These different ways are called resonant modes . Each push then can add a little kinetic energy to the ball. Eventually, there will be enough kinetic energy added to the ball to get it to the rim and over the top. Diagrams Scientists draw diagrams all the time. They use diagrams as a tool to support and guide their own thinking, as well as a device for explaining their ideas to others.

A common thread in these statements seems to be the perception that a diagram is a decoration, not a tool.

Readability A diagram must be large enough to see and interpret easily.
