Mean Position or Equilibrium Position : It is a position of the body when the net force acting on it is zero. Phase of a particle in oscillatory motion :This represents the state of vibration of the particle at a given time.
What is oscillatory motion and time period?
This fixed interval of time is known as time period of the periodic motion. Examples of periodic motion are motion of hands of the clock, motion of planets around the sun etc. Oscillatory motion is defined as the to and fro motion of the body about its fixed position. Oscillatory motion is a type of periodic motion.
What is the equilibrium position in oscillatory motion?
The equilibrium position is where the object would naturally rest in the absence of force. The maximum displacement from equilibrium is called the amplitude X. The units for amplitude and displacement are the same, but depend on the type of oscillation.
What is the formula of time period of oscillation?
time is called T, the period of oscillation, so that ωT = 2π, or T = 2π/ω. The reciprocal of the period, or the frequency f, in oscillations per second, is given by f = 1/T = ω/2π.
What do you mean by time period?
time period (plural time periods) The length of time during which an activity occurs or a condition remains. It may be measured either in seconds or in millions of years, depending upon the nature of the activity of condition being considered.
At what position acceleration of the simple oscillatory pendulum is maximum and why?
At either position of maximum displacement, the force is greatest and is directed toward the equilibrium position, the velocity (v) of the mass is zero, its acceleration is at a maximum, and the mass changes direction.
What is period of oscillatory motion in physics?
The time taken for one complete to the fro motion of a particle is known as the period of oscillation.
What conditions are necessary for oscillatory motion?
What conditions must be met to produce SHM? The restoring force must be proportional to the displacement and act opposite to the direction of motion with no drag forces or friction. The frequency of oscillation does not depend on the amplitude.
What are the characteristics of oscillatory motion?
Time period (or) Frequency. Phase. Amplitude. Velocity.
What is difference between mean position and equilibrium position?
The mean position, also known as the equilibrium position, is the body’s position when there is no net force acting on it. In oscillatory motion, the phase of a particle is: This depicts the particle’s vibrational state at any given time.
What is meant by equilibrium position?
(noun) The point in a chemical reaction at which the concentrations of reactants and products are no longer changing.
Is mean position and equilibrium same?
Mean position is generally used term in case of oscillating systems and refers to the position about which the oscillating particle moves and the particle (like a pendulum bob) would eventually stop after the oscillations have died down. So, in other terms it would be position of stability or equilibrium.
How do you find time with oscillation and frequency?
The frequency f = 1/T = ω/2π of the motion gives the number of complete oscillations per unit time. It is measured in units of Hertz, (1 Hz = 1/s).
What is the time period of an oscillating pendulum?
The time period of oscillations of a simple pendulum is T=2π√Lg.
How do you calculate time in circular motion?
The period, symbolized by the letter T , is the length of time required for one complete rotation of the circle. The formula given below shows the average speed of an object moving in a circular motion 2 π R T . The time period for circular motion is mathematically defined as T = 2 πR v where v is velocity .
What is the difference between time and time period?
Answer. time is actual in which we work and time period is a work of long going process. our or any thing which is repeating continously at a time period.
What is a time period in physics?
The time period is the time taken by a complete cycle of the wave to pass a point. Angular frequency is angular displacement of any element of the wave per unit of time.
What is an example of a period of time?
The definition of a period is a space of time between two events or a portion of time. An example of period is the Renaissance era. An example of period is the first class of the day.
Why at mean position the acceleration is zero?
At mean position, the displacement of the particle is zero. Here, k is the force constant and x is the displacement from the mean position. Here, m is the mass of the particle and a is the acceleration. Therefore, the acceleration of the particle at mean position is zero.
Why acceleration is Max at extreme position in SHM?
Acceleration of particle is given by ω2x, where x is the displacement. Acceleration is maximum equal to aω2 (here a is amplitude) when it attains the extreme position as the displacement is maximum at extreme position.
What is the mean position of a simple pendulum?
A simple pendulum can be described as a device where its point mass is attached to a light inextensible string and suspended from a fixed support. The vertical line passing through the fixed support is the mean position of a simple pendulum.
What do you mean by time period of an oscillating body?
A periodic motion taking place to and fro or back and forth about a fixed point, is called oscillatory motion. e.g., motion of a simple pendulum, motion of a loaded spring etc. Time taken by the body to complete one oscillation is known as time period.
On what factors does the time period of oscillation depends?
The time period T of oscillation of a simple pendulum depends on the following quantities : Length of the pendulum(l) Mass of the bob ( m) Acceleration due to gravity (g) Derive an expression for T using dimensional method.
Is an oscillation the same as a period?
And the answer is no. The word “period” means something very specific, and is not the same thing as an oscillation in either meaning. A “period” is not the act of swinging, but the time for a complete cycle of the oscillation (from maximum to maximum).
Which of the following is not an oscillatory motion?
This is Expert Verified Answer d) Motion of a horse pulling a cart. As horse pulls a cart is only one direction, it’s not an oscillatory motion.
