In words:

  • the 2 tells us it will be 2 times taller than usual, so Amplitude = 2
  • the usual period is 2 π, but in our case that is "sped up" (made shorter) by the 4 in 4x, so Period = π/2
  • and the −0.5 means it will be shifted to the right by 0.5

Amplitude is the distance between the center line of the function and the top or bottom of the function, and the period is the distance between two peaks of the graph, or the distance it takes for the entire graph to repeat. Using this equation: Amplitude =APeriod =2πBHorizontal shift to the left =CVertical shift =D.

Full Answer

Is amplitude same as period?

Amplitude—maximum displacement from the equilibrium position of an object oscillating around such equilibrium position; Frequency—number of events per unit of time; Period—time it takes to complete one oscillation; For waves, these variables have the same basic meaning.

What is the formula for finding period?

Listed below are three main aspects to finding the formula for period:

  • Find if it is a periodic function i.e. if the function repeats over at a constant period
  • If the formula for period function is represented like f (x) = f (x + p), where p is the real number
  • Period means the time interval between the two occurrences of the wave

What is the amplitude, period, and midline of the function?

We know that the standard functions (f(t) = sin(t)) and (g(t) = cos(t)) are circular functions that each have midline (y = 0text{,}) amplitude (a = 1text{,}) period (p = 2pitext{,}) and range ([-1,1]text{.}) Our work in Preview Activity 2.4.1suggests the following general principles.

How do you find the period of the frequency?

Calculate the period of oscillations according to the formula above: T = 2π√ (L/g) = 2π * √ (2/9.80665) = 2.837 s . Find the frequency as the reciprocal of the period: f = 1/T = 0.352 Hz . You can also let this simple pendulum calculator perform all calculations for you!

How do you find amplitude?

The Amplitude is the height from the center line to the peak (or to the trough). Or we can measure the height from highest to lowest points and divide that by 2.

Is amplitude same as period?

Amplitude: The distance from the center of motion to either extreme. Period: The amount of time it takes for one complete cycle of motion.

How do you find the amplitude and maximum period?

How many amplitudes are in a period?

Gert's answer correctly states that the motion for one full cycle will hit the two extremes of (position) amplitude exactly once. But if you allow for extremes of velocity to be called "amplitudes" as well, you can add two more points (the zero crossings).

How do you find amplitude and frequency?

The formula to calculate the frequency in terms of amplitude is f= sin-1y(t)A-∅2πt. The formula to calculate the amplitude in terms of frequency is the same as that of the relation between them.

How do you find amplitude in simple harmonic motion?

A simple harmonic motion is given by the following equation. x(t)=Acos(ωt) x ( t ) = A cos ⁡ |A| is the amplitude of the periodic motion, which is the maximum magnitude of the object's displacement.

How do you find the amplitude of oscillation?

x(t) = A cos(ωt + φ). A is the amplitude of the oscillation, i.e. the maximum displacement of the object from equilibrium, either in the positive or negative x-direction.

What is the amplitude of a wave?

amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path.

So this function has a period equal to 8 and an amplitude equal to positive 1/2.

What is the amplitude of a function?

Explanation: The amplitude of a function is the amount by which the graph of the function travels above and below its midline. When graphing a sine function, the value of the amplitude is equivalent to the value of the coefficient of the sine.

What is amplitude in sine graph?

The amplitude of the sine and cosine functions is the vertical distance between the sinusoidal axis and the maximum or minimum value of the function. In relation to sound waves, amplitude is a measure of how loud something is.

What is the relation of amplitude and time period?

Amplitude—maximum displacement from the equilibrium position of an object oscillating around such equilibrium position. Frequency—number of events per unit of time. Period—time it takes to complete one oscillation.

What is a period equal to?

Frequency and Period are in reciprocal relationships and can be expressed mathematically as: Period equals the Total time divided by the Number of cycles.

What is the relationship between amplitude and period of a pendulum?

Increasing the amplitude means that there is a larger distance to travel, but the restoring force also increases, which proportionally increases the acceleration. This means the mass can travel a greater distance at a greater speed. These attributes cancel each other, so amplitude has no effect on period.

What is the relationship between amplitude and period of oscillation?

Answer. Answer: The maximum x-position (A) is called the amplitude of the motion. The block begins to oscillate in SHM between x=+A and x=−A, where A is the amplitude of the motion and T is the period of the oscillation.

What is frequency in math?

Frequency is how often something happens per unit of time (per "1").

What is the term for the period of a phase shift?

Amplitude, Period, Phase Shift and Frequency. and are called Periodic Functions. The Period goes from one peak to the next (or from any point to the next matching point): The Amplitude is the height from the center line to the peak (or to the trough).

What is it called when frequency is per second?

When frequency is per second it is called "Hertz".
