List of top Physics Questions on Energy in simple harmonic motion asked in AP EAPCET

In the arrangement shown, \[ k_1=1500\,\text{N m}^{-1}, \qquad k_2=500\,\text{N m}^{-1}, \] \[ m_1=2\,\text{kg}, \qquad m_2=1\,\text{kg}. \] The potential energy stored in the system of springs in equilibrium is (spring masses negligible and \(g=10\,\text{ms}^{-2}\)).

If the amplitude of a lightly damped oscillator decreases by \(1.5\%\), then the mechanical energy of the oscillator lost in each cycle is

A body is executing S.H.M. At a displacement \(x\), its potential energy is \(9\;J\) and at a displacement \(y\), its potential energy is \(16\;J\). The potential energy at displacement \((x+y)\) is

If the potential energy at a displacement \(x\) is numerically equal to the square root of potential energy at a displacement \(y\), then (where \(\omega\) is angular velocity):

A block is executing simple harmonic motion and its position is given by \(x = A \cos(\omega t + \phi)\). At time \(t = 0\), the ratio of the kinetic energy to the potential energy is \(\frac{1}{3}\). The magnitude of the phase angle \(\phi\) is:

Position of a \(2\,\text{kg}\) mass moving along the \(x\)-axis is given by \[ x=2\cos[(2\,\text{s}^{-1})t]\ \text{m}. \] Then maximum kinetic energy of the mass in joule is
