscillates by being influenced by an external periodic force, it is called forced oscillation.

What are damped oscillations?

A damped oscillation means an oscillation that fades away with time. Examples include a swinging pendulum, a weight on a spring, and also a resistor – inductor – capacitor (RLC) circuit. We can use these equations to discover when the energy fades out smoothly (over-damped) or rings (under-damped).

What is difference between frequency and oscillation?

Frequency of a wave simply refers to the number of complete cycles or oscillations that occur in one second. It is measured in cycles per second or hertz (Hz). A cycle is one complete oscillation and a vibration can be a single or multiple events, whereas oscillations are mostly repetitive for a number of cycles.

What is the difference between oscillatory and rotational motion?

Rotational motion is when something is moving in a circle – like if I took a ball on a string and swung it around my head. Oscillating motion is when something is going back and forth and back and forth.

What is the difference between the natural frequency and the damped frequency of oscillation?

When an undriven, undamped oscillator is displaced from equilibrium, the system will oscillate at its natural frequency. The damped oscillation frequency does not equal the natural frequency. Damping causes the frequency of the damped oscillation to be slightly less than the natural frequency.

What is the difference between simple harmonic motion 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. Any type of repeated motion requires a force.

What are simple harmonic oscillations?

The harmonic oscillations of constant amplitude and a single frequency is known as Simple Harmonic Oscillations. A body is said to be executing a simple harmonic motion if its acceleration is directly proportional to the displacement from the mean position at any instant and it is always directed towards the mean position.

What is an oscillation in physics?

Oscillations are a type of periodic motion. An oscillation is usually defined as a repetitive variation over time. The oscillation can occur over a middle equilibrium point or between two states. A pendulum is a good example for an oscillatory motion.

Why is SHM not a repeating or periodic motion?

Because if there is no force acting against the SHM, it will not subject to a damping (damping motion is not SHM). So, it is a repeating or periodic motion. But the inverse of this is not always true. So, there can be periodic motions that are not simple harmonic (circular motion is periodic but not simple harmonic).
