At time $t = 0$,a simple harmonic oscillator is at its extreme position. If it covers half of the amplitude distance in $1\, s$,then the time period of oscillation is ..... $s$.

$A$ particle executes $S.H.M.$ between $x = -A$ and $x = +A$. The time taken for it to go from $x = 0$ to $x = A/2$ is $T_1$,and from $x = A/2$ to $x = A$ is $T_2$. Then:

Explain with plots the position of a particle executing simple harmonic motion at different times.

$A$ particle is executing $SHM$ of amplitude $A$ about the mean position $x = 0.$ Which of the following cannot be a possible phase difference between the positions of the particle at $x = +A/2$ and $x = -A/\sqrt{2}$ (in $^o$)?

Two particles are executing $S.H.M.$ of same amplitude and frequency along the same straight line path. They pass each other when going in opposite directions,each time their displacement is half of their amplitude. What is the phase difference between them?

Explain what is phase and draw a single graph showing different phases of simple harmonic motion.
