On what factors does the total energy in SHM depends?

Amplitude, time period and displacement.

What does the total energy depend on?

Objects have kinetic energy whenever they are moving. The kinetic energy of an object depends on its mass and how fast it is moving. When a system contains more than one object, it can also have potential energy, which is stored energy that depends on the position of the objects in the system.

Does angular frequency change in SHM?

In uniform circular motion, angular velocity and angular frequency will be same. But in simple harmonic motion, the angular velocity and angular frequency will be different. For example, in a pendulum, a bob released at a height where angular velocity is zero, but angular frequency is a constant.

Why is angular frequency used in SHM?

Simple harmonic motion is repetitive. The period T is the time it takes the object to complete one oscillation and return to the starting position. The angular frequency ω is given by ω = 2π/T. The frequency f = 1/T = ω/2π of the motion gives the number of complete oscillations per unit time.

What is the total energy of a particle in SHM?

At the mean position, the velocity of the particle in S.H.M. is maximum and displacement is minimum, that is, x=0. Therefore, P.E. =1/2 K x2 = 0 and K.E. = 1/2 k ( a2 – x2) = 1/2 k ( a2 – o2) = 1/2 ka2. Thus, the total energy in simple harmonic motion is purely kinetic.

What fraction of the total energy is kinetic when the displacement is one half of the amplitude?

Kinetic energy is equal to three fourth (i. e. 34) of the total energy, when the displacement is one-half of its amplitude.

What does angular frequency depend on?

The angular frequency depends only on the force constant and the mass, and not the amplitude. The angular frequency is defined as ω=2π/T, ω = 2 π / T , which yields an equation for the period of the motion: T=2π√mk.

Does angular frequency depend on time?

In wave mechanics, any given wave contains parameters such as frequency, time period, wavelength, amplitude, etc. The angular frequency is an important computation for an object having periodic motion….Angular Frequency Formula.

What is the relation between frequency and angular frequency?

Angular frequency ω (in radians per second), is larger than frequency ν (in cycles per second, also called Hz), by a factor of 2π. This figure uses the symbol ν, rather than f to denote frequency. A sphere rotating around an axis. Points farther from the axis move faster, satisfying ω = v / r.

What is the frequency of kinetic energy in SHM?

As we know, frequency of SHM is reciprocal of time period, so frequency of SHM is 1/t. But frequency of kinetic energy of body is twice its frequency of SHM. Hence, the frequency of the kinetic energy of a body in SHM is 2/t.
