Energy of a Pendulum
You will need:
1m of string
100g hooked mass
1. Make a pendulum by tying the string around the hook of the mass.Use the marker and the meterstick to mark points on the string that are 50cm , 70cm, and 90cm away frm the mass.
2. Hold the string at the 50cm mark. To swing the pendulum, gently pull the mass to the side, and release the mass without pushing it. Make 10 swings or the pendulum.
3. record the data. Consider how fast and how high the pendulum swings. Repeat steps 2 and 3 while holding the string at the 70cm mark, and the 90cm mark record the data.
P.S. A pendulum is an example of a evice that converts potiential energy into kinetic energy and back.
