Period
2.01 s
Angle
30°
Bob speed
0.00 m/s
How to use: Drag the String length slider to change the
pendulum. Drag the Bob mass slider to change how heavy the bob is.
Watch the Period readout — the time for one full swing.
Change mass first. Then change length. Which one changes the period?
Notice: changing mass does not change the period — only the string length does. Longer string, slower swing.
