State at which point during an oscillation the oscillator has zero velocity but positive acceleration ?

In a simple harmonic oscillator, at the mean position

A simple pendulum of length 1 m is freely suspended from the ceiling of an elevator. The time period of small oscillations as the elevator moves up with an acceleration of 2m//s^2 is (use g=10 m//s^2 )

A mass is suspended from a vertica spring which is executing SHM of frequency 5 Hz. The spring is unstretched at the highest point of oscillation. Maximum speed of the mass is (take, acceleration due to gravity, g=10m//s^(2) )

State the factors on which time period of angular oscillations depend on

When the potential energy of a particle executing simple harmonic motion is one-fourth of its maximum value during the oscillation, the displacement of the particle from the equilibrium position in terms of its amplitude a is

Explain velocity time graph of a particle having Constant velocity (ii) uniform positive acceleration (iii) uniform negative acceleration (iv) non- uniform acceleration.

A particle performs linear S.H.M. At a particular instant, velocity of the particle is 'u' and acceleration is ' prop ' while at another instant, velocity is 'v' and acceleration ' beta ' (0ltpropltbeta) . The distance between the two position is

Two points are located at a distance of 10 m and 15 m from the source of oscillation. The period of oscillation is 0.05 s and the velocity of the wave is 300m//s . What is the phase difference between the oscillation of two points?

Find out the correlation Uniform circular motion: Displacement is zero :: Uniform velocity : Acceleration is zero

For a particle in a non-uniform accelerated circular motion: (i) Velocity is radial and acceleration is transverse only (ii) Velocity is transverse and acceleration is radial only (iii) Velocity is radial and acceleration has both radial and transverse components (iv) Velocity is transverse and acceleration has both radial and transverse components
