Activity Three Falling Objects Bounce The frames for the bounce should "pulse" as the ball bounces, so it's more like a bubble than a ball. At the least it should play through the loops of 12 frames upon impact with the ground plane (if any) Moon Mars The Sun Rebound On the Moon, Mars and Earth, the ball should bounce, or at least stay Ticks put when it hits the defined ground Geneva 9pt plane. Aliased, centered on each tick On Jupiter it should fall through, but the indicator will note the time elapsed when it crossed the "ground plane" On the sun it should either fall through as it does for Jupiter or burn up! Earth Jupiter Vector Labels Different colors warrent the slight change of text color on the labels. The colors for fhe vector labels are: Vy (green) Moon / Mars / Earth R100 G255 B70 Jupiter / Sun R30 G170 B0 Ay (yellow) Moon / Mars / Earth R255 G250 B165 Jupiter / Sun R255 G255 B255 Position Readout This stays in one place at the bottom of the screen, showing the current For all of the labels, the typeface is position of the cart with digits.

Major Ticks Every 22 "boxes" or 110 pixels Button Labels Vy = R170 G140 B0 Ay = R0 G180 B0 Vx = R210 G70 B70 Vy = R5 G0 B200 Readout Type Geneva 9pt Aliased, Centered Activity Six Object on an incline Masses All of the masses are in one cast member! To change masses, change the frame of the Flash member from 1–10. Warning The modal boxes for this and any other activity doesn’t just appear, but floats and fades in from the bottom of the activity area. As it displays it bobs up and down slowly by two or three pixels. The box is dismissed and the sliders are reset when the user clicks anywhere in the activity area. In cases where the text needs to be changed, the font is sliderBold, 12/14pt black. Platform The "hoists" move according to therotation of the base platform. A clockwise movement makes the left hoist move up and the right hoist move down the same distance, while a counter-clockwise movement makes the opposite happen. Activity Twelve RC Combo Piece de lá resistance The light bulb has ten different wire thicknesses corresponding to various levels of resistance. The glow can be controlled in Director Read all about it Fill ‘er up using a solid color shape and the It's a little redundant, but there are Through a sandwich of a capacitor gray mask provided. several places to track the values graphic, a color swatch and a overlapping of the capacitor, light bulb resistance mask, the capacitor can appear to “fill” To change intensity, you can change the and battery voltage. with color based on how much charge size and opacity of the color shape. it’s currently holding. a) the little signs by the components Note: it's advisble in 16-bit color to use b) the schematic See CapacitorFill.dir an 8-bit gray scale mask in Director. You c) the sliders can't use 16-bit cast members effectively as masks. The only alternative is 32-bit members, which won't be converted on-the-fly to 16-bit well. Switch is switch? When the little yellow switch is to the left, the capacitor and light bulb are an open circuit, so the light bulb should glow according to the current provided by the capacitor. re-volt-ing The battery doesn’t change appearance. Conversely, the battery shoudl charge Only the voltage rating next to it gives up the capacitor in real time when the any kind of indication to it's value. switch is in the other position. The battery, for purposes of this example, has an unlimited charge. Schematically correct The schematic diagram shows the setup in a more abstract manner. The readouts are done using text members, with the exception the Omega symbol for ohm. The switch should change positions Paint by number reflecting the “real” setup. there are ten graphics for the digits 0–9. Clicking on the switch area of the diagram They should be positioned in an should also change the switch position. upward slant to one another, mainly because everything in this perspective is at this angle Verdana 9 pt Aliased Activity Thirteen AC circuits Read all about it AC what you mean Little panels next to the capacitor and resistor note the values. There are three sequences: low, medium and high that animate in this The sizes of the components don't oscillioscope based on the frequency change as they did in activity 12. setting. It's not intended to be accurate. Sine you very much This little sine wave in the schematic just continually moves. Activity Fifteen Elementary Particles Open Trajectory Paths of the particles are traced using colors. Red:R255 G0 B0 Magnetic Personality Yellow: R235 G215 B0 In Act_15.psd, there are the examples Blue: R0 G0 B255 are magnetic field settings, and hopefully what they'll look like when the user zooms out. Particles get smaller when zoomed out. I'm not sure how you'd want to handle units and scaling. French Fried Rotatoes Clicking on this button rotates the field clockwise 90 (Electric Field Only). For Magnetic Field (above) each button selects a different orientation. Go Green! ...I mean, go Blue, er... Included is the same "start" animation from Act 1. This button fires the selected particles into the seleced field, and the fun begins. Vector? I don’t even know her! You may want to just use the cases I've provided in Act_15.psd (I didn't put them in Elements) for the five cases. For magnetic fields, I have provided examples on just the in/out cases. You can use the same vectors from the electric field for the L - R magnetic field instances. Particle Man These are always visible for selection. Rolling over the view window makes the particle bob up and down. Clicking dims the window,and makes the particle part of the next simulation.
