Whet is the ratio between the potential energy the total energy of a particle executing S.H.M, when it's displacement is half of its amplitude?

What is phase difference between the displacement and acceleration of a particle executing S.H.M ?

The ratio of kinetic energy to the potential energy of a particle executing SHM at a distance equal to half its amplitude, the distance being measured from its equilibrium position is:

The total energy of a particle vibrating in SHM is proportional to the square of its………..

Tabulate the values of displacement, velocity and aceleration of particle executing S.H.M.

When the separation between two charges is increased, the electric potential energy of the charges

If the zero of potential energy is at infinity, the total energy of an orbiting satellite is negative of its kinetic/potential energy.

The total work done on a particle is equal to the change in its kinetic energy

If the total mechanical energy of a particle is zero is its linear momentum necessarily zero? Is it necessarily nonzero?
