Flash Interactive - Pistons and the Period of a Sine Curve (from www.intmath.com)

Here's another interactive that you can use to explore the concept of period and frequency. The frequency = 1/period. We'll see more on this below.

The piston engine is the most commonly used engine in the world. Its motion can be described using a sine curve.

Things to Do

1. Click "Start" and you will see a sine curve traced out as the piston goes up and down.
2. Now, change the value of b using the slider. If you increase b, the period for each cycle will go down and the frequency will increase. Click "Start" again to see the effect of your change.
3. Observe the number of cycles that you see between t = 0 and t = 2π. For b = 1 you see one cycle, for b = 2, you see 2 cycles, and so on. If b < 1, you do not see any complete cycles.

The units along the horizontal (time) axis are in radians. So 3.14 = π radians and 6.28 = 2π radians.
