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.

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

i would say
