A pendulum is a weight attached to a fixed point that swings

A pendulum is a weight attached to a fixed point that swings back and forth. It is a great example to demonstrate the ________ from ________ to ________ and back again. In the activity, the pendulum had five positions. When the weight was pulled back and not released, it had only ________. After it was released, it was traveling the fastest at position ________. At this point it had only ________ because all of the ________ was transformed to ________. At the halfway point (positions 2 and 4), it had both ________________. When it reached the opposite end of the swing, position 5, it again had only ________. Later, the weight made five complete swings. It did not ________________. The reason it did not return to its original position was because some energy ________. The lost energy was converted to ________ due to ________.

Solution

1. transformation

3. potential energy

4. one (1)

5.kinetic energy

6.potential energy

7.kinetic energy

8.kinetic energy and potential energy

9.potential energy

10.return to original position

11. dissipated

12.heat

13. friction or air resistance
