Define simple harmonic motion.

Which of the following examples represent (nearly) simple harmonic motion and which represent periodic but not simple harmonic motion? General vibrations of a polyatomic molecule about its equilibrium position.

Figure 3.23 gives the x-t plot of a particle executing one-dimensional simple harmonic motion. (You will learn about this motion in more detail in Cliapterl4). Give the signs of position, velocity and acceleration variables of the particle at t = 0.3 s, 1.2 s, - 1.2 s.

Every simple harmonic motion is periodis, is the reverse also true .

Plot the corresponding reference circle for each of the following simple harmonic motions. Indicate the initial (t =0) position of the particle, the radius of the circle, and the angular speed of the rotating particle. For simplicity, the sense of rotation may be fixed to be anticlockwise in every case: (x is in cm and t is in s). x =-2 sin (3t+(pi//3))

Indicate the initial (t =0) position of the particle, the radius of the circle, and the angular speed of the rotating particle. For simplicity, the sense of rotation may be fixed to be anticlockwise in every case: (x is in cm and t is in s). x =3 sin (2pit+(pi//4))
