| Particle Speed/Energy Meter: This meter measures the average speed or kinetic energy of liquid or solid particles. You must attach the speed/energy meter to an orange hotspot on the Ultrascope (see Ultrascope View (Freezing and Melting)). In the Properties Box of the speed/energy meter, you can choose whether to measure average speed or average energy. You can choose to either liquid or solid particles. You must place an average speed/energy meter and choose to measure speed to plot speed using the graph tool. You must choose to measure average energy to plot energy.
