Observation

A pendulum is a hanging weight that swings back and forth, like the swinging arm on a grandfather clock or a swing on a playground. When you pull a swing - or any pendulum - up to one side, gravity tugs it back down. But since the swing is attached by a rope or chain, it doesn’t just drop to the ground. Instead, it swings back and forth, over and over.

But what happens when you have a bunch of different-sized pendulums swinging together? Make this mesmerizing pendulum wave toy to find out!

Explanation:

the pull of gravity on the rocket decreases

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )
