[|Practice questions on SHM and solutions from very old IB examinations]

media type="custom" key="25690760" Describe examples of oscillations. [|COMPARING EXAMPLES OF SHM] - link to java applet

Define the terms //displacement//, //amplitude//, //frequency//, //period// and //phase difference// **FILM OF A WAVE PENDULUM - what does this tell you about phase difference?** media type="custom" key="25758096" You can use this video to calculate the lengths of the pendulum cords. The connection between frequency and period should be known.


 * f = 1/T and T = 1/f **

Define //simple harmonic motion// (//SHM//) and state the defining equation as:

Students are expected to understand the significance of the negative sign in the equation and to recall the connection between //ω// and //T//.

**f = 1/T and T = 1/f** = =

//ω = 2π/T and // //T = 2π/ω and // //ω = 2πf//// and ωT = 2π// // and ω/2π = f//
= = Solve problems using the defining equation for SHM.

The two left-hand equations have x=0 when t=0 The two right-hand equations have x=x 0 when t=0 The bottom equation shows v against x

[|ILLUSTRATION OF SHM WITH GRAPHS] Java applet from Walter Fendt [|HOW WAVE PARTICLES EXECUTE SHM] Java applet

Solve problems, both graphically and by calculation, for acceleration, velocity and displacement during SHM.

ACTIVITY: Download the file in Section 4.2 and complete the formulas for motion and make the charts.
