Part 1: 1. Select a suitable initial length and mass for the pendulum (for which the
pendulum does not swing too fast or too slow) for example 30 cm and 1.0 kg.
2. Start by displacing the pendulum through a small angle (less than 10°) then
release it.
3. Complete the table below.

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.

hope that !                                         : )

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.
